Psychosocial group intervention for patients with primary breast cancer: a randomised trial.

To test the effectiveness of a psycho-educational group intervention to improve psychological distress measured by POMS TMD, Quality of Life measured by European Organisation for Research and Treatment of Cancer (EORTC), the core and breast cancer module, Mental Adjustment measured by MAC and marital relationship measured by BLRI in women with primary breast cancer conducted 10 weeks after surgery. A secondary outcome was 4-year survival.



We randomly assigned 210 patients with primary breast cancer to a control or an intervention group. Patients in the intervention group were offered two weekly 6-h sessions of psycho-education and eight weekly 2-h sessions of group psychotherapy. All participants were followed up for Quality of Life, coping ability and social relations 1, 6 and 12 months after the intervention and on survival 4 years after surgical treatment.



No statistically significant effects of the intervention were found on any of the psychosocial questionnaire outcomes. There were not enough cases of death to analyse overall survival. The only statistically significant result was for patients who used anti depressive medication, for whom almost all measures improved over time, in both the control and intervention groups.



Psycho-education and group psychotherapy did not decrease psychological distress or increase Quality of Life, Mental Adjustment or improve marital relationship among patients with primary breast cancer.
Japan assessment of pitavastatin and atorvastatin in acute coronary syndrome (JAPAN-ACS): rationale and design.

Many trials have shown that 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitors reduce the incidence of cardiovascular events and mortality. One method of decreasing the incidence of cardiovascular events could be to reduce the progression of coronary atherosclerosis, and a recent study found that atorvastatin can cause coronary plaque to regress. To generalize this finding, using conventional HMG-CoA reductase inhibitors at many Japanese centers, randomized trials of pitavastatin and atorvastatin will be conducted with patients with acute coronary syndrome (ACS).



Patients with ACS who have undergone successful percutaneous coronary intervention under intravascular ultrasound guidance will be studied. They will be randomly allocated to pitavastatin or atorvastatin groups and followed up for 8-12 months. The primary endpoint will be the percent change in coronary plaque volume, and secondary endpoints will include absolute changes in coronary plaque volume, serum lipid levels and inflammatory markers. The safety profile will also be evaluated.



This study will examine the ability of HMG-CoA reductase inhibitors to regress coronary plaque in Japanese patients with ACS and the findings should help to improve the prognosis of such patients and clarify the involved mechanisms.
Lactobacillus gasseri KS-13, Bifidobacterium bifidum G9-1, and Bifidobacterium longum MM-2 Ingestion Induces a Less Inflammatory Cytokine Profile and a Potentially Beneficial Shift in Gut Microbiota in Older Adults: A Randomized, Double-Blind, Placebo-Controlled, Crossover Study.

This study determined whether older adults who consumed a probiotic mixture would have a greater proportion of circulating CD4+ lymphocytes, altered cytokine production, and a shift in intestinal microbiota toward a healthier microbial community.



Participants (70 ± 1 years [mean ± SEM]; n = 32) consumed a probiotic (Lactobacillus gasseri KS-13, Bifidobacterium bifidum G9-1, and Bifidobacterium longum MM2) or a placebo twice daily for 3 weeks with a 5-week washout period between intervention periods. Blood and stools were collected before and after each intervention. The percentage of circulating CD4+ lymphocytes and ex vivo mitogen-stimulated cell cytokine production were measured. In stools, specific bacterial targets were quantified via quantitative polymerase chain reaction (qPCR) and community composition was determined via pyrosequencing.



During the first period of the crossover the percentage of CD4+ cells decreased with the placebo (48% ± 3% to 31% ± 3%, p < 0.01) but did not change with the probiotic (44% ± 3% to 42% ± 3%) and log-transformed concentrations of interleukin-10 increased with the probiotic (1.7 ± 0.2 to 3.4 ± 0.2, p < 0.0001) but not the placebo (1.7 ± 0.2 to 2.1 ± 0.2). With the probiotic versus the placebo a higher percentage of participants had an increase in fecal bifidobacteria (48% versus 30%, p < 0.05) and lactic acid bacteria (55% versus 43%, p < 0.05) and a decrease in Escherichia coli (52% versus 27%, p < 0.05). Several bacterial groups matching Faeacalibactierium prausnitzii were more prevalent in stool samples with the probiotic versus placebo.



The probiotic maintained CD4+ lymphocytes and produced a less inflammatory cytokine profile possibly due to the changes in the microbial communities, which more closely resembled those reported in healthy younger populations.
Comparison of 15-year survival for men and women after initial medical or surgical treatment for coronary artery disease: a CASS registry study. Coronary Artery Surgery Study.

This study compared the rates of coronary artery bypass graft surgery and 15-year survival for men and women after initial medical or surgical management.



There has been concern that women with coronary artery disease are managed differently than men and that men and women have a different prognosis. The Coronary Artery Surgery Study (CASS) registry is a large data base of well characterized patients with long-term follow-up.



Patients underwent cardiac catheterization at 1 of 15 hospitals during 1974 to 1979. Bypass surgery rates were based on 12,452 men and 2,366 women. Survival results were based on 6,018 men and 1,095 women with operable coronary artery disease and initial medical management and 6,922 men and 1,291 women initially managed surgically.



At 15 years, bypass surgery rates were 75% for men and 72% for women (p = 0.91). The rates remained similar after adjustment for clinical and angiographic variables. The 15-year survival rate was 50% for men and 49% for women with initial medical treatment (p = 0.53) and 52% for men and 48% for women (p = 0.004) with initial surgical treatment, a difference similar to that for operative mortality (men 2.5%, women 5.3%, p < 0.0001). Survival was improved by bypass surgery in most subgroups, with largest relative risks for high risk patients. Relative risks were similar for men and women.



The rate of bypass surgery did not differ between men and women. There were few differences in the survival of men and women. In general, both men and women with initial surgical treatment survived longer, although benefits were clinically and statistically significant only in those at high risk. The benefit was similar in both men and women.
[Temporal evolution of treatment of patients with atrial fibrillation in a urban health care area].

To evaluate the adequacy of atrial fibrillation (AF) management 6 years after the establishment of a coordinated AF Unit.



Patients with AF attended during 14 consecutive days in the Emergency Room, Internal Medicine, Neurology and Arrhythmia departments of a tertiary hospital, and 3 primary health care centers of the same urban health care area were included. Treatment for AF and its adequacy to current clinical guidelines, tests performed and knowledge about the arrhythmia were evaluated. Results were compared with a population of 239 patients treated 6 years earlier.



One hundred and sixty-eight patients were included. Knowledge of the arrhythmia improved. The adequacy of treatment (rate control, rhythm control and antithrombotic prophylaxis) remained at the same level as in the previous period in all areas. The adequacy of thromboprophylaxis was negatively associated with advanced age (P < .001) and positively associated with knowledge of arrhythmia (P = .026).



Treatment of AF in a coordinated health area remains appropriate 6 years after the establishment of a coordinated AF unit. Elderly patients are still poorly anticoagulated. Health education may improve this deficit.
Migraine frequency and health utilities: findings from a multisite survey.

Assess the relationship between migraine frequency and health utility.



Patients aged >/=18 years diagnosed with episodic migraine were enrolled at three US sites representing varied models of health-care delivery. All subjects completed a questionnaire that included demographic and clinical information, a migraine-specific disability questionnaire, and the Health Utilities Index Mark 3 (HUI3). The HUI3 is a generic health status and health-related quality-of-life measure. HUI3 health status data are translated into utility scores anchored by 0 (dead) and 1 (perfect health).



The study enrolled 150 patients. The mean age was 44 years and 87% were female. Mean (+/-SD) monthly migraine frequency was 4.4 +/- 3.6, with 34% reporting </=2 migraines per month and 20% reporting >6 migraines per month. The mean (+/-SD) HUI3 score was 0.62 +/- 0.26. After controlling for study center, demographics, comorbidities, migraine characteristics, and level of migraine disruptiveness, migraine frequency was found to be significantly (P < 0.05) and negatively associated with HUI3 scores. Subjects with >6 migraines per month had an adjusted mean HUI3 score of 0.41; the corresponding mean for those reporting </=2 migraines per month was 0.67. Migraine frequency was positively associated with higher levels of disability for the emotion, cognition, and pain components of the HUI3.



Among this group of care-seeking patients, migraineurs' health utilities were inversely related to headache frequency. Although these data may not be generalizable to the entire migraine population, they may be useful in assessing the comparative cost-effectiveness of preventive migraine therapies.
School-based drug prevention among at-risk adolescents: effects of ALERT plus.

In a recent randomized field trial, Ellickson et al. found the Project ALERT drug prevention curriculum curbed alcohol misuse and tobacco and marijuana use among eighth-grade adolescents. This article reports effects among ninth-grade at-risk adolescents. Comparisons between at-risk girls in ALERT Plus schools (basic curriculum extended to ninth grade with five booster lessons) and at-risk girls in control schools showed the program curbed weekly alcohol and marijuana use, at-risk drinking, alcohol use resulting in negative consequences, and attitudinal and perceptual factors conducive to drug use. Program-induced changes in perceived social influences, one's ability to resist those influences, and beliefs about the consequences of drug use mediated the ALERT Plus effects on drug use. No significant effects emerged for at-risk boys or at-risk adolescents in schools where the basic ALERT curriculum (covering seventh and eighth grades only) was delivered. Possible reasons for gender differences and implications for prevention programming are discussed.
Nephrectomy modifies renal angiotensin II effects in kidney donors.

Age, gender, menopausal status, a family history of hypertension, and renal vascular response to angiotensin II are involved in the progression of renal failure from its very beginning.



In order to investigate their importance on this progression, we measured effective renal plasma flow (ERPF) and glomerular filtration rate (GFR), and calculated glomerular pressure (Pglo) and afferent and efferent arteriole resistances (by means of Gomez formulae) in 26 normotensive kidney donors before and after nephrectomy.



Renal reactivity to angiotensin was the only variable that affected changes in renal and glomerular hemodynamics after the loss of renal tissue: in subjects with greater angiotensin reactivity, higher afferent resistances (Ra) and lower glomerular filtration and pressure before nephrectomy change to higher efferent resistances (Re) and higher Pglo and filtration after nephrectomy.



In normotensive donors with a normal compensatory response to nephrectomy, baseline renal reactivity to angiotensin II can influence renal and glomerular hemodynamics 1 year after nephrectomy.
Deep brain stimulation improves movement amplitude but not hastening of repetitive finger movements

External pacing cues, dopaminergic medication, and bilateral subthalamic nucleus deep brain stimulation (STN-DBS) improve repetitive movements performed at low rates. When the pacing rate is increased to frequencies near 2 Hz and above, both external pacing cues and Parkinson's medication were shown to be ineffective at improving repetitive finger movement performance. It remains unclear if STN-DBS improves the performance of repetitive finger movements at high pacing rates. This study examined the effects of STN-DBS on the amplitude and rate of repetitive finger movement across a range of external pacing rates. Nine participants with STN-DBS (OFF and ON stimulation) and nine matched healthy adults performed repetitive index finger flexion movements paced by an acoustic tone that increased from 1.0 to 3.0 Hz. OFF stimulation, most subjects moved at rates that were substantially higher (hastening pattern) or lower (bradykinesia pattern) than the tone rate, particularly at high pacing rates. ON stimulation, movement rate improved in subjects with the bradykinesia pattern, but not in those with the hastening pattern. Overall, STN-DBS did not significantly affect movement rate. In contrast, STN-DBS significantly (p<0.05) improved movement amplitude across all pacing rates. These findings demonstrate that STN-DBS improves movement amplitude, but had no effect on the rate of movement in participants with a hastening pattern. Separately testing movement amplitude and movement rate using both high and low rate externally paced cues in the clinical environment may aid in the diagnosis and treatment of people with Parkinson's disease.
Delayed gadolinium-enhanced magnetic resonance imaging (dGEMRIC) of hip joint cartilage in femoroacetabular impingement (FAI): Are pre- and postcontrast imaging both necessary?

The purpose of this study was to assess if delayed gadolinium MRI of cartilage using postcontrast T(1) (T(1Gd)) is sufficient for evaluating cartilage damage in femoroacetabular impingement without using noncontrast values (T(10)). T(1Gd) and DeltaR(1) (1/T(1Gd) - 1/T(10)) that include noncontrast T(1) measurements were studied in two grades of osteoarthritis and in a control group of asymptomatic young-adult volunteers. Differences between T(1Gd) and DeltaR(1) values for femoroacetabular impingement patients and volunteers were compared. There was a very high correlation between T(1Gd) and DeltaR(1) in all study groups. In the study cohort with Tonnis grade 0, correlation (r) was -0.95 and -0.89 with Tonnis grade 1 and -0.88 in asymptomatic volunteers, being statistically significant (P < 0.001) for all groups. For both T(1Gd) and DeltaR(1), a statistically significant difference was noted between patients and control group. Significant difference was also noted for both T(1Gd) and DeltaR(1) between the patients with Tonnis grade 0 osteoarthritis and those with grade 1 changes. Our results prove a linear correlation between T(1Gd) and DeltaR(1), suggesting that T(1Gd) assessment is sufficient for the clinical utility of delayed gadolinium MRI of cartilage in this setting and additional time-consuming T(10) evaluation may not be needed.
ω-3 and ω-6 Polyunsaturated fatty acid intakes and the risk of breast cancer in Mexican women: impact of obesity status.

ω-3 polyunsaturated fatty acids (PUFA) could play a protective role on the risk of breast cancer; however, little is known about this relation among Mexican women. We evaluated the association between ω-3 and ω-6 PUFA intake and breast cancer risk by obesity status in Mexican women.



A population-based case-control study was conducted in Mexico, including 1,000 incident breast cancer cases and 1,074 controls matched to cases by age, health care system, and region. Women provided information on health and diet by in-person interview. Body mass index (BMI) measures were used to define overall obesity. Obesity status was categorized as normal weight (18.5 < BMI < 25), overweight (25 ≤ BMI < 30), and obese (BMI ≥ 30). A conditional logistic regression model was used to assess the association between PUFA and breast cancer risk.



Overall, there was no significant association between ω-3 PUFA intake and breast cancer risk (P = 0.31). An increased risk of breast cancer was associated with increasing ω-6 PUFA intake in premenopausal women [OR = 1.92, 95% confidence interval (CI) = 1.13-3.26; P = 0.04]. A decreased risk of breast cancer was significantly associated with increasing ω-3 PUFA intake in obese women (OR = 0.58, 95% CI = 0.39-0.87; P = 0.008) but not in normal weight nor in overweight women (P(heterogeneity) = 0.017).



Obesity status may affect the association between ω-3 PUFA intake and breast cancer risk. The underlying mechanisms may be related to decreased inflammation and improved adipokin and estrogen levels induced by ω-3 PUFA in adipose tissue in obese women.



Increased intake of ω-3 PUFA should be recommended among Mexican women in particular in obese women.
The value of electrocardiography-gated multi-slice computed tomography in the evaluation of patients with chest pain.

Multi-detector spiral computed tomography with retrospective electrocardiography-gated image reconstruction allows detailed anatomic imaging of the heart, great vessels and coronary arteries in a rapid, available and non-invasive mode.



To investigate the spectrum of findings in 32 consecutive patients with chest pain who underwent CT coronary angiogram in order to determine the clinical situations that will benefit most from this new technique.



Thirty-two patients with chest pain were studied by MDCT using 4 x 1 mm cross-sections, at 500 msec rotation with pitch 1-1.5, intravenous non-ionic contrast agent and a retrospectively ECG-gated reconstruction algorithm. The heart anatomy was evaluated using multi-planar reconstructions in the axial, long and short heart axes planes. Coronary arteries were evaluated using dedicated coronary software and the results were compared to those of conventional coronary angiograms in 12 patients. The patients were divided into four groups according to the indication for the study: group A--patients with high probability for coronary disease; group B--patients after CCA with undetermined diagnosis; group C--patients after cardiac surgery with possible anatomic derangement; and group D--symptomatic patients after coronary artery bypass graft, before considering conventional coronary angiography.



Artifacts caused by coronary motion, heavy calcification and a lumen diameter smaller than 2 mm were the most frequent reasons for non-evaluable arteries. Assessment was satisfactory in 83% of all coronary segments. The overall sensitivity of 50% stenosis was 74% (85% for main vessels) with a specificity of 96%. Overall, the CTCA results were critical for management in 18 patients.



Our preliminary experience suggests that CTCA is a reliable and promising technique for the detection of coronary artery stenosis as well as for a variety of additional cardiac and coronary structural abnormalities.
A novel optical imaging method for the early detection, quantitative grading, and mapping of cancerous and precancerous lesions of cervix

Describes a novel optical imaging method for the in vivo early detection, quantitative staging, and mapping of cervical cancer and precancer. A multispectral imaging system was developed, which is capable of performing time-resolved imaging spectroscopy. The system was used in order to assess quantitatively the alterations in the light scattering properties of the cervix, induced selectively and reversibly in cervical neoplasias, after the application of acetic acid solution. Spectral imaging and analysis of cervix show that the maximum contrast between acetic acid responsive and nonresponsive areas is obtained at 525/spl plusmn/15 nm, which is further enhanced by cutting off the regular component of tissue reflection, with the aid of two linear cross polarizers. Successive snapshot imaging at this spectral band enables the quantitative assessment of the temporal alterations in the intensity of the backscattered light, in any spatial location of the examined area. Initial clinical trials show that optical contrast enhancement results in a notable improvement of the sensitivity in detecting incipient lesions. It was also shown that the measured temporal characteristics of the phenomenon contain specific information, which enables the differentiation between neoplastic and nonneoplastic lesions, as well as between neoplasias of different grade. The demonstrated improved sensitivity and specificity highlight the potential of the method in both clinical research and noninvasive diagnosis.
Women With Cardiogenic Shock Derive Greater Benefit From Early Mechanical Circulatory Support: An Update From the cVAD Registry.

The aim of this analysis was to assess survival differences between men and women supported with Impella 2.5 (Abiomed Inc., Danvers) in the setting of acute myocardial infarction (AMI) complicated by cardiogenic shock (CS).



Data on sex differences in outcomes of CS with mechanical circulatory support are sparse.



Patients enrolled in the cVAD Registry who underwent percutaneous coronary intervention (PCI) and Impella 2.5 support for CS complicating an AMI were included. Differences between men and women were examined.



In total, 180 patients were analyzed. Women (n = 49, 27.2%) were older (71.0 ± 12.8 years vs 63.8 ± 13.0, P = 0.001), smaller (BSA 1.82 ± 0.22 vs 2.04 ± 0.24 m(2) , P < 0.001), and had a higher STS mortality risk score than men (27.9 ± 17.0 vs. 20.8 ± 16.8 P = 0.01). There was no difference in survival to discharge (P = 0.3). Patients receiving the Impella 2.5 pre-PCI had significantly lower inpatient mortality than those who received support post-PCI (P = 0.003). However, the magnitude of the survival benefit was significantly greater in women who received the Impella pre-PCI as compared to men. Overall, 68.8% of women survived with pre-PCI Impella 2.5 versus 24.2% post-PCI (P = 0.005) whereas 54.2% of men survived with pre-PCI Impella 2.5 versus 40.3% post-PCI (P = 0.1, p-interaction = 0.07). No differences in timing to intervention were found between men and women.



Early initiation of hemodynamic support prior to PCI with Impella 2.5, in the setting of AMI complicated by CS, was associated with a greater survival benefit to hospital discharge in women compared to men, despite a higher predicted risk of mortality and a greater revascularization failure rate for women.
