Effects of Optimism and Gratitude on Physical Activity, Biomarkers, and Readmissions After an Acute Coronary Syndrome: The Gratitude Research in Acute Coronary Events Study.

Positive psychological constructs, such as optimism, are associated with beneficial health outcomes. However, no study has separately examined the effects of multiple positive psychological constructs on behavioral, biological, and clinical outcomes after an acute coronary syndrome (ACS). Accordingly, we aimed to investigate associations of baseline optimism and gratitude with subsequent physical activity, prognostic biomarkers, and cardiac rehospitalizations in post-ACS patients.



Participants were enrolled during admission for ACS and underwent assessments at baseline (2 weeks post-ACS) and follow-up (6 months later). Associations between baseline positive psychological constructs and subsequent physical activity/biomarkers were analyzed using multivariable linear regression. Associations between baseline positive constructs and 6-month rehospitalizations were assessed via multivariable Cox regression. Overall, 164 participants enrolled and completed the baseline 2-week assessments. Baseline optimism was significantly associated with greater physical activity at 6 months (n=153; β=102.5; 95% confidence interval, 13.6-191.5; P=0.024), controlling for baseline activity and sociodemographic, medical, and negative psychological covariates. Baseline optimism was also associated with lower rates of cardiac readmissions at 6 months (n=164), controlling for age, sex, and medical comorbidity (hazard ratio, 0.92; 95% confidence interval, [0.86-0.98]; P=0.006). There were no significant relationships between optimism and biomarkers. Gratitude was minimally associated with post-ACS outcomes.



Post-ACS optimism, but not gratitude, was prospectively and independently associated with superior physical activity and fewer cardiac readmissions. Whether interventions that target optimism can successfully increase optimism or improve cardiovascular outcomes in post-ACS patients is not yet known, but can be tested in future studies.
Outdoor gallery and its photometric issues

We have been developing an outdoor gallery system in Asukakyo. Asukakyo is one of the ancient capitals, which is well-known to has lots of temples, palaces and buildings. Nevertheless, most of the assets have been deteriorated after more than fourteen centuries. The outdoor gallery system introduces the virtual appearance of ancient Asukakyo to visitors at the original site with the help of Mixed Reality (MR). To reconstruct the virtual Asukakyo in the outdoor gallery system, it is necessary to handle occlusion problem in synthesizing virtual objects correctly into the real scene with respect to existing foregrounds and shadows. Furthermore, outdoor environment makes the task more difficult due to the unpredictable illumination changes. This paper proposes novel outdoor illumination constraints for resolving the foreground occlusion problem in outdoor environment for the outdoor gallery system. The constraints can be also integrated into a probabilistic model of multiple cues for a better segmentation of the foreground. In addition, we introduce an effective method to resolve the shadow occlusion problem by using shadow detection and recasting with a spherical vision camera. We have applied the method in our outdoor gallery system in Asukakyo and verified the effectiveness of the method.
Prevention of contrast-induced nephropathy with Na/K citrate.

Contrast-induced nephropathy (CIN) is a frequent complication of many radiological procedures involving the application of contrast media. It represents a significant health problem that causes the increase in mortality, morbidity, and medical costs. For the prevention of CIN, a number of methods have been proposed to be effective. Among them, alkalinization of urine takes an important place. Although the Na/K citrate is a well-known agent for urine alkalinization, it has not been studied in the prevention of CIN.



Two hundred and two patients who underwent coronary angiography were included in the study. They were randomized into groups receiving the drug Na/K citrate per os and to the control group. Serum creatinine and glomerular filtration rate were determined in all patients immediately before coronary angiography, and 48 h after the procedure. CIN criteria were a creatinine increase of >25%, reduction in the glomerular filtration rate by >25%, or an increase in serum creatinine of >44 μmol/L. The incidence of CIN in the group receiving Na/K citrate was significantly lower when compared with the control group (4% compared with 20%, P = 0.0001). Patients who had a urine pH <6 had a more than ten-fold higher incidence of contrast nephropathy compared with patients whose urine pH was >6.



Alkalinization of urine using the Na/K citrate may reduce the incidence of CIN.
Psychobiological heterogeneity of familial and sporadic schizophrenia

Although schizophrenia is presumed to be heterogeneous, there has been limited success distinguishing familial from sporadic cases. We used psychobiological measures to examine heterogeneity, as they may be closer to neurobiology than symptoms. Smooth pursuit eye movement quality (SPEM) and dichotic listening (DL) tests to tones and words were used to assess hemispheric laterality asymmetry.



Forty-six research unit patients participated in assessments of family history (FH) and physiological measures. FH was categorized by three exclusive groups: FH-1 patients had a chronic schizophrenia-related psychosis in a first-degree relative, FH-2 had it in second-degree relative, and FH-3 had no family member with a reoccurrence.



Analysis of variance showed a significant group difference for SPEM and DL tones. SPEM was significantly worse in all three schizophrenia groups than for the normal comparison subjects. Among the schizophrenia groups, the nonfamilial group (FH-3) had the worst SPEM quality, FH-2 had intermediate quality, and FH-1 had the best quality. Conversely, only the nonfamilials (FH-3) had normal right hemispheric lateralization for tones, whereas familials did not, and FH-2 again had intermediate values. The lateralization quotient for DL words did not significantly differ among the groups.



SPEM was affected most in sporadic, not familial schizophrenia, whereas dichotic listening was most affected in familial schizophrenia. This double dissociation supports the utility of the familial/sporadic distinction and suggests that etiological factors in different forms of schizophrenia may impact principally on distinct neurobiological substrates, despite similar patient phenomenology.
Coherence treatment of postmenopausal osteoporosis with growth hormone and calcitonin

Fourteen women with postmenopausal osteoporosis, all having at least one vertebral crush fracture, were randomly assigned to two treatment arms, each lasting 24 months. The coherence treatment group (7 patients) was treated in the following sequence: human growth hormone (hGH) 7 IU subcutaneously daily for 2 months, followed by 3 months of salmon calcitonin (CT), 100 MRC units every other day. After a 3 month rest period, this sequence was repeated twice. The contrast group (7 patients) was treated intermittently with salmon CT given in the same time periods and at the same dose as in the coherence treatment group. Bone mass was measured every 4 months by neutron activation analysis for total body calcium (TBCa) and by single photon absorptiometry for bone mineral content (BMC) of the distal radius. Although there were no significant differences between the two groups (two-way ANOVA), the rate of change in TBCa in the coherence treatment group was significantly different from zero (F=3.8,P<.05) and was +2.3%/year. The increase in bone mass appeared to be sustained throughout the 2 year study, in contrast with previous studies where a plateau effect was observed with calcitonin given alone or continuously with growth hormone. No significant change was found in bone histomorphometric values measured before and after treatment in 4 patients from each group.
Competact, a fixed combination of pioglitazone and metformin, improves metabolic markers in type 2 diabetes patients with insufficient glycemic control by metformin alone--results from a post-marketing surveillance trial under daily routine conditions.

In patients with type 2 diabetes, glycemic control to target goals can only be achieved for a while by single-drug treatment. Antidiabetes therapy has to be adapted according to the individual course of the disease. This trial investigates the impact of Competact (Takeda Pharma, Aachen, Germany) (marketed as ActoplusMet in the United States)-a fixed combination of 850 mg of metformin with 15 mg of pioglitazone-for diabetes treatment in patients with insufficient glycemic control by metformin alone.



This observational drug monitoring trial was performed at 1,480 study sites in Germany, and 4,866 complete patient data sets were included into the final analyses. Mean +/- SD age was 60.8 +/- 9.6 years (2,171 women, 2,691 men; disease duration, 6.7 +/- 4.7 years; body mass index [BMI], 31.0 +/- 5.2 kg/m(2)). In total, 43.8% of the patients received lipid-lowering drugs (antihypertensive medication, 74.3%). Main inclusion criteria were type 2 diabetes, metformin monotherapy, and an initial hemoglobin A1c (HbA1c) value between 6.6% and 9.9%. Parameters of glycemic control (HbA1c, fasting blood glucose [FBG]), blood pressure (BP), inflammation (high-sensitivity C-reactive protein [hsCRP]), and lipid metabolism (total cholesterol, high-density lipoprotein [HDL]-cholesterol, non-HDL-cholesterol, and triglycerides) were collected at baseline and after 4 months.



All investigated parameters improved significantly (all P < 0.001) after 4 months of therapy with Competact (baseline vs. end point: systolic BP, 139.7 +/- 15.1 vs. 134.4 +/- 12.0 mm Hg; diastolic BP, 83.1 +/- 8.9 vs. 80.5 +/- 7.5 mm Hg; HbA1c, 7.8 +/- 1.0% vs. 7.0 +/- 0.8%; FBG, 9.0 +/- 2.6 vs. 7.0 +/- 1.7 mM; cholesterol, 5.7 +/- 1.1 mM vs. 5.3 +/- 0.9 mM; HDL-cholesterol, 1.2 +/- 0.4 mM vs. 1.3 +/- 0.4 mM; non-HDL-cholesterol, 4.5 +/- 1.2 mM vs. 4.0 +/- 0.9 mM; triglycerides, 2.5 +/- 1.0 mM vs. 2.1 +/- 0.8 mM; hsCRP, 3.2 +/- 2.6 mg/L vs. 2.7 +/- 2.3 mg/L). It is noteworthy that the BMI was not affected by Competact (31.0 +/- 5.2 kg/m(2) vs. 31.1 +/- 6.1 kg/m(2), P = 0.221).



These observational results, obtained from a non-selected patient population under daily routine conditions, show the beneficial effects of a pioglitazone/metformin combination for diabetes patients with insufficient glycemic control under daily routine conditions.
Efficacy of clindamycin/primaquine versus trimethoprim/sulfamethoxazole in primary treatment ofPneumocystis carinii pneumonia

Mild to moderately severePneumocystis carinii pneumonia in patients with AIDS was treated in a clinical trial with a combination regimen of primaquine and clindamycin, and the efficacy of this regimen was compared with that of the conventional treatment regimen of trimethoprim/sulfamethoxazole. The results revealed that primaquine/clindamycin appears to be an equally effective alternative to trimethoprim/sulfamethoxazole. The spectrum of side-effects was similar for the two regimens; side-effects occurred with equal frequency but appeared to be less severe in patients given primaquine/clindamycin. Because therapy with primaquine and clindamycin was limited to patients with mild to moderatePneumocystis carinii pneumonia, studies with this regimen in more severe cases are warranted.
Neuropeptide Y as an indicator of successful alterations in sympathetic nervous activity after renal sympathetic denervation

Renal sympathetic denervation (RSD) represents a safe and effective treatment option for certain patients with resistant hypertension and has been shown to decrease sympathetic activity. Neuropeptide Y (NPY) is a neurotransmitter that is co-released with norepinephrine and is up-regulated during increased sympathetic activity. The aim of the present study was to examine the effect of RSD on NPY and to analyze the association between changes in NPY levels and blood pressure reduction after RSD. A total of 150 consecutive patients (age 64.9 ± 10.2 years) from three clinical centers undergoing RSD were included in this study. Response to RSD was defined as an office systolic blood pressure (SBP) reduction of >10 mmHg 6 months after RSD. Venous blood samples for measurement of NPY were collected prior to and 6 months after RSD. BP and NPY levels were significantly reduced by 23/9 mmHg (p = 0.001/0.001) and 0.24 mg/dL (p < 0.01) 6 months after RSD. There was a significant correlation between baseline SBP- and RSD-related systolic BP reduction (r = −0.43; p < 0.001) and between serum NPY baseline values and NPY level changes (r = −0.52; p < 0.001) at the 6-month follow-up. The BP response to RSD (>10 mmHg) was associated with a significantly greater reduction in NPY level when compared with BP non-responders (p = 0.001). This study demonstrates an effect of RSD on serum NPY levels, a specific marker for sympathetic activity. The association between RSD-related changes in SBP and NPY levels provides further evidence of the effect of RSD on the sympathetic nervous system.
A novel flow cytometry-based cell capture platform for the detection, capture and molecular characterization of rare tumor cells in blood

Personalized cancer treatment relies on the accurate detection of actionable genomic aberrations in tumor cells. Circulating tumor cells (CTCs) could provide an alternative genetic resource for diagnosis; however, the technical difficulties in isolating and analyzing rare CTCs have limited progress to date. In this preclinical study, we aimed to develop an improved capture system for molecular characterization of CTCs based on a novel cell sorting technology. We developed a cell capture platform using On-chip Sort (On-Chip Biotechnologies), a novel bench-top cell sorter equipped with a disposable microfluidic chip. Spike-in experiments comprising a series of lung cancer cell lines with varying epithelial cell adhesion molecule (EpCAM) expression levels were conducted to assess the capture and purification efficiency of the platform. Samples were negatively enriched using anti-CD45-coated magnetic beads to remove white blood cells, followed by sample fixation and labeling. The enriched and labeled samples were then sorted by On-chip Sort based on cytokeratin, vimentin, and CD45 expression. Captured cells were immediately subjected to whole genome amplification followed by mutation analysis using deep targeted sequencing, and copy number analysis using quantitative polymerase chain reaction (qPCR). Spike-in experiments revealed an excellent overall mean capture rate of 70.9%. A 100% success rate in the detection of EGFR, KRAS and BRAF mutations from captured cells was achieved using pyrosequencing and deep sequencing. The mutant variant detection rates were markedly higher than those obtained with the CellSearch profile kit. qPCR analysis of amplified DNA demonstrated reproducible detection of copy number changes of the EGFR in captured tumor cells. Using a novel cell sorter, we established an efficient and convenient platform for the capture of CTCs. Results of a proof-of-principle preclinical study indicated that this platform has potential for the molecular characterization of captured CTCs from patients.
The effectiveness of a self-management occupational therapy intervention on activity performance in individuals with multiple sclerosis-related fatigue: a randomized-controlled trial.

to evaluate the effectiveness of an individual self-management occupational therapy intervention program (SMOoTh) versus relaxation on the performance of and satisfaction with relevant daily activities in individuals with multiple sclerosis (MS)-related fatigue. in a single-blind randomized-controlled trial, 31 patients with MS (SMOoTh: n=17, relaxation: n=14) were randomly allocated to three individual sessions focusing on pacing, prioritizing, ergonomics, and self-management (SMOoTh) or on stress management and relaxation (relaxation). Outcomes (blind assessor): Canadian Occupational Performance Measure (COPM) (primary), Modified Fatigue Impact Scale, Checklist Individual Strength and Short-Form Health Measure. COPM improved in the SMOoTh and relaxation group after the intervention and 3 months later (COPM performance: F=13.1, P=0.001 and COPM satisfaction: F=10.4, P=0.001); nonsignificant group differences showed a trend in favor of SMOoTh. Modified Fatigue Impact Scale, Checklist Individual Strength, and most of the Short-Form Health Measure subscales did not change. Clinically relevant changes in COPM performance scores were found in 71 and 27% of patients in the SMOoTh versus the relaxation group. Both interventions seem to be feasible approaches to improve performance of and satisfaction with relevant daily activities in people with MS, with a sustained effect after 3 months. Neither program altered change fatigue (impact) or quality of life. Future studies with larger sample sizes are needed.
A 3-arm randomized controlled trial on the effects of dance movement intervention and exercises on elderly with early dementia

Dementia is characterized by a progressive decline and deterioration of brain regions such as memory, spatial navigation and language, along with disturbances in daily functioning. Non-pharmacological interventions that offer a holistic approach by targeting cognitive functioning, prognosis and the psychological and social effects of dementia require rigorous investigation. The well-established benefits of physical activity for cognitive functioning and psychological support in dementia have been observed with dance-movement intervention. There is substantial evidence that dance-movement interventions provide emotional and social advantages. Thus, a randomized controlled trial (RCT) is planned to investigate the positive effects of a dance movement intervention, compared with mild physical exercise, on the physical and psychological well-being of elderly Chinese individuals with early dementia.



A 3-arm RCT with waitlist control design will be used in this study. Two hundred and one elderly participants with very mild to mild dementia will be screened and randomized into the following groups: (i) dance movement based intervention, (ii) stretching and exercise intervention and (iii) no intervention waitlist-control group. The two intervention groups will receive a 1-h intervention, twice a week, for 12 weeks. The participants will be assessed four times over the course of 12 months: baseline before randomization, post-intervention (3 months), 6 months from baseline and 12 months from baseline. The primary outcomes will be compared between assessment points and between groups on neuropsychiatric symptoms, psychosocial well-being and cognitive and daily functioning. Secondary outcomes will assess the changes in salivary cortisol levels and their relationships with the primary outcome measures.



This study will provide substantial evidence of the efficacy of a dance-movement-based intervention in slowing down dementia progression, due to its ability to act as a buffer against decline and improve areas affected by dementia. We also anticipate an association between cortisol levels and the outcome measures. The further development of this intervention into a structural program may be warranted for early psychosocial support among elderly populations.
Effect of short-term synbiotic treatment on plasma p-cresol levels in patients with chronic renal failure: a randomized clinical trial.

In patients with chronic kidney disease (CKD), alterations in gut microbiome are posited to be responsible for gastrointestinal symptoms and generation of p-cresol, a uremic toxin that has been associated with CKD progression and cardiovascular mortality. This pilot study investigated whether Probinul-neutro®, a synbiotic that normalizes intestinal microflora, may lower plasma p-cresol concentrations and reduce gastrointestinal symptoms in non-dialyzed CKD patients.



This was a double-blind, randomized placebo-controlled trial. Thirty patients on 3-4 CKD stages were randomized to receive either Probinul neutro® or placebo for 4 weeks. Total plasma p-cresol concentration was assessed at baseline, and 15 and 30 days after treatment start. At the same study times, ease and frequency of defecation, upper and lower abdominal pain, stool shape, borborygmi, and flatus were quantified by subjective assessment questionnaires. Compared to baseline total plasma p-cresol median concentrations on 15th and 30th day were significantly lower in patients receiving Probinul-neutro® (2.31 and 0.78 vs. 3.05 μg/ml, p < 0.05; n = 18); no changes of plasma p-cresol concentrations were recorded in placebo-treated patients. No significant changes in gastrointestinal symptoms were observed during the study both in Probinul-neutro®-treated and placebo-treated patients.



Probinul-neutro® lowered total plasma p-cresol concentrations but did not ameliorate gastrointestinal symptoms in non-dialyzed CKD patients. Because high plasma concentrations of p-cresol in early phases of CKD are predictive of progression to end-stage renal disease, the results of our study suggest that synbiotics deserve attention as possible tools to delay CKD progression towards end-stage renal disease (ESRD).
Protective effect of budesonide/formoterol compared with formoterol, salbutamol and placebo on repeated provocations with inhaled AMP in patients with asthma: a randomised, double-blind, cross-over study

The budesonide/formoterol combination is successfully used for fast relief of asthma symptoms in addition to its use as maintenance therapy. The temporarily increased corticosteroid dose during increasing inhaler use for symptom relief is likely to suppress any temporary increase in airway inflammation and may mitigate or prevent asthma exacerbations. The relative contribution of the budesonide and formoterol components to the improved asthma control is unclear.



The acute protective effect of inhaled budesonide was tested in a model of temporarily increased airway inflammation with repeated indirect airway challenges, mimicking an acute asthma exacerbation. A randomised, double-blind, cross-over study design was used. Asthmatic patients (n = 17, mean FEV1 95% of predicted) who previously demonstrated a > or = 30% fall in forced expiratory volume in 1 second (FEV1) after inhaling adenosine 5'-monophosphate (AMP), were challenged on four consecutive test days, with the same dose of AMP (at 09:00, 12:00 and 16:00 hours). Within 1 minute of the maximal AMP-induced bronchoconstriction at 09:00 hours, the patients inhaled one dose of either budesonide/formoterol (160/4.5 microg), formoterol (4.5 microg), salbutamol (2 x 100 microg) or placebo. The protective effects of the randomised treatments were assessed by serial lung function measurements over the test day.



In the AMP provocations at 3 and 7 hours after inhalation, the budesonide/formoterol combination provided a greater protective effect against AMP-induced bronchoconstriction compared with formoterol alone, salbutamol and placebo. In addition all three active treatments significantly increased FEV1 within 3 minutes of administration, at a time when inhaled AMP had induced the 30% fall in FEV1.



A single dose of budesonide/formoterol provided a greater protective effect against inhaled AMP-induced bronchoconstriction than formoterol alone, both at 3 and at 7 hours after inhalation. The acute protection against subsequent bronchoconstrictor stimuli such as inhaled AMP and the rapid reversal of airway obstruction supports the use of budesonide/formoterol for both relief and prevention in the treatment of asthma.
