Therapeutic massage of the neck and shoulders produces changes in peripheral blood flow when assessed with dynamic infrared thermography.

OBJECTIVE This study's objective was to determine the effect of therapeutic massage on peripheral blood flow utilizing dynamic infrared thermography in a constant temperature/humidity thermal chamber to assess noncontact skin temperature. DESIGN The design was a repeated-measures crossover experimental design; the independent variable was treatment condition (massage, light touch, control). SETTING The study setting was a university research laboratory. SUBJECTS Seventeen (17) healthy volunteers (8 males/9 females; age = 23.29 +/- 3.06) took part in the study. INTERVENTIONS One (1) 20-minute neck and shoulder therapeutic massage treatment was performed for each of the three treatment conditions. OUTCOME MEASURES The dependent variable was noncontact, mean skin temperature in 15 regions measured at 6 time points (pretest and 15, 25, 35, 45, and 60 minutes post-test) for each treatment condition. RESULTS The massage treatment produced significant elevations in temperature in five regions: anterior upper chest (p = 0.04), posterior neck (p = 0.0006), upper back (p = 0.0005), posterior right arm (p = 0.03), and middle back (p = 0.02). Massage therapy produced significant increases in temperature over time, compared to the other conditions, in the anterior upper chest, and posterior neck, upper back, right arm, and the middle back. Additionally, the temperatures remained above baseline levels after 60 minutes. Interestingly, the massage treatment produced significant temperature elevations in two nonmassaged areas posterior right arm and middle back. CONCLUSIONS These changes in temperature suggest corresponding changes in peripheral blood flow in the treated areas as well as in adjacent not-massaged areas. Moreover, the results suggest dynamic infrared thermography as a useful tool to measure noninvasive, noncontact changes in peripheral blood flow for massage therapy research.
Household optimism and overborrowing

We use Finnish householdâ€ level data from 1994 to 2013 to measure how often and what kind of forecast errors households make and how the errors are linked to the households' borrowing behavior and overindebtedness. We find that those households that make the largest optimistic forecast errors have greater debtâ€ toâ€ income ratios. They also are more likely to report that they suffer from excessive debt loads and have problems in coping with their bills. There are no such systematic effects for the households that make pessimistic forecast errors.
Contribution of Rating Scales to the Assessment of Executive Functions

Abstract Executive functions play a vital role in the everyday functioning of healthy individuals across the lifespan and have been implicated in a wide variety of clinical conditions. Historically, the assessment of executive functions in clinical and research settings relied on performance-based measures. A number of authors have argued, however, that such measures have limited ecological validity. In response to this limitation of performance-based measures, several rating scales have been developed that seek to gauge a person's or their knowledgeable informant's (e.g., parent or teacher) subjective view of executive functioning in everyday life. In this article we review evidence supporting the use of rating scales of executive function including profiles in clinical populations, biological correlates, relationships to relevant outcome measures such as academic performance, and correlations with performance-based measures. We conclude that performance-based and rating scale measures provide complementary information with respect to a child's executive functions, offering a more comprehension view than either approach alone.
Hospital‐acquired pneumonia in general wards of a Japanese tertiary hospital

Objective: Hospital‐acquired pneumonia (HAP) is an important nosocomial disorder because both its mortality and morbidity are high. The Japanese Respiratory Society (JRS) has proposed a new guideline for the diagnosis and treatment of HAP. Clinical investigations of HAP were conducted to assess the current status of HAP in accordance with this guideline.
Mutant superoxide dismutase 1-induced IL-1β accelerates ALS pathogenesis

ALS is a fatal motor neuron disease of adult onset. Neuroinflammation contributes to ALS disease progression; however, the inflammatory trigger remains unclear. We report that ALS–linked mutant superoxide dismutase 1 (SOD1) activates caspase-1 and IL-1β in microglia. Cytoplasmic accumulation of mutant SOD1 was sensed by an ASC containing inflammasome and antagonized by autophagy, limiting caspase-1–mediated inflammation. Notably, mutant SOD1 induced IL-1β correlated with amyloid-like misfolding and was independent of dismutase activity. Deficiency in caspase-1 or IL-1β or treatment with recombinant IL-1 receptor antagonist (IL-1RA) extended the lifespan of G93A-SOD1 transgenic mice and attenuated inflammatory pathology. These findings identify microglial IL-1β as a causative event of neuroinflammation and suggest IL-1 as a potential therapeutic target in ALS.
Cerebrospinal fluid T cells from multiple sclerosis patients recognize autologous Epstein-Barr virus-transformed B cells

The association between multiple sclerosis and Epstein-Barr virus infection could involve Epstein-Barr virus-specific T cells, provided that these T cells get access to the intrathecal compartment. We report that CD4+ T cells from the cerebrospinal fluid of six out of six multiple sclerosis patients, and four out of six patients with other neurological diseases, recognized autologous B cells transformed with Epstein-Barr virus. The cerebrospinal fluid T-cell responses were predominantly HLA-DR restricted. These T cells did not recognize B cells activated through stimulation of CD40 or the inducible autoantigen αB crystalline. These findings support that the immunological response to Epstein-Barr virus could contribute to the pathogenesis of multiple sclerosis.
The treatment of primary and metastatic renal cell carcinoma (RCC) with stereotactic body radiation therapy (SBRT) and stereotactic radiosurgery (SRS).

14572 Background: RCC is often regarded as a radio-resistant tumor. However, brain metastases from RCC have been successful treated with SRS. Therefore, metastases to extra-cranial sites may be treated with similar success using stereotactic body radiation therapy (SBRT), where image-guidance allows for the delivery of precise high dose radiation in a few fractions. We report our experience with SRS/SBRT in the management of primary and metastatic RCC. METHODS The image-guided Novalis radiation therapy system was used. Thirty patients with brain metastases were treated with SRS (16-22 Gy in a single fraction). Five of these patients underwent resection of their metastatic lesions after SRS and their pathology were reviewed. Twenty patients with extra-cranial metastatic lesions (orbits, head and neck, lung, mediatinum, sternum, clavicle, scapula, humerus, rib, spine, abdomen) and 2 patients with biopsy proven primary RCC (not surgical candidates), were treated with SBRT (24-32 Gy in 3-4 fractions over 1-2 weeks). All patients were immobilized in body cast and image-guidance was used for all fractions. 4D-CT was utilized in the treatment planning to assess tumor motion. RESULTS Of the 30 patients who received SRS to brain metastases, 25 showed decreasing or stable lesion size. Five patients showed an increase in size and underwent resection. Their pathology revealed necrosis in >99% of the specimen, with no viable RCC. Nineteen patients who received SBRT to extra-cranial metastases achieved symptom relief. One patient had local progression, yielding a local control rate of 95%. In the 2 patients with primary RCC, tumor size remained unchanged but their pain improved, and their renal function was unchanged post SBRT. There was no significant treatment related side-effect. CONCLUSIONS Precise high dose radiation can cause significant tumor cell death in "radio-resistant" metastases from RCC. It also offers excellent local control and symptom palliation, without significant toxicity. Therefore, SBRT may represent a novel non-invasive, nephron-sparing option for the treatment of primary RCC as well as extra-cranial metastatic RCC. A prospective clinical trial using SBRT for primary and metastatic RCC is on-going. No significant financial relationships to disclose.
Maintenance of cell fates through acetylated histone and the histone variant H2A.z in C. elegans

Maintenance of cell fates is essential for the development and homeostasis of multicellular organisms and involves the preservation of the expression status of selector genes that control many target genes. Epigenetic marks have pivotal roles in the maintenance of gene expression status, as occurs with methylation on lysine 27 of histone H3 (H3K27me) for Hox gene regulation. In contrast, because the levels of histone acetylation decrease during the mitotic phase, acetylated histone has not been believed to contribute to the maintenance of cell fates. Because members of the bromodomain and extra terminal (BET) family bind to acetylated histones localized on mitotic chromosomes, it is possible that they may regulate the transcriptional status of genes throughout the cell cycle. In this commentary, we discuss the recent analyses of C. elegans BET family protein BET-1, which contributes to the maintenance of cell fates through the histone H2A variant HTZ-1/H2A.z. This mechanism represses transcription of selector genes in the genomic region where lysine 27 of histone H3 (H3K27) is demethylated by histone demethylase UTX-1. We discuss the possibility that BET-1 and HTZ-1 maintain the poised state of RNA polymerase II in the cell such that it is ready to respond to differentiation signals.
Metabolite Levels in Paediatric Brain Tumours Correlate with Histological Features

Aims: Metabolite levels can be measured non-invasively using in vivo 1H magnetic resonance spectroscopy (MRS). These tumour metabolite profiles are highly characteristic for tumour type in childhood brain tumours; however, the relationship between metabolite values and conventional histopathological characteristics has not yet been fully established. This study systematically tests the relationship between metabolite levels detected by MRS and specific histological features in a range of paediatric brain tumours. Methods: Single-voxel MRS was performed routinely in children with brain tumours along with the clinical imaging prior to treatment. Metabolites were quantified using LCModel. Histological features were assessed semi-quantitatively for 27 children on H&E and immunostained slides, blind to the metabolite values. Statistical analysis included 2-tailed independent-samples t tests and 2-tailed Spearman rank correlation tests. Results: Ki67, cellular atypia, and mitosis correlated positively with choline metabolites, and phosphocholine in particular. Apoptosis and necrosis were both associated with lipid levels, with the relationship dependent on the use of long or short echo time MRS acquisitions. Neuronal components correlated negatively and glial components positively with N-acetyl-aspartate. Glial components correlated positively with myoinositol. Conclusion: Metabolite levels in children's brain tumours measured by MRS are closely associated with key histological features routinely assessed by histopathologists in the diagnostic process. This further elucidates our understanding of this important non-invasive diagnostic tool and strengthens our understanding of the relationship between metabolites and histological features.
Effects of Bariatric Surgery on Early Myocardial Alterations in Adult Severely Obese Subjects

Objective: Aim of this study was to investigate the effect of weight loss on structural and functional myocardial alterations in severely obese subjects treated with bariatric surgery. Patients and Methods: Thirteen severely obese patients (2 males and 11 females) were enrolled in the study. All subjects underwent conventional 2D color Doppler echocardiography. The new ultrasonic techniques used were: (a) integrated backscatter for the analysis of myocardial reflectivity, referred to pericardial interface as expression of myocardial structure (increase in collagen content) and of cyclic variation index as expression of intrinsic myocardial contractility and (b) color Doppler myocardial imaging (CDMI) for the analysis of strain and strain rate (myocardial deformability). All subjects underwent bariatric surgery and were resubmitted to echocardiographic and biochemical examination 6–24 months after surgery. Results: The main finding of the present study was a quite complete normalization of myocardial functional and structural alterations after weight loss. In particular, the cyclic variation index at septum level improved from 14.6 ± 7.0 before to 25.7 ± 11.2 (means ± SD) after surgery (controls: 36.2 ± 9.1). Mean reflectivity at septum level significantly decreased from 55.8 ± 9.5 to 46.5 ± 8.8 (controls: 43.0 ± 8.0). Also, the strain at septum level significantly improved after surgery (from –11.9 ± 3.2 to –20.4 ± 5.3; controls: –23.4 ± 9). Conclusion: This study establishes: (a) the utility of new ultrasonic techniques to detect very early structural and functional myocardial alterations in severely obese patients, and (b) the regression of these subclinical abnormalities after weight loss achieved by bariatric surgery.
Regulation of apolipoprotein E gene expression after injury of the rat sciatic nerve

The expression of apolipoprotein E (apo E) is dramatically increased following peripheral nerve injury. This increased expression has been postulated to be negatively influenced by unknown mechanisms during subsequent axonal regeneration (Muller et al.: Science 228:499–501, 1985). The present study investigates the role of the regenerating axon in regulating apo E gene expression in two experimental paradigms which permit or prevent axonal regeneration in the adult rat sciatic nerve—the crush or permanent transection injuries. The nerves in these two models undergo axonal degeneration, demyelination, and Schwann cell proliferation; however, subsequent axonal regeneration and remyelination occur only in the distal segment of the crush‐injured and not in the permanently transected nerve. The steady‐state levels of apo E mRNA in both models increase sharply between 1 and 4 days and reach a maximum level at 12–14 days, which did not change significantly between 14 and 35 days after injury. No significant difference is observed in the steady‐state levels of apo E mRNA between the crushed and permanently transected nerves as a function of time after injury. The steady‐state protein level of apo E in the endoneurial segments initially increases, peaks at 14–21 days, and then decreases between 35 and 60 days after injury in both models. In contrast, the rate of newly translated and secreted apo E significantly increases by fourfold (P < 0.005) between 35 and 60 days after permanent transection whereas it does not significantly differ at these times after crush injury. The increased rate of translation and secretion of apo E after transection compared to the constant rate observed after crush injury, together with the comparable steady‐state levels of apo E mRNA and protein in both models, suggests translational or post‐translational control, but not transcriptional and/or post‐transcriptional control, by the regenerating axons. Furthermore, the increasing rate of biosynthesis and secretion of apo E after permanent transection concomitant with the decreasing steady‐state levels of the protein suggests that apo E is either removed from the endoneurium or subsequently utilized or degraded by mechanisms that are independent from nerve regeneration.
Variations in plasma concentrations of tamoxifen metabolites and the effects of genetic polymorphisms on tamoxifen metabolism in Korean patients with breast cancer

Inter-individual variation in tamoxifen metabolism in breast cancer patients is caused by various genetic and clinical factors. We measured the plasma concentrations of tamoxifen and its metabolites and investigated genetic polymorphisms influencing those concentrations. We measured the concentrations of tamoxifen, endoxifen, N-desmethyltamoxifen (NDM), and 4-hydroxytamoxifen (4-OH tamoxifen) in 550 plasma specimens from 281 breast cancer patients treated with tamoxifen. Duplicate or triplicate specimens were obtained from 179 patients at 3-month intervals. In 80 patients, genotyping for tamoxifen metabolizing enzymes was performed using the DMET Plus array and long-range PCR. Plasma concentrations of tamoxifen and its metabolites showed wide variations among patients. The following genetic polymorphisms were associated with the plasma concentrations when body mass index and tamoxifen concentrations were considered as co-variables: CYP1A2 -2467delT, CYP2B6 genotype, CYP2D6 activity score (AS), and FMO3 441C>T. CYP2D6 AS and three variants in the SULT1E1 gene showed correlation with ratios of tamoxifen metabolites. CYP2D6 AS was the only variable that showed associations with both metabolite concentration and ratio: endoxifen (P < 0.001), NDM (P < 0.001), endoxifen/NDM (P < 0.001), NDM/tamoxifen (P < 0.001), and 4-OH tamoxifen/tamoxifen (P = 0.005). Serial measurements of 448 plasma concentrations in 179 patients at 3-month intervals showed wide intra-individual variation. Our study showed that genetic polymorphisms can in part determine the baseline concentrations of tamoxifen and its metabolites. However, marked intra-individual variations during follow-up monitoring were observed, and this could not be explained by genotype. Therefore, serial measurements of tamoxifen and its metabolites would be helpful in monitoring in vivo tamoxifen metabolic status.
Association Between Low IQ Scores and Early Mortality in Men and Women: Evidence From a Population-Based Cohort Study.

Lower (versus higher) IQ scores have been shown to increase the risk of early mortality, however, the underlying mechanisms are poorly understood and previous studies underrepresent individuals with intellectual disability (ID) and women. This study followed one third of all senior-year students (approximately aged 17) attending public high school in Wisconsin, U.S. in 1957 (n = 10,317) until 2011. Men and women with the lowest IQ test scores (i.e., IQ scores ≤ 85) had increased rates of mortality compared to people with the highest IQ test scores, particularly for cardiovascular disease. Importantly, when educational attainment was held constant, people with lower IQ test scores did not have higher mortality by age 70 than people with higher IQ test scores. Individuals with lower IQ test scores likely experience multiple disadvantages throughout life that contribute to increased risk of early mortality.
Efficacy of a Methylphenidate Transdermal System Versus t.i.d. Methylphenidate in a Laboratory Setting

Objective: To test the efficacy and tolerability of the methylphenidate transdermal formulation (MTS) against immediate-release methylphenidate (IR MPH) and placebo in a 12-hr analog classroom setting. Method: A total of nine boys ages 6 to 9 years, medicated with MPH for ADHD, complete a within-subject, double-blind study. For the purpose of the study, the boys are administered a dose of 20 cm2 MTS, a matched dose of IR MPH 10 mg TID, and placebo. ADHD symptoms and frequency counts of classroom rule violations and the number of math problems completed are assessed hourly, during three consecutive analog classroom sessions. Results: Findings show that, across measures and throughout the day, both treatments significantly differentiated from placebo (p < .05) but not from each other. It is also observed that the MTS produced more consistent results across the day but had a delayed onset versus IR MPH. Both medications are well tolerated with only mild reductions in sleep onset. Conclusion: The MTS demonstrates comparable efficacy and tolerability to TID IR MPH.
A prospective study on the use of leucocyte-filters in reducing blood transfusion reactions in multi-transfused thalassemic children.

Two hundred and eleven blood transfusions were administered to 26 multi-transfused thalassemic children (aged 9 months-13 years) over a 6-month period. Eighteen children were receiving buffy coat-poor packed red cells (PRC) prepared by centrifuge while 8 children received filtered blood through a leucocyte-filter (Sepacell R-500A). Transfusion reactions occurred in 8.5% (n = 18) of transfusions and in 42.3% (n = 11) of patients. 11.9% (n = 16) and 2.6% (n = 2) of reactions occurred in 50% (n = 9) and 25% (n = 2) of patients receiving buffy coat-poor PRC and filtered blood respectively. Transfusion reactions in toto were significantly reduced in the group receiving filtered blood (p < 0.05). However, febrile reaction alone was not significantly reduced (p > 0.1). The median onset and duration of reaction were 2 hours (range 10 minutes-18 hours) and 4 hours (range 1/2-24 hours) respectively. 72.2% (n = 13) of the reactions occurred occurred during transfusion. 88.8% (n = 16) of the reactions caused only one symptom. 19.2% (n = 5) of all patients had recurrent reactions, all of them receiving buffy coat-poor PRC. The commonest clinical manifestation was fever (n = 7), followed by urticaria (n = 5) and petechial rash (n = 2). The outcome was good, with no patient experiencing symptoms exceeding 24 hours. Only 0.9% (n = 2) of the transfusions were discontinued.
Cytokines in pancreatic carcinoma

Cytokines have been implicated in diverse processes that are relevant to pancreatic carcinoma, including cachexia, asthenia, and tumor growth. The objective of this study was to examine the association between serum levels of proinflammatory and antiinflammatory or angiogenic cytokines and the outcomes of patients with pancreatic carcinoma.
Interactive and delayed effects of pyridostigmine and physical stress on biochemical and histological changes in peripheral tissues of mice

Gulf War veterans were taking pyridostigmine orally against possible exposure to nerve agents as well as being under physical stress. This study was designed to investigate the delayed effects of pyridostigmine and treadmill exercise on cholinesterase activity, lipid peroxidation and histology of peripheral tissues of mice. Male NIH Swiss mice were divided into four groups of 15 animals each and treated as follows: sedentary control; exercise training for 10 weeks; pyridostigmine (1.2 mg kg−1, p.o.) for 2 weeks during weeks 5 and 6; and pyridostigmine plus exercise training. The mice were sacrificed 24 h after the last exercise, and blood, triceps muscle and sciatic nerve were isolated and analyzed. The group treated with pyridostigmine alone showed decreased plasma butyrylcholinesterase (BChE) activity (87% of control), whereas pyridostigmine plus exercise significantly decreased the BChE activity (79% of control), indicating an interactive effect of the combination. Acetylcholinesterase (AChE) activity did not alter significantly in red blood cells, platelets or sciatic nerve with either of the treatments. However, AChE activity in triceps muscle decreased significantly (78% of control) in the group treated with pyridostigmine plus exercise. Creatine phosphokinase activity in plasma increased slightly (compared to control, pyridostigmine or exercise group) in mice treated with pyridostigmine plus exercise, which may be indicative of perturbation in the integrity of the skeletal muscle due to combination. However, there were no obvious histological abnormalities in the triceps muscle detected between experimental and control groups. Interaction of pyridostigmine and exercise significantly increased the concentration of the end product of lipid peroxidation (malondialdehyde) (124% of control) in triceps muscle, indicating an oxidative stress response of the combination. These results indicate that physical stress enhanced the delayed toxic effects of a subchronic oral dose of pyridostigmine primarily in the skeletal muscle of mice.
