    A 64-year-old woman underwent reduced-intensity conditioning cord blood transplantation (RIC-CBT) for refractory acute myeloid leukemia (AML). A 6/6 antigen-level HLA-identical cord blood from a male infant was transfused. After successful engraftment with complete donor chimerism, the patient developed mixed chimera (XX 8.8%) on day 82. Tapering of tacrolimus was started on day 96. Bone marrow chimerism analysis showed a decreasing recipient cell population (XX 2.2%) on day 117 and tacrolimus was discontinued with no clinical signs of GVHD on day 123. However, pancytopenia with agranulocytosis was detected on day 138. She was diagnosed as having secondary graft failure associated with Coombs-positive immune hemolytic anemia and immune thrombocytopenia (ITP). At the same time, the percentage of recipient T cell chimerism in peripheral blood was about 50% and the B cell population showed lambda light chain restriction. On day 180, she received a second RIC-CBT due to lack of improvement of agranulocytosis. A single dose of rituximab was administered on day - 11 before the second CBT to eliminate the activated B cells. Prompt neutrophil engraftment was achieved and both hemolytic anemia and ITP also showed resolution. She is currently well (30 months after the second CBT), showing normal blood cell counts and complete second donor chimerism of marrow cells.

    Objective To examine the possibility that maintenance cognitive behavior therapy (M–CBT) may improve the likelihood of sustained improvement and reduced relapse in a multi-site randomized controlled clinical trial of patients who met criteria for panic disorder with or without agoraphobia. Method Participants were all patients (N = 379) who first began an open trial of acute-phase CBT. Patients completing and responding to acute-phase treatment were randomized to receive either nine monthly sessions of M-CBT (n = 79) or assessment only (n = 78) and were then followed for an additional 12 months without treatment. Results M–CBT produced significantly lower relapse rates (5.2%) and reduced work and social impairment compared to the assessment only condition (18.4%) at a 21-month follow-up (MFU). Multivariate Cox proportional hazards models showed that residual symptoms of agoraphobia at the end of acute-phase treatment were independently predictive of time to relapse during 21-MFU (HR = 1.15, p < .01). Conclusions M–CBT aimed at reinforcing acute treatment gains to prevent relapse and offset disorder recurrence may improve long-term outcome in PD/A. PMID:23127290

    Polymyositis and dermatomyositis (PM/DM) are representative inflammatory muscle diseases. In treatment of PM/DM, drug therapies are cardinal but rehabilitation may be another option. Since muscles with PM/DM are fragile for muscle exercise, rehabilitation has been recommended mainly in chronic phase. Some researchers considered that rehabilitation for PM/DM patients in acute phase may improve their functional prognosis without major sideeffect. However, there are controversies about rehabilitation for PM/DM patients from acute phase. To consider advisability, I reviewed literatures concerning rehabilitation for PM/DM patients in acute phase.

    Objectives Many youth develop complex trauma, which includes regulation problems in the domains of affect, attachment, behavior, biology, cognition, and perception. Therapists often request strategies for using evidence-based treatments (EBTs) for this population. This article describes practical strategies for applying Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth with complex trauma. Methods TF-CBT treatment phases are described and modifications of timing, proportionality and application are described for youth with complex trauma. Practical applications include a) dedicating proportionally more of the model to the TF-CBT coping skills phase; b) implementing the TF-CBT Safety component early and often as needed throughout treatment; c) titrating gradual exposure more slowly as needed by individual youth; d) incorporating unifying trauma themes throughout treatment; and e) when indicated, extending the TF-CBT treatment consolidation and closure phase to include traumatic grief components and to generalize ongoing safety and trust. Results Recent data from youth with complex trauma support the use of the above TF-CBT strategies to successfully treat these youth. Conclusions The above practical strategies can be incorporated into TF-CBT to effectively treat youth with complex trauma. Practice implications Practical strategies include providing a longer coping skills phase which incorporates safety and appropriate gradual exposure; including relevant unifying themes; and allowing for an adequate treatment closure phase to enhance ongoing trust and safety. Through these strategies therapists can successfully apply TF-CBT for youth with complex trauma. PMID:22749612

    An acute-phase response (APR), manifested as an increase of acute-phase proteins has been shown in major depression. Panic disorder (PD) may share some aetiopathogenic mechanisms with depression, but APR has not been studied in this disorder. Forty-one panic patients in the first stages of their illness were compared with 32 healthy subjects of comparable sex, age, and body mass index. Clinical diagnosis was established with the mini international neuropsychiatric interview, and severity with the panic disorder severity scale and the CGI scale. Laboratory determinations included four acute phase proteins (APPs) [albumin, gammaglobulins, fibrinogen, C-reactive-protein (CRP)] and basal cortisol level. Patients were studied after 8-wk follow-up taking selective serotonin reuptake inhibitors (SSRIs) to assess the evolution of the APPs. Gammaglobulin levels were lower, and both cortisol and CRP levels were higher in PD patients than in controls. APP did not differ between patients with or without agoraphobia. At follow-up, patients who responded to SSRIs presented a decrease in albumin levels, and a trend towards a decrease in cortisol and CRP compared with levels at intake. The conclusions of this study are that there is an APR in patients suffering from PD, and this APR tends to diminish after a successful treatment with SSRIs. PMID:15927091

    2015-01-01

    Acute phase proteins are a class of proteins whose plasma concentration increase (positive acute phase proteins) or decrease (negative acute phase proteins) in response to inflammation. This response is called as the acute phase reaction, also called as acute phase response, which occurs approximately 90 minutes after the onset of a systemic inflammatory reaction. In Periodontitis endotoxins released from gram negative organisms present in the sub gingival plaque samples interact with Toll- like receptors (TLR) that are expressed on the surface of Polymorphonuclear leucocytes (PMNs) and monocytes which are in abundance in periodontal inflammation. The complex formed due to interaction of Endotoxins and TLR activates the Signal transduction pathway in both innate and adaptive immunity resulting in production of Cytokines that co- ordinate the local and systemic inflammatory response. The pro inflammatory cytokines originating at the diseased site activates the liver cells to produce acute phase proteins as a part of non specific response. The production of Acute phase proteins is regulated to a great extent by Cytokines such as IL-1, IL-6, IL-8, TNF-α and to a lesser extent by Glucocorticoid hormones. These proteins bind to bacteria leading to activation of complement proteins that destroys pathogenic organisms. Studies have shown that levels of acute phase proteins are increased in otherwise healthy adults with poor periodontal status. This article highlights about the synthesis, structure, types and function of acute phase proteins and the associated relation of acute phase proteins in Periodontitis. PMID:26674303

    We present our experience with 21 patients of pemphigus vulgaris seen over a period of 10 years managed in service hospitals during acute phase of the disease. Age groups of patients ranged from 25-45 years. Eighteen (85.7%) were young adults, 30-40 years of age. Fifteen (71.4%) were men and 6 (28.6%) were women. All the cases were hospitalized in ICU, till the acute phase of the disease subsided. Complete hematological profile, urinalysis, serum biochemistry and repeated bacterial cultures from the skin were carried out in all patients at the time of admission and thereafter weekly. The treatment comprised of potassium permanganate lotion bath (1:10,000) and 1 framycetin gauze dressing of the denuded areas, maintenance of fluid and electrolyte balance. All suspected infections and septicemia were treated with appropriate antibiotics. The corticosteroids were usually administered as a single dose of prednisolone 1 mg/kg/day. Cyclophosphamide was given at an initial dose of 50 mg/day and the dose was escalated to 100 mg/day. Once the bulk of the lesions were healed, the dose of corticosteroids was gradually lowered by approximately 50% every two weeks and cyclophosphamide was continued till patients were symptom-free. Out of 21 patients receiving corticosteroids, cyclophosphamide and other supportive therapy, 20 (95%) had undergone clinical resolution of the disease. During follow up study 15 (71.4%) patients remained symptom-free and undergone clinical remission. Five patients (23.8%) had relapse, out of which 4 (19%) remained symptom free, after subsequent treatment. There was one death (4.7%) in our study.

    Depression and substance use, the most common comorbidities with HIV, are both associated with poor treatment outcomes and accelerated HIV disease progression. Though previous research has demonstrated short-term and follow-up success for cognitive behavioral therapy for adherence and depression (CBT-AD) on depression outcomes among patients with HIV in care and among patients with HIV in active substance abuse treatment for injection drug use (IDU), there is little information regarding possible moderating effects of active use versus abstinence on depression treatment gains. The present study aimed to examine recent substance use at treatment initiation as a moderator of the acute and maintenance effects of CBT-AD on depression. We used data from a two-arm, randomized controlled trial (N = 89) comparing CBT-AD to enhanced treatment as usual in individuals in treatment for IDU. To test whether depression at time of presentation affected outcomes, repeated-measures ANOVAs were conducted for two time frames: (1) acute phase (baseline to post-treatment) (acute) and (2) maintenance phase (baseline to 12-month follow-up). To further examine maintenance of gains, we additionally looked at post-treatment to 12-month follow-up. Depression scores derived from the clinical global impression for severity and the Montgomery-Asberg depression rating scale (MADRS) served as the primary outcome variables. Acute (baseline post treatment) moderation effects were found for those patients endorsing active drug use at baseline in the CBT-AD condition, who demonstrated the greatest reductions in MADRS scores at post-treatment (F[1,76] = 6.78, p = .01) and follow-up (F[1,61] = 5.46, p = .023). Baseline substance use did not moderate differences from post-treatment to 12-month follow-up as depression treatment gains that occurred acutely from baseline to post-treatment were maintained across both patients engaged in substance use and abstainers. We conclude that CBT

    Objective Generalized anxiety disorder (GAD) is a prevalent psychiatric condition in older adults with deleterious effects on health and cognition. Although selective serotonin reuptake inhibitor (SSRI) medications have some efficacy as acute treatments for geriatric GAD, incomplete response is the most common outcome of monotherapy. We therefore developed a novel sequential treatment strategy, using personalized, modular cognitive-behavioral therapy (mCBT) to augment SSRI medication. Method In an open label pilot study (N =10), subjects received a sequenced trial of 12 weeks of escitalopram followed by 16 weeks of escitalopram augmented with mCBT. We also examined the maintenance effects of mCBT over a 28-week follow-up period following drug discontinuation and termination of psychotherapy. Results Results suggest that (1) adding mCBT to escitalopram significantly reduced anxiety symptoms and pathological worry, resulting in full remission for most patients and (2) some patients maintained response after all treatments were withdrawn. Conclusion Findings suggest that mCBT may be an effective augmentation strategy when added to SSRI medication and provide limited support for the long-term benefit of mCBT after discontinuation of pharmacotherapy.

The electrolyte imbalance is frequently detected in critical ill patients. It is reported that the extreme abnormalities of ionized calcium concentrations are independent predictors of mortality. In addition, from clinical database MIMIC-Ⅱ,calcium supplementation improves clinical outcome in intensive care unit patients. Although metabolic syndrome; lifestyle-related disease, is a chronic disease, the possibility of falling into acute disease by having it becomes very high and improvement of electrolyte imbalance, especially hypocalcaemia is expected to effective on clinical outcome.

    Objective To evaluate cognitive behavioral therapy to enhance medication adherence and reduce depression (CBT-AD) in individuals with HIV. Design A two arm, randomized, controlled, cross-over trial comparing CBT-AD, to enhanced treatment as usual only (ETAU). ETAU, which both groups received, included a single-session intervention for adherence and a letter to the patient’s provider documenting her or his continued depression. The intervention group also received 10 to 12 sessions of CBT-AD. Main Outcome Measures Adherence to antiretroviral therapy as assessed by Medication Event Monitoring Systems (MEMs) and depression as assessed by blinded structured evaluation. Results At the acute outcome assessment (3-months), those who received CBT-AD evidenced significantly greater improvements in medication adherence and depression relative to the comparison group. Those who were originally assigned to the comparison group who chose to cross over to CBT-AD showed similar improvements in both depression and adherence outcomes. Treatment gains for those in the intervention group were generally maintained at 6 and 12-month follow-up assessments. By the end of the follow-up period, those originally assigned CBT-AD demonstrated improvements in plasma HIV RNA concentrations, though these differences did not emerge before the cross-over, and hence there were not between-group differences. Conclusions CBT-AD is a potentially efficacious approach for individuals with HIV struggling with depression and adherence. Replication and extension in larger efficacy trials are needed.

    2010-08-01

    Despite its acute efficacy for the treatment of panic disorder, benzodiazepines (BZs) are associated with a withdrawal syndrome that closely mimics anxiety sensations, leading to difficulty with treatment discontinuation and often disorder relapse. An exposure-based cognitive-behavioral treatment for BZ discontinuation, Panic Control Treatment for BZ Discontinuation (CBT) targets the fear of these sensations and has demonstrated efficacy in preventing disorder relapse and facilitating successful BZ discontinuation among patients with panic disorder. In this randomized controlled trial, CBT was compared to taper alone and a taper plus a relaxation condition to control for the effect of therapist contact and support among 47 patients with panic disorder seeking taper from BZs. Based on the primary outcome of successful discontinuation of BZ use, results indicate that adjunctive CBT provided additive benefits above both taper alone and taper plus relaxation, with consistently medium and large effect sizes over time that reached significance at the six month follow-up evaluation. The efficacy of CBT relative to either of the other taper conditions reflected very large and significant effect sizes at that time. These findings suggest that CBT provides specific efficacy for the successful discontinuation from BZs, even when controlling for therapist contact and relaxation training.

    We evaluated the acute phase protein response in capybaras (Hydrochoerus hydrochaeris). Three animal groups were used: 1) healthy animals (n=30), 2) a group in which experimental inflammation with turpentine was induced (n=6), and 3) a group affected with sarcoptic scabies (n=14) in which 10 animals were treated with ivermectin. Haptoglobin (Hp), acid-soluble glycoprotein (ASG) and albumin were analyzed in all animals. In those treated with turpentine, Hp reached its maximum value at 2 wk with a 2.7-fold increase, whereas ASG increased 1.75-fold and albumin decreased 0.87-fold 1 wk after the induction of inflammation. Capybaras affected with sarcoptic scabies presented increases in Hp and ASG of 4.98- and 3.18-fold, respectively, and a 0.87-fold decrease in albumin, compared with healthy animals. Haptoglobin and ASG can be considered as moderate, positive acute phase proteins in capybaras because they showed less than 10-fold increases after an inflammatory process and reached their peak concentrations 1 wk after the induction of inflammation. Conversely, albumin can be considered a negative acute phase protein in capybaras because it showed a reduction in concentration after inflammatory stimulus.

    Background and Purpose We report a novel finding of caloric conversion from normal responses into unilateral paresis during the acute phase of vestibular neuritis (VN). Methods We recruited 893 patients with a diagnosis of VN at Dizziness Clinic of Seoul National University Bundang Hospital from 2003 to 2014 after excluding 28 patients with isolated inferior divisional VN (n=14) and those without follow-up tests despite normal caloric responses initially (n=14). We retrospectively analyzed the neurotological findings in four (0.5%) of the patients who showed a conversion from initially normal caloric responses into unilateral paresis during the acute phase. Results In those four patients, the initial caloric tests were performed within 2 days of symptom onset, and conversion into unilateral caloric paresis was documented 1–4 days later. The clinical and laboratory findings during the initial evaluation were consistent with VN in all four patients except for normal findings in bedside head impulse tests in one of them. Conclusions Normal findings in caloric tests should be interpreted with caution during the acute phase of suspected VN. Follow-up evaluation should be considered when the findings of the initial caloric test are normal, but VN remains the most plausible diagnosis. PMID:26932259

    Cognitive-behavioral therapy (CBT) is an efficacious first-line therapy for patients with major depressive disorder (MDD). Due to the limited accessibility of CBT, long wait lists result in delayed treatment, which may affect treatment outcomes. The goal of this pilot study was to obtain preliminary data from a randomized controlled trial to determine whether delayed CBT reduces the effectiveness of the therapy compared to immediate CBT in patients with MDD receiving pharmacotherapy. Patients were randomized to receive immediate CBT (n=18) or to begin CBT after 6 months (n=20) and received 14 weekly sessions, followed by two additional booster sessions. During the active treatment months, patients in the immediate group demonstrated reductions in scores on the Beck Depression Inventory II (BDI-II) that were similar to those in the delayed CBT group. However, when the analysis was performed using only data from patients in the delayed group who were still in a depressive episode, there was an overall greater decrease in BDI-II scores in the immediate group vs. the delayed group over the active treatment months, but not specifically at the 6-month endpoint. These findings suggest delays in depression treatment, similar to what occurs with real-world wait list times, may not have a significant impact on the effectiveness of CBT in patients who are already receiving treatment as usual. However, such delays may affect the effectiveness of CBT in those patients who remain depressed during the time delay. A larger trial is necessary to confirm these findings.

    The half-lives of typical acute phase proteins in rats and beagle dogs during acute inflammation were investigated. Acute inflammation was induced by injection of turpentine oil in rats and administration of indomethacin in beagle dogs. Serum concentrations of α2-macroglobulin (α2M) and C-reactive protein (CRP) were measured by enzyme-linked immunosorbent assay and α1-acid glycoprotein (AAG) was measured by single radial immunodiffusion. Half-life was calculated as 0.693/elimination rate constant (K). The mean half-lives in the terminal elimination phase of α2M and AAG were 68.1 and 164.8 h, respectively. The half-life of AAG was significantly longer than that of α2M. Mean half-lives in the terminal elimination phase of CRP and AAG were 161.9 and 304.4 h, respectively. The half-life of AAG was significantly longer than that of CRP in beagle dogs. No significant differences in the half-life of AAG were observed between rats and beagle dogs. Furthermore, serum concentrations in the terminal elimination phase could be simulated with the K data acquired in this study.

    2014-01-01

    Acute pancreatitis (AP) is a potentially life-threatening disease with a wide spectrum of severity. The overall mortality of AP is approximately 5%. According to the revised Atlanta classification system, AP can be classified as mild, moderate, or severe. Severe AP often takes a clinical course with two phases, an early and a late phase, which should both be considered separately. In this review article, we first discuss general aspects of AP, including incidence, pathophysiology, etiology, and grading of severity, then focus on the assessment of patients with suspected AP, including diagnosis and risk stratification, followed by the management of AP during the early phase, with special emphasis on fluid therapy, pain management, nutrition, and antibiotic prophylaxis.

    There is currently lack of information on the changes of acute phase proteins (APP) and antioxidant markers and their clinical relevance as treatment response indicators in canine monocytic ehrlichiosis (CME). The objective of this study was to investigate the patterns of C-reactive protein (CRP), haptoglobin (Hp), ferritin and paraoxonase-1 (PON-1) during treatment of dogs with acute CME with rifampicin. Blood serum samples from ten Beagle dogs with experimental acute CME were retrospectively examined. Five dogs (Group A) were treated with rifampicin (10mg/Kg/24h), per os, for 3 weeks and 5 dogs (Group B) received no treatment (infected controls). Two Beagle dogs served as uninfected controls. Blood serum samples were serially examined prior to Ehrlichia canis inoculation and on post-inoculation days 14, 21, 28, 35 and 42. Significant changes of CRP, Hp, ferritin and PON-1 values were found in the majority of infected dogs. However, their concentrations did not differ between the two groups during the treatment observation period. The results of this study indicate that although several APP and PON-1 tend to significantly change in the majority of dogs with acute CME, they were of limited clinical relevance as treatment response indicators in this experimental setting.

    Experimental inflammation in rats led to a sevenfold increase in serum levels of alpha 1 acute-phase globulin. This increase is correlated with elevated levels of translatable mRNA for alpha 1 acute-phase globulin in the liver. Biosynthesis and secretion of alpha 1 acute-phase globulin were studied in rat hepatocyte primary cultures. An intracellular form of alpha 1 acute-phase globulin with an apparent relative molecular mass of 63 500 and a secreted form of 68 000 were found. The intracellular form of alpha 1 acute-phase globulin could be deglycosylated by endoglucosaminidase H treatment indicating that its oligosaccharide chains were of the high-mannose type. The secreted form of alpha 1 acute-phase globulin was not sensitive to endoglucosaminidase H, but was susceptible to the action of sialidase reflecting carbohydrate side-chains of the complex type. Pulse-chase experiments revealed a precursor-product relationship for the high-mannose and the complex type alpha 1 acute-phase globulin. In the hepatocyte medium newly synthesized alpha 1 acute-phase globulin was detected 30 min after the pulse. Unglycosylated alpha 1 acute-phase globulin was found in the cells as well as in the medium when the transfer of oligosaccharide chains onto the polypeptide chains was blocked by tunicamycin. Tunicamycin led to a marked delay in alpha 1 acute-phase globulin secretion. PMID:2578391

    Use of gestation stalls in pork production remains a controversial topic in animal welfare. Immune status and measures are frequently used to assess stress levels and thus well-being of confined animals. The important welfare issue of close confinement among gestating gilts was tested by quantifying cortisol, acute phase cytokine, and acute phase protein pro-files before and after farrowing of gilts housed in 2 systems. Landrace x Yorkshire crossbred gilts housed in groups of 4 (group, n = 8) in pens (3.9 x 2.4 m with 4 individual feeding spaces, 9.36 m(2) total or 2.34 m(2)/gilt) were compared with gilts housed in standard industry stalls (stall, n = 16; 2.2 x 0.6 m, 1.32 m(2)/gilt). Floors were fully slatted, and a substrate was not provided for either system. Cortisol was determined from saliva on d 105 of gestation, 1 h after moving the gilts into farrowing stalls (d 111), and 24 h and 7 d after farrowing. Cortisol was greater (P = 0.04) for group gilts compared with stall gilts 1 h after moving them into farrowing stalls and 24 h after farrowing. Cortisol concentrations decreased (P = 0.001) over time. Leukocyte mRNA expression of IL-1, IL-1 receptor antagonist, and tumor necrosis factor-alpha was determined by quantitative, reverse transcription PCR on d 35, 63, and 91 of gestation and 72 h after farrowing. Cytokine mRNA expression of peripheral blood mononuclear cells did not differ between housing systems for IL-1, its receptor antagonist, or for tumor necrosis factor-alpha. Acute phase proteins, including fibrinogen, haptoglobin, and alpha(1)-acid glycoprotein were determined for plasma samples taken at d 35, 63, and 91 of gestation and 72 h and 14 d after farrowing. In contrast to cortisol, plasma fibrinogen concentrations increased (P < 0.005) over time. Haptoglobin did not differ between treatments (P > 0.10). Stall gilts tended to have greater (P = 0.07) plasma alpha(1)-acid glycoprotein concentrations than group animals at d 35 of gestation and d 14

    The present work aimed to study the behavior of acute phase proteins (haptoglobin, serum amyloid A, acid soluble glycoprotein, fibrinogen, and albumin) in fasting-induced pregnancy toxemia in goats and their relationship with classical indicators of this disorder such as beta-hydroxybutyrate and nonesterified fatty acids in the blood and decreased urine pH and ketonuria. Twelve adult Murciano-Granadina goats at the final stage of gestation were used in this experiment. Pregnancy toxemia was induced in 6 goats by fasting for 72 hr. The other 6 animals were used as control group. Ketonuria was present in 4 out of 5 fasting animals at 24 hr and in all fasting animals at 48 hr of fasting. Serum nonesterified fatty acids were significantly increased at 24, 48, and 72 hr of fasting. Beta-hydroxybutyrate and haptoglobin achieved significantly increased concentrations at 48 hr and 72 hr, respectively, remaining increased during the entire study. Serum amyloid A, acid soluble glycoprotein, fibrinogen, and albumin were not affected by fasting. In conclusion, acute phase proteins (including haptoglobin) seemed not to have an advantage over traditional markers in diagnosis of fasting-induced pregnancy toxemia in goats. PMID:21217028

    The levels of two murine acute phase proteins, serum amyloid P component (SAP) and haptoglobin, have been measured in the serum of C57BL/10 female mice during syngeneic and allogeneic pregnancy. Both syngeneic and allogeneic pregnancy resulted in alterations in the levels of these proteins as compared to those observed in virgin females. Syngeneic mating resulted in an increase in concentration of both proteins during the final 3 days of pregnancy. During allogeneic pregnancy, SAP levels, after a transient increase on day 4, rose from days 6-8 and, after remaining relatively stable, increased from day 12 to reach maximum levels on day 18 of pregnancy. Levels fell dramatically during the immediate post-partum period. In contrast, although levels of haptoglobin also increased from days 6-8, for the remainder of pregnancy these increased levels remained stable. The implications of these findings are discussed in relation to the mechanisms of regulation of acute phase reactants and the immunological relationship between the mother and fetus. PMID:6409477

    The acute phase of chronic periodontitis may occur even in patients during supportive periodontal therapy. However, the details are not fully understood. Since the natural environment, including meteorology affects human health, we hypothesized that weather conditions may affect occurrence of acute phase of chronic periodontitis. The aim of this study was to investigate the relationship between weather conditions and acute phase of chronic periodontitis in patients under supportive periodontal therapy. Patients who were diagnosed with acute phase of chronic periodontitis under supportive periodontal therapy during 2011–2013 were selected for this study. We performed oral examinations and collected questionnaires and meteorological data. Of 369 patients who experienced acute phase of chronic periodontitis, 153 had acute phase of chronic periodontitis without direct-triggered episodes. When using the autoregressive integrated moving average model of time-series analysis, the independent covariant of maximum hourly range of barometric pressure, maximum hourly range of temperature, and maximum daily wind speed were significantly associated with occurrence of acute phase of chronic periodontitis (p < 0.05), and 3.1% of the variations in these occurrence over the study period were explained by these factors. Meteorological variables may predict occurrence of acute phase of chronic periodontitis. PMID:26251916

  17. Procalcitonin beyond the acute phase: novel biomediator properties?

    PubMed

    Since inflammation has been linked to carcinogenic events, discovery of relevant biomarkers may have important preventative implications. Procalcitonin (ProCT) has been shown to be an important prognostic biomarker in severe inflammatory conditions, but there is no data regarding its biomarker role, if any, beyond the acute phase. In a recent study published in BMC Medicine, Cotoi et al. analyzed whether serum ProCT levels in healthy individuals are associated with mortality outcomes. The results are affirmative in that baseline ProCT was shown to be strongly and independently associated with all-cause and cancer mortality and with the incidence of colon cancer in men. By contrast, the study indicated that high sensitivity C-reactive protein was independently associated with cardiovascular mortality but not with cancer mortality in men. Thus, baseline levels of ProCT appear to have prognostic biomarker implications potentially related to its emerging biomediator action(s). PMID:23984981

    Feed deprivation in poultry farming imposes some degree of stress to the birds, and adversely affects their well -being. Serum levels of acute phase proteins (APP) are potential physiological indicators of stress attributed to feed deprivation. However, it has not been determined how long it takes for a measurable APP response to stressors to occur in avian species. An experiment was designed to delineate the APP and circulating levels of corticosterone responses in commercial broiler chickens to feed deprivation for 30 h. It was hypothesized that feed deprivation would elicit both APP and corticosterone (CORT) reactions within 30 h that is probably associated with stress of hunger. Twenty-one day old birds were subjected to one of 5 feed deprivation periods: 0 (ad libitum, AL), 6, 12, 18, 24, and 30 h. Upon completion of the deprivation period, blood samples were collected to determine serum CORT, ovotransferrin (OVT), α1-acid glycoprotein (AGP), and ceruloplasmin (CP) concentrations. Results showed that feed deprivation for 24 h or more caused a marked elevation in CORT (P=0.002 and P<0.0001, respectively) when compared to AL. However, increases in AGP (P=0.0005), CP (P=0.0002), and OVT (P=0.0003) were only noted following 30 h of feed deprivation. It is concluded that elicitation of AGP, CP, and OVT response may represent a more chronic stressful condition than CORT response in assessing the well-being of broiler chickens.

    Procalcitonin is a protein which is found in elevated concentrations in the blood circulation during systemic bacterial, fungal or protozoal infection. In contrast to classical acute-phase proteins like C-reactive protein or interleukin-6, it is not elevated after operative trauma. In this paper we present current opinions on the assumed induction mechanisms of the protein by cytokines and endotoxin. Furthermore, the clinical value for early detection of systemic infections in abdominal and transplantation surgery is demonstrated by examples from the literature. Our investigation shows that eight patients with necrotizing pancreatitis had a PCT mean value of 6.9 ng/ml on the day of admission. Seven patients with edematous pancreatitis had only a PCT mean value of 0.69 ng/ml. Despite these differences in the mean values, a significant difference between the normal value and the mean value of the group with necrotizing pancreatitis or edematous pancreatitis was not observed due to the wide range of PCT levels in the group of patients with necrotizing pancreatitis. The fact that only a few of the patients had a superinfected necrosis with systemic evasion of bacterias or their toxins may be the reason for this wide range. We suggest that a discrimination between superinfected necrotizing or sterile pancreatitis and edematous pancreatitis by PCT could be possible but more extensive studies with microbiological examination of the necrotic material are required to recognize the subgroups and to establish the real diagnostic efficiency of PCT in clinical practice, especially in the prediction of the outcome of acute pancreatitis.

    Studies performed at space flights and earth-based simulation models detected the plasma indices of acute phase reaction (APR), i.e. the increase of APR cytokine mediators and alterations in the production of blood acute phase proteins (APP) at the initial stages of adaptation to altered gravity conditions. Acute phase response is the principal constituent of the functional activity of innate immunity system. Changes in plasma APPs contents are considered to serve the restoration of homeostasis state. According to trends of their concentration shifts at the evolving of acute phase reaction APPs are denoted as positive, neutral, or negative. Plasma concentrations of positive acute phase proteins α1-acid glycoprotein (α1-AGP), α1-antitrypsin (α1-AT), and neutral α2-macroglobulin (α2-M) were measured in human study at 12-hour antiorthostatic position (AOP) with 15° head down tilt and hypoxia experiments at 14% oxygen in pressure chamber. Both of these impacts were shown to produce alterations in the APP levels indicative for acute phase response. Nevertheless, in AOP experiment noticeable decrease in α1-AGP concentration occurred by hour 12, and even more pronounced decline of α1-AGP and α1-AT were found on hypoxia hours 12 and 36. Acute phase proteins α1-AGP and α2-M possess the features of proteinase inhibitors. This function is implemented by the formation of complexes with the molecules of proteolytic enzymes which subsequently are removed from the blood flow. Transient decrease in plasma concentrations of protease inhibitors on early phases of APR development was reported to result from the growth of plasma protease activity due to cathepsin release from activated leukocytes, which had not yet been compensated by enhanced APP synthesis. Being a carrier protein for positively charged and neutral substances, α1-AGP shows pronounced elevation in its blood content during APR development. As assumed, it is required for the transportation of the increased

    To investigate the in vivo acute phase molecular response of the brain to ionizing radiation, C3Hf/Sed/Kam mice were given midbrain or whole-body irradiation. Cerebral expression of interleukins (IL-1{alpha}, IL-1{beta}, IL-2, IL-3, IL-4, IL-5, IL-6), interferon (IFN-{gamma}), tumor necrosis factors (TNF-{alpha} and TNF-{beta}), intercellular adhesion molecule-1 (ICAM-1), inducible nitric oxide synthetase (iNOS), von Willebrand factor (vWF), {alpha}1-antichymotrypsin (EB22/5.3), and glial fibrillary acidic protein (GFAP) was measured at various times after various radiation doses by ribonuclease (RNase) protection assay. The effects of dexamethasone or pentoxifylline treatment of mice on radiation-induced gene expression were also examined. Levels of TNF-{alpha}, IL-1{beta}, ICAM-1, EB22/5.3, and to a lesser extent IL-1{alpha} and GFAP, messenger RNA were increased in the brain after irradiation, whether the dose was delivered to the whole body or only to the midbrain. Responses were radiation dose dependent, but were not found below 7 Gy; the exception being ICAM-1, which was increased by doses as low as 2 Gy. Most responses were rapid, peaking within 4-8 h, but antichymotrypsin and GFAP responses were delayed and still elevated at 24 h, by which time the others had subsided. Pretreatment of mice with dexamethasone or pentoxifylline suppressed radiation-induced gene expression, either partially or completely. Dexamethasone was more inhibitory than pentoxifylline at the doses chosen. The initial response of the brain to irradiation involves expression of inflammatory gene products, which are probably responsible for clinically observed early symptoms of brain radiotherapy. This mechanism explains the beneficial effects of the clinical use of steroids in such circumstances. 64 refs., 4 figs.

    The periparturient period is one of the most critical periods in the productive life of a dairy cow, and is the period when dairy cows are most susceptible to developing new intramammary infections (IMI) leading to mastitis. Acute phase proteins (APP) such as haptoglobin (Hp), mammary associated serum amyloid A3 (M-SAA3) and C-reactive protein (CRP) have been detected in milk during mastitis but their presence in colostrum and milk in the immediate postpartum period has had limited investigation. The hypothesis was tested that APP are a constituent of colostrum and milk during this period. Enzyme linked immunosorbent assays (ELISAs) were used to determine each APP's concentration in colostrum and milk collected daily from the first to tenth day following calving in 22 Holstein-Friesian dairy cows. Haptoglobin was assessed in individual quarters and composite milk samples while M-SAA3 and CRP concentration were determined in composite milk samples. Change in Hp in relation to the high abundance proteins during the transition from colostrum to milk were evaluated by 1 and 2 dimension electrophoresis and western blot. In 80% of the cows all APPs were detected in colostrum on the first day following parturition at moderately high levels but gradually decreased to minimal values in the milk by the 6th day after calving. The remaining cows (20%) showed different patterns in the daily milk APP concentrations and when an elevated level is detected could reflect the presence of IMI. Demonstration that APP are present in colostrum and milk following parturition but fall to low levels within 4 days means that elevated APP after this time could be biomarkers of post parturient mastitis allowing early intervention to reduce disease on dairy farms.

    In the acute phase of cerebral infarction, many experimental data suggest that free radicals including superoxide, hydroxy radical and nitric oxide are one of the most important factors to cause brain damage. We have clearly detected nitrotyrosine (a marker of endogenous production of peroxynitrite, which is readily produced from superoxide and nitric oxide) in neurons and intraparenchymal vascular walls during post-ischemic reperfusion. Free radical scavengers thus seem to be very promising tools of treatment, and one of them (edaravone) has recently been approved for clinical use in Japan. CREB (cyclic AMP response element binding protein) is a DNA-binding transcription factor, and its function is activated by phosphorylation of Ser133 residue. CREB plays important roles in neuronal development, synaptic plasticity and regeneration. We have found that phosphorylation of CREB is significantly and persistently increased in surviving neurons and oligodendrocytes in post-ischemic brain, while this phosphorylation is only transiently increased in neurons and oligodendrocytes which eventually die. These data suggest that CREB phosphorylation plays an important role in protection of ischemic brain tissue. Oligodendrocyte progenitor cells (OPC) remain abundant throughout the adult brain, and retain their ability to become not only mature oligodendrocytes, but also neurons. We have recently found that OPC are significantly activated and proliferate in the peri-infarct area at 1-2 weeks after ischemia, suggesting that OPC may be involved in the repair mechanisms of ischemic brain. Future targets of stroke treatment should include enhancement of intrinsic protection mechanisms such as CREB phosphorylation and activation of progenitors cells. PMID:12235793

    Pediatric depression entails a higher risk for psychiatric disorders, somatic complaints, suicide, and functional impairment later in life. Cognitive behavior therapy (CBT) is recommended for the treatment of depression in children, yet research is based primarily on adolescents. The present meta-analysis investigated the efficacy of CBT in children aged 8-12 years with regard to depressive symptoms. We included randomized controlled trials of CBT with participants who had an average age of  ≤ 12 years and were diagnosed with either depression or reported elevated depressive symptoms. The search resulted in 10 randomized controlled trials with 267 participants in intervention and 256 in comparison groups. The mean age of participants was 10.5 years. The weighted between-group effect size for CBT was moderate, Cohen's d = 0.66. CBT outperformed both attention placebo and wait-list, although there was a significant heterogeneity among studies with regard to effect sizes. The weighted within-group effect size for CBT was large, d = 1.02. Earlier publication year, older participants, and more treatment sessions were associated with a larger effect size. In conclusion, the efficacy of CBT in the treatment of pediatric depression symptoms was supported. Differences in efficacy, methodological shortcomings, and lack of follow-up data limit the present study and indicate areas in need of improvement.

    A brief preparatory programme, based on the principles of motivational interviewing (MI), was developed as a way of engaging clients with traumatic brain injury (TBI) and preparing them for a cognitive behaviour therapy (CBT) programme for anxiety. The MI + CBT programme was delivered to a male client in his early 40s with severe TBI at four months post-injury, using a single-subject design with repeated measures pre- and post-treatment. The client received three sessions of manualised MI, followed by nine sessions of CBT. The MI sessions focused on helping the client to develop more realistic goals and supporting his self-efficacy about his ability to cope with anxiety. Specific strategies were used to accommodate the client's cognitive limitations, such as the use of personally meaningful metaphors and role plays. Re-assessments were conducted at the end of MI, CBT and nine weeks post-treatment, using a semi-structured clinical interview and self-report measures of anxiety, mood and change expectancy. The client showed significant improvement in anxiety following treatment and a significant reduction in subjective units of distress (SUDS) between the MI and CBT phases. The results suggest the potential utility of MI in people with TBI, and the need to evaluate treatment protocols in a controlled trial.

    Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease with exacerbations involving recurrent or bilateral optic neuritis and longitudinally extensive transverse myelitis. Pulse steroid therapy is recommended as the initial, acute-phase treatment for NMO. If ineffective, treatment with plasma exchange (PE) should commence. However, no evidence exists to support the effectiveness of PE long after the acute phase. Immunoadsorption therapy (IA) eliminates pathogenic antibodies while sparing other plasma proteins. With IA, side effects of PE resulting from protein substitution can be avoided. However, whether IA is effective for NMO remains unclear. We describe a patient with anti-aquaporin-4-positive myelitis who responded to IA using a tryptophan polyvinyl alcohol gel column that was begun 52 days after disease onset following the acute phase. Even long after the acute phase when symptoms appear to be stable, IA may be effective and should not be excluded as a treatment choice.

    Would-be learners of cognitive-behavioral therapy (CBT) may be hampered by learning traps that impede effective acquisition of the skills necessary to provide this type of therapy to clients. Among these pitfalls are the possibility of isolation, therapeutic fanaticism, lack of seriousness, therapeutic drift, and thinking CBT is antipsychodynamic or antipsychoanalytic. The author advocates immersion learning of CBT, arguing that theoretical learning must be supplemented by supervision and active use of the method in one's patients. Presented are two case vignettes demonstrating therapeutic drift and therapeutic fanaticism to highlight potential therapeutic impasses that may ensue from these pitfalls. PMID:18251384

    Acute phase response is an effector process orchestrated by the innate immune system for the optimal mobilization of the resources of the organism distant from the local insult site needed in the execution of a host-protecting reaction. Our research has shown that mice bearing tumors treated by photodynamic therapy (PDT) exhibit the three major hallmarks of acute phase response: release of acute phase reactants, neutrophilia, and pituitary/adrenal axis activation. Of particular interest in this study were acute phase proteins that have a pivotal role in the clearance of dead cells, since the occurrence of this process in PDT-treated tumors emerges as a critical event in the course of PDT-associated host response. It is shown that this type of acute phase reactants, including complement proteins (C3, C5, C9, mannose-binding lectin, and ficolin A) and related pentraxins (serum amyloid P component and PTX3), are upregulated following tumor PDT and accumulate in the targeted lesions. Based on the recently accumulated experimental evidence it is definitely established that the acute phase response is manifested in the hosts bearing PDT-treated tumors and it is becoming clear that this effector process is an important element of PDT-associated host response bearing in impact on the eventual outcome of this therapy.

  17. Cognitive behavioural therapy (CBT) for anxiety in people with dementia: study protocol for a randomised controlled trial

    2012-01-01

    Background Many people with dementia experience anxiety, which can lead to decreased independence, relationship difficulties and increased admittance to care homes. Anxiety is often treated with antipsychotic medication, which has limited efficacy and serious side effects. Cognitive behavioural therapy (CBT) is widely used to treat anxiety in a range of populations, yet no RCTs on CBT for anxiety in dementia exist. This study aims to develop a CBT for anxiety in dementia manual and to determine its feasibility in a pilot RCT. Methods/design Phase I involves the development of a CBT for anxiety in dementia manual, through a process of (1) focus groups, (2) comprehensive literature reviews, (3) expert consultation, (4) a consensus conference and (5) field testing. Phase II involves the evaluation of the manual with 50 participants with mild to moderate dementia and anxiety (and their carers) in a pilot, two-armed RCT. Participants will receive either ten sessions of CBT or treatment as usual. Primary outcome measures are anxiety and costs. Secondary outcome measures are participant quality of life, behavioural disturbance, cognition, depression, mood and perceived relationship with the carer, and carer mood and perceived relationship with the person with dementia. Measures will be administered at baseline, 15 weeks and 6 months. Approximately 12 qualitative interviews will be used to gather service-users' perspectives on the intervention. Discussion This study aims to determine the feasibility of CBT for people with anxiety and dementia and provide data on the effect size of the intervention in order to conduct a power analysis for a definitive RCT. The manual will be revised according to qualitative and quantitative findings. Its publication will enable its availability throughout the NHS and beyond.

    Background The infectivity of the HIV-1 acute phase has been directly measured only once, from a retrospectively identified cohort of serodiscordant heterosexual couples in Rakai, Uganda. Analyses of this cohort underlie the widespread view that the acute phase is highly infectious, even more so than would be predicted from its elevated viral load, and that transmission occurring shortly after infection may therefore compromise interventions that rely on diagnosis and treatment, such as antiretroviral treatment as prevention (TasP). Here, we re-estimate the duration and relative infectivity of the acute phase, while accounting for several possible sources of bias in published estimates, including the retrospective cohort exclusion criteria and unmeasured heterogeneity in risk. Methods and Findings We estimated acute phase infectivity using two approaches. First, we combined viral load trajectories and viral load-infectivity relationships to estimate infectivity trajectories over the course of infection, under the assumption that elevated acute phase infectivity is caused by elevated viral load alone. Second, we estimated the relative hazard of transmission during the acute phase versus the chronic phase (RHacute) and the acute phase duration (dacute) by fitting a couples transmission model to the Rakai retrospective cohort using approximate Bayesian computation. Our model fit the data well and accounted for characteristics overlooked by previous analyses, including individual heterogeneity in infectiousness and susceptibility and the retrospective cohort's exclusion of couples that were recorded as serodiscordant only once before being censored by loss to follow-up, couple dissolution, or study termination. Finally, we replicated two highly cited analyses of the Rakai data on simulated data to identify biases underlying the discrepancies between previous estimates and our own. From the Rakai data, we estimated RHacute = 5.3 (95% credibility interval [95% CrI]: 0

    The Partnerships for Families project is a randomized clinical trial designed to evaluate the implementation of Alternatives for Families: A Cognitive-Behavioral Therapy (AF-CBT), an evidence-based treatment for family conflict, coercion, and aggression, including child physical abuse. To evaluate the effectiveness of a training program in this model, 182 community practitioners from 10 agencies were randomized to receive AF-CBT training (n = 90) using a learning community model (workshops, consultation visits) or Training as Usual (TAU; n = 92) which provided trainings per agency routine. Practitioners completed self-report measures at four time points (0, 6, 12, and 18 months following baseline). Of those assigned to AF-CBT, 89% participated in at least one training activity and 68% met a "training completion" definition. A total of 80 (44%) practitioners were still active clinicians in the study by 18-month assessment in that they had not met our staff turnover or study withdrawal criteria. Using an intent-to-train design, hierarchical linear modeling analyses revealed significantly greater initial improvements for those in the AF-CBT training condition (vs. TAU condition) in CBT-related knowledge and use of AF-CBT teaching processes, abuse-specific skills, and general psychological skills. In addition, practitioners in both groups reported significantly more negative perceptions of organizational climate through the intervention phase. These significant, albeit modest, findings are discussed in the context of treatment training, research, and work force issues as they relate to the diverse backgrounds, settings, and populations served by community practitioners.

  2. The pathophysiology of the acute phase of human bartonellosis resembles AIDS.

    Human bartonellosis is a South American anthroponosis caused by Bartonella bacilliformis. The disease has an acute phase characterized by invasion of red blood cells by parasites, and consequent severe anemia; and a chronic phase presenting with benign vascular tumors. During the acute phase, affected individuals are prone to developing opportunistic infections with a variety of organisms similar to the ones seen in AIDS. After antibiotic treatment is instituted, a subgroup of patients may develop atypical symptoms which potentially represent clinical manifestations of the restoration of macrophage function. We speculate that the pathophysiology of the acute phase of human bartonellosis resembles AIDS, with a period of immunosuppression following the infection and later, clinical manifestations of immune reconstitution subsequent to treatment.

    Ethionine administered intraperitoneally to rats suffering from turpentine-induced inflammation preferentially reduced incorporation of 14C-leucine into fibrinogen, haptoglobin and other acute-phase proteins. The inhibitory effect was observed both in vivo and in liver slices obtained from ethionine-treated donors, while addition of ethionine to liver slices in vitro led to general reduction of synthesis of all liver and plasma proteins, including albumin. For comparison, the effects of galactosamine and actinomycin D on plasma protein synthesis in injured rats were also examined. It has been concluded that ethionine acts in the early phases of the acute-phase response, probably by inhibition of trauma-induced transcription of liver mRNA specific for acute-phase proteins.

    The true pathophysiologic nature of Peyronie's disease continues to evolve. This pathology often results in a penile plaque(s), penile deformity, curvature, pain, and erectile dysfunction. Clinically, there are two distinct phases, acute and chronic. The focus of this review will center on the management of the acute phase of Peyronie's disease. While little data exists demonstrating disease resolution, disease stabilization is an important clinical goal for patients as this often allows acceptable sexual function. Thus, medical management during the acute phase of Peyronie's disease is aimed at limiting and stabilizing the degree of penile fibrosis, decreasing penile curvature, and reducing penile pain. In this manuscript we explain different therapies; oral, topical, intralesional injection and others like extracorporeal shockwave (ESWT), radiation and penile traction for acute phase of Peyronie's disease. Although no consensus exists for the treatment of acute phase Peyronie's disease, a majority of patients can achieve stabilization and in some cases regression of their disease with proper medical therapy. The goals of therapy should be discussed extensively with each patient, noting that erectile function will be likely despite some degree of curvature.

    Acute phase changes in trace mineral metabolism were examined in turkey embryos. An endotoxin injection resulted in increased concentrations of serum copper and liver zinc and decreased concentrations of serum zinc in embryos incubated either in ovo or ex ovo. Changes in zinc and copper metabolism occurred when endotoxin either was injected intramuscularly, into the amnionic fluid, or administered onto the chorioallantoic membrane. Unlike poults, embryos did not respond to an inflammatory challenge with decreased serum iron concentrations. Acute phase changes in embryo serum zinc and copper as well as liver zinc concentrations were similar to those in poults. Increased liver zinc concentrations were associated with increased zinc in metallothionein (MT). An injection of a crude interleukin 1 preparation into embryos resulted in similar increases in hepatic zinc and MT concentrations as an endotoxin injection, suggesting a role for this cytokine in mediating the acute phase changes in embryonic zinc metabolism.

  7. CBT for Adolescents With Anxiety: Mature Yet Still Developing.

    2015-06-01

    Anxiety disorders are common in adolescents (ages 12 to 18) and contribute to a range of impairments. There has been speculation that adolescents with anxiety are at risk for being treatment nonresponders. In this review, the authors examine the efficacy of cognitive-behavioral therapy (CBT) for adolescents with anxiety. Outcomes from mixed child and adolescent samples and from adolescent-only samples indicate that approximately two-thirds of youths respond favorably to CBT. CBT produces moderate to large effects and shows superiority over control/comparison conditions. The literature does not support differential outcomes by age: adolescents do not consistently manifest poorer outcomes relative to children. Although extinction paradigms find prolonged fear extinction in adolescent samples, basic research does not fully align with the processes and goals of real-life exposure. Furthermore, CBT is flexible and allows for tailored application in adolescents, and it may be delivered in alternative formats (i.e., brief, computer/Internet, school-based, and transdiagnostic CBT).

After approval by the ethics committee of our hospital, we investigated the plasma concentrations of IL-2, -6, -8, -10, and -13, the soluble IL-2 receptor (sIL-2R), and the acute phase proteins procalcitonin (PCT) and C-reactive protein (CRP) at admission and every 3 days in 24 patients over a time course of 28 days after thermal injury and categorized by percent burn: < or =30% (group 1; n=12) and >30% (group 2; n=12). Shortly after burn injury we found higher concentrations of IL-2, -6, -10 and PCT in those patients >30% TBSA. During the study period, we found significant higher levels of acute phase proteins, IL-6 and -8 in patients >30% TBSA. The incidence of SIRS and MODS was three times increased in patients >30% TBSA. Our results show different patterns of cytokines and acute phase proteins in patients with different burned surface areas over a long time and continuous monitoring of a more distinct inflammatory response in these patients.

    Systemic inflammatory reactions are a prominent feature of many parasitic infections and the cellular and humoral components of the acute phase reaction may have an impact on the host-parasite relationship. We examined serum changes of four acute phase reactants: alpha 1-proteinase inhibition (alpha 1Pi); complement C3; serum amyloid A protein (SAA); and serum amyloid P component (SAP), in mice undergoing a primary infection with Nippostrongylus brasiliensis. SAA and SAP showed changes within the first 2 days of infection indicating the presence of an acute phase response associated with inflammation in the lung. Alpha 1Pi and C3 serum levels were not altered. However, all four acute phase reactants were synthesized in greater amounts by primary cultures of hepatocytes taken from infected animals at this time. Subsequently, as parasite-mediated inflammatory changes occur in the gut, both serum and hepatocyte cultures demonstrate an acute inflammatory response in all four reactants. It is proposed that the early reaction between parasites and macrophage/monocyte lead to the release of a mediator of inflammation which initiates the hepatocyte response. In this infection, at least one of the APR is shown to localize to the site of inflammation influencing the host-parasite relationship. Images Figure 2 Figure 3 PMID:6204934

    The objective of this study was to determine the effects of investigational vaccine candidates on acute-phase proteins (APPs) as determined in GLP toxicology studies. Sixty-four GLP toxicity studies, which were submitted to the Food and Drug Administration from 2008 to 2012 in support of proposed clinical investigations, were reviewed and entered into a database. These studies employed the intramuscular route of injection and were conducted using New Zealand White rabbits. A retrospective review of these GLP toxicity studies was conducted to evaluate the changes in plasma levels of C-reactive protein (CRP), fibrinogen, and albumin as APPs following the administration of various investigational vaccines. The incidence and intensity of responses associated with acute-phase responses both positive and negative were observed to increase in animals when treated with vaccines containing more potent immunological components such as novel adjuvants that activate Toll-like receptors in the investigational vaccine products. Changes in plasma levels of CRP were prominent among these responses and provided a basis to propose a classification scheme of H, M, L, and N responding groups. These changes in plasma proteins reflect an activation of the acute-phase response and indicate increasing levels of systemic inflammation, which potentially may be correlated with important clinical adverse events.

    While progress has been made in improving survival following myocardial infarction, this injury remains a major source of mortality and morbidity despite modern reperfusion therapy. While one approach has been to develop therapies to reduce lethal myocardial cell reperfusion injury, this concept has not translated to the clinics, and several recent negative clinical trials raise the question of whether reperfusion injury is important in humans undergoing reperfusion for acute ST segment elevation myocardial infarction. Therapy aimed at reducing myocardial cell death while the myocytes are still ischemic is more likely to further reduce myocardial infarct size. Developing new therapies to further reduce left ventricular remodeling after the acute event is another approach to preserving structure and function of the heart after infarction. Such therapy may include chronic administration of pharmacologic agents and/or therapies developed from the field of regenerative cardiology, including cellular or non-cellular materials such as extracellular matrix. The optimal therapy will be to administer agents that both reduce myocardial infarct size in the acute phase of infarction as well as reduce adverse left ventricular remodeling during the chronic or healing phase of myocardial infarction. Such a dual approach will help optimize the preservation of both cardiac structure and function.

    The adrenal cortex has a molecular clock that generates circadian rhythms in glucocorticoid production, yet it is unclear how the clock responds to acute stress. We hypothesized that stress-induced ACTH provides a signal that phase shifts the adrenal clock. To assess whether acute stress phase shifts the adrenal clock in vivo in a phase-dependent manner, mPER2:LUC mice on a 12:12-h light:dark cycle underwent restraint stress for 15 min or no stress at zeitgeber time (ZT) 2 (early subjective day) or at ZT16 (early subjective night). Adrenal explants from mice stressed at ZT2 showed mPER2:LUC rhythms that were phase-advanced by ~2 h, whereas adrenals from mice stressed at ZT16 showed rhythms that were phase-delayed by ~2 h. The biphasic response was also observed in mice injected subcutaneously either with saline or with ACTH at ZT2 or ZT16. Blockade of the ACTH response with the glucocorticoid, dexamethasone, prevented restraint stress-induced phase shifts in the mPER2:LUC rhythm both at ZT2 and at ZT16. The finding that acute stress results in a phase-dependent shift in the adrenal mPER2:LUC rhythm that can be blocked by dexamethasone indicates that stress-induced effectors, including ACTH, act to phase shift the adrenal clock rhythm.

    The current study is a secondary analysis of data from a randomized controlled trial of CBT for late-life GAD (Stanley et al., 2014) which provided an opportunity to examine predictors of outcome among those who received CBT. Participants were 150 older adults who were randomized to receive 10 sessions of CBT. Completer analyses found that homework completion, number of sessions attended, lower worry severity, lower depression severity, and recruitment site predicted 6-month worry outcome on the PSWQ-A, whereas homework completion, credibility of the therapy, lower anxiety severity, and site predicted 6-month anxiety outcome on the STAI-T. In intent-to-treat multivariate analyses, however, only initial worry and anxiety severity, site, and number of sessions completed predicted treatment outcome. These results are largely consistent with predictors of outcome in younger adults and suggest that lower initial symptom severity and variables consistent with greater engagement in treatment predict outcome.

    Many clients in publicly funded substance abuse treatment programs suffer from depression yet lack access to effective mental health treatment. This study sought to examine whether addiction counselors could be effectively trained to deliver group CBT for depression and to ascertain client perceptions of the treatment. Five counselors were trained in the therapy and treated 113 clients with depression symptoms. Counselors demonstrated high fidelity to the therapy and client perceptions of the therapy were positive. Our results suggest that training addiction counselors to deliver group CBT for depression is a promising integrated treatment approach for co-occurring depression and substance disorders.

    The intestinal immune dysfunction due to loss of mucosal and peripheral CD4(+) T cells in individuals with HIV/AIDS is presumably responsible for the establishment of persistent cryptosporidiosis. Simian immunodeficiency virus (SIV)-infected macaques were used to investigate the phase/timing in SIV infection, which permits a self-limiting Cryptosporidium parvum infection to become persistent in immunodeficient hosts because of significant mucosal immune defects. Two groups of SIV-infected macaques were challenged with C. parvum; one was challenged during the acute SIV infection phase (2 weeks post-SIV infection) and the second was challenged during the chronic SIV phase (CD4 counts 200-500 cells/μl of blood). Samples (fecal, blood, biopsy, and necropsy) were collected at different time points after infection to correlate the progression of disease with the immune status of the animals. All seven SIV-infected macaques challenged during the acute phase of SIV infection became persistently infected and excreted oocysts for 1-4 months. However, four of the six in the chronic SIV phase became infected with cryptosporidiosis, of which one survived 2 weeks and one became naturally infected. Sequential analysis of CD4(+) in blood and intestines of coinfected macaques exhibited pronounced losses of CD4 T cells during the first 2 weeks after SIV infection, followed by transient rebound of CD4 T cells in the gut after C. parvum infection, and then a gradual loss over subsequent months. Persistent cryptosporidiosis was more consistently induced during the acute SIV phase indicating that profound viral damage to gut lymphoid tissue during the acute phase was more conducive, compared with the chronic phase, to establishing persistent cryptosporidiosis than low circulating CD4 T cells.

    The C-reactive protein (CRP), first described as a serum component capable of precipitating the C-polysaccharide of pneumococci, is one of the most important proteins because the serum concentration rises in the acute phase reaction. The acute phase reaction is the nonspecific reaction of the body to noxious stimuli of the most varied kinds, such as infections, burns, neoplasms and tissue trauma. The CRP is synthesized in liver parenchymal cells by cytokines which are derived from stimulated leucocytes and released into the circulation. Because of its molecular structure and in synergy with the complement system, it is able to precipitate and/or lyse microorganisms, thereby rendering them harmless. Measurement of the serum CRP concentration can provide important information with respect to the diagnosis and monitoring of treatment. Due to immunosenescence in geriatric patients the synthesis of CRP appears to be limited to inflammatory stimuli; however, this phenomenon does not appear to be of major clinical relevance. Despite the introduction of new parameters of the acute phase reaction, sometimes with better performance, such as interleukin-6, procalcitonin and the soluble endotoxin receptor sCD14, measurement of CRP for diagnosis and treatment monitoring is still justified even in geriatric patients as testing is rapid, economic and nearly ubiquitously available round the clock. Biochemical markers of the acute phase reaction should always be interpreted together with the clinical picture and their specific limitations.

    The goal of this study was to assess the diagnostic accuracy of acute phase proteins and proinflammatory cytokines in sheep with pneumonic pasteurellosis. Blood samples were collected from 56 sheep (36 naturally infected with Pasteurella multocida and 20 healthy controls) belonging to one farm in Eastern region, Saudi Arabia. Serum samples were evaluated for acute phase proteins (Haptoglobin (Hp), serum amyloid A (SAA) and fibrinogen (Fb)), and the proinflammatory cytokines (interleukins (IL-1α, IL-1β, and IL-6), tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-ϒ)). Additionally, nasopharyngeal swabs and bronchoalveolar lavages were collected from all animals for bacteriological examinations. Receiver operating characteristic curve was used to assess the diagnostic performance of each parameter. All parameters showed moderate to high degree of positive correlation with case-control status. There was no significant difference in the area under the curve (AUC) among acute phase proteins; however, both Hp and SAA showed better sensitivity and specificity than Fb. The proinflammatory cytokines (IL1-α, IL1-β, and IL6) showed similar and highly accurate diagnostic performance (AUC > 0.9), whereas IFN-ϒ was moderately accurate (AUC = 0.79). In conclusion, this study confirms the value of acute phase proteins and cytokines as diagnostic biomarkers of naturally occuring pneumonic pasteurellosis in sheep. PMID:27547520

    We investigated the potential role of interleukin-6 as a mediator of the acute-phase reaction (APR) in patients with acute myocardial infarction. Of the six patients studied, five demonstrated increased plasma interleukin-6 levels. Interleukin-6 levels began to increase at 14 hours (mean; range = 8 to 20 hours) after the initial complaints and reached maximal levels of 28 to 250 U/mL (normal values less than 10 U/mL) after 36 hours (mean; range = 24 to 52 hours). No correlation was seen between the size of the interfaction as indicated by creatine kinase MB assays and the extent of the interleukin-6 increases (r = 0.44; p = 0.38). As an indicator of the APR, plasma C-reactive protein (CRP) levels were measured. CRP levels began to increase after 16 hours (mean; range = 8 to 24 hours) and reached maximum levels of 56 to 322 mg/L (normal values less than 3 mg/L) after 65 hours (mean; range = 48 to 92 hours). The increase of the interleukin-6 level preceded the increase of the CRP level in three patients and was simultaneous in two patients. Maximal interleukin-6 levels correlated significantly with maximal CRP levels (r = 0.96; p = 0.002). Thus these findings indicate that interleukin-6 is an important endogenous mediator for the APR in patients with acute myocardial infarction.

    An adequate treatment of ischaemic stroke in the early phase (28-48 h) is the most important factor for a better outcome. Thrombolysis with rTPA (within 3 h) and oral ASA 300 mg/days are the first therapeutic misures. Continuous monitoring of cardiological and haemodinamic parameters allows early detection of cardiac disturbances. Treatment of hypertension, low haematic oxigenation, hyperglicaemia, seizures and hypertermia is basic to improve outcome. Pharmacological therapy is only one of the components of effective multidisciplinary integrated management of ischaemic stroke; we remind also the precocity of rehabilitation procedures and an accurate psychological assessment.

    Little is understood about the relationship between therapist competence and the outcome of patients treated for common mental health disorders. Understanding the relationship between competence and patient outcome is of fundamental importance to the dissemination and implementation of Cognitive Behavioural Therapy (CBT). The current study extends existing literature by exploring the relationship between CBT competence and patient outcome in routine clinical practice within the framework of the British Government's Improving Access to Psychological Therapies (IAPT) programme. Participants comprised 43 therapists treating 1247 patients over a training period of one year. Results found little support of a general association between CBT competence and patient outcome; however significantly more patients of the most competent therapists demonstrated a reliable improvement in their symptoms of anxiety than would be expected by chance alone, and fewer experienced no reliable change. Conversely, significantly more patients treated by the least competent therapists experienced a reliable deterioration in their symptoms than would be expected. The implications of these results for the dissemination and implementation of CBT are discussed.

    Many youth experience ongoing trauma exposure, such as domestic or community violence. Clinicians often ask whether evidence-based treatments containing exposure components to reduce learned fear responses to historical trauma are appropriate for these youth. Essentially the question is, if youth are desensitized to their trauma experiences, will this in some way impair their responding to current or ongoing trauma? The paper addresses practical strategies for implementing one evidence-based treatment, Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth with ongoing traumas. Collaboration with local therapists and families participating in TF-CBT community and international programs elucidated effective strategies for applying TF-CBT with these youth. These strategies included: 1) enhancing safety early in treatment; 2) effectively engaging parents who experience personal ongoing trauma; and 3) during the trauma narrative and processing component focusing on a) increasing parental awareness and acceptance of the extent of the youths’ ongoing trauma experiences; b) addressing youths’ maladaptive cognitions about ongoing traumas; and c) helping youth differentiate between real danger and generalized trauma reminders. Case examples illustrate how to use these strategies in diverse clinical situations. Through these strategies TF-CBT clinicians can effectively improve outcomes for youth experiencing ongoing traumas. PMID:21855140

    Inhalation of ambient and workplace particulate air pollution is associated with increased risk of cardiovascular disease. One proposed mechanism for this association is that pulmonary inflammation induces a hepatic acute phase response, which increases risk of cardiovascular disease. Induction of the acute phase response is intimately linked to risk of cardiovascular disease as shown in both epidemiological and animal studies. Indeed, blood levels of acute phase proteins, such as C-reactive protein and serum amyloid A, are independent predictors of risk of cardiovascular disease in prospective epidemiological studies. In this review, we present and review emerging evidence that inhalation of particles (e.g., air diesel exhaust particles and nanoparticles) induces a pulmonary acute phase response, and propose that this induction constitutes the causal link between particle inhalation and risk of cardiovascular disease. Increased levels of acute phase mRNA and proteins in lung tissues, bronchoalveolar lavage fluid and plasma clearly indicate pulmonary acute phase response following pulmonary deposition of different kinds of particles including diesel exhaust particles, nanoparticles, and carbon nanotubes. The pulmonary acute phase response is dose-dependent and long lasting. Conversely, the hepatic acute phase response is reduced relative to lung or entirely absent. We also provide evidence that pulmonary inflammation, as measured by neutrophil influx, is a predictor of the acute phase response and that the total surface area of deposited particles correlates with the pulmonary acute phase response. We discuss the implications of these findings in relation to occupational exposure to nanoparticles.

    Background Alcohol abuse is associated with impaired circadian rhythms and sleep. Ethanol administration disrupts circadian clock phase-resetting, suggesting a mode for the disruptive effect of alcohol abuse on the circadian timing system. In this study, we extend previous work in C57BL/6J mice to: 1) characterize the SCN pharmacokinetics of acute systemic ethanol administration; 2) explore the effects of acute ethanol on photic and non-photic phase-resetting; and 2) determine if the SCN is a direct target for photic effects. Methods First, microdialysis was used to characterize the pharmacokinetics of acute i.p. injections of 3 doses of ethanol (0.5, 1.0 and 2.0 g/kg) in the mouse suprachiasmatic (SCN) circadian clock. Second, the effects of acute i.p. ethanol administration on photic phase-delays and serotonergic ([+]8-OH-DPAT-induced) phase-advances of the circadian activity rhythm were assessed. Third, the effects of reverse-microdialysis ethanol perfusion of the SCN on photic phase-resetting were characterized. Results Peak ethanol levels from the 3 doses of ethanol in the SCN occurred within 20–40 min post-injection with half-lives for clearance ranging from 0.6–1.8 hr. Systemic ethanol treatment dose-dependently attenuated photic and serotonergic phase-resetting. This treatment also did not affect basal SCN neuronal activity as assessed by Fos expression. Intra-SCN perfusion with ethanol markedly reduced photic phase-delays. Conclusions These results confirm that acute ethanol attenuates photic phase-delay shifts and serotonergic phase-advance shifts in the mouse. This dual effect could disrupt photic and non-photic entrainment mechanisms governing circadian clock timing. It is also significant that the SCN clock is a direct target for disruptive effects of ethanol on photic shifting. Such actions by ethanol could underlie the disruptive effects of alcohol abuse on behavioral, physiological, and endocrine rhythms associated with alcoholism. PMID:21463340

    Background Acute phase proteins haptoglobin (Hp), serum amyloid A (SAA) and lipopolysaccharide binding protein (LBP) have suggested to be suitable inflammatory markers for bovine mastitis. The aim of the study was to investigate acute phase markers along with clinical parameters in two consecutive intramammary challenges with Escherichia coli and to evaluate the possible carry-over effect when same animals are used in an experimental model. Methods Mastitis was induced with a dose of 1500 cfu of E. coli in one quarter of six cows and inoculation repeated in another quarter after an interval of 14 days. Concentrations of acute phase proteins haptoglobin (Hp), serum amyloid A (SAA) and lipopolysaccharide binding protein (LBP) were determined in serum and milk. Results In both challenges all cows became infected and developed clinical mastitis within 12 hours of inoculation. Clinical disease and acute phase response was generally milder in the second challenge. Concentrations of SAA in milk started to increase 12 hours after inoculation and peaked at 60 hours after the first challenge and at 44 hours after the second challenge. Concentrations of SAA in serum increased more slowly and peaked at the same times as in milk; concentrations in serum were about one third of those in milk. Hp started to increase in milk similarly and peaked at 36–44 hours. In serum, the concentration of Hp peaked at 60–68 hours and was twice as high as in milk. LBP concentrations in milk and serum started to increase after 12 hours and peaked at 36 hours, being higher in milk. The concentrations of acute phase proteins in serum and milk in the E. coli infection model were much higher than those recorded in experiments using Gram-positive pathogens, indicating the severe inflammation induced by E. coli. Conclusion Acute phase proteins would be useful parameters as mastitis indicators and to assess the severity of mastitis. If repeated experimental intramammary induction of the same animals

    Chemotherapy remains the first-choice option for adjuvant therapy in breast cancer. Here, we investigated the impact of the first chemotherapic cycle of doxorubicin on the plasmatic-proteomic profiling of women diagnosed with breast cancer (n = 87). Blood samples were obtained from the same patient before and after doxorubicin infusion (1 h, 60 mg/m(2)) and processed for label-free LC-MS proteomic screening. A total of 80 proteins were downregulated after chemotherapy. In silico analysis revealed that the main biological process enrolled was inflammation and canonical pathways involving acute phase proteins. TNF-α, IL-1β, IL-12, TGF-β1, clusterin, and gelsolin were chosen as relevant for further validation. All selected targets presented reduced plasmatic levels after treatment. Our results indicate that doxorubicin downregulated acute phase proteins immediately after its infusion. Since such proteins are cancer promoting, its downregulation could support the effectiveness of doxorubicin along treatment.

    Objective We examine remission rate probabilities, recovery rates, and residual symptoms across 36 weeks in the Treatment for Adolescents with Depression Study (TADS). Method TADS, a multisite clinical trial, randomized 439 adolescents with major depressive disorder (MDD) to 12 weeks of treatment to fluoxetine (FLX), cognitive behavioral therapy (CBT), their combination (COMB), or pill placebo (PBO). The PBO group, treated openly after week 12, was not included in the subsequent analyses. Treatment differences in remission rates and probabilities of remission over time are compared. Recovery rates in remitters at week 12 (acute phase remitters) and week 18 (continuation phase remitters) are summarized. We also examined whether residual symptoms at the end of 12 weeks of acute treatment predicted later remission. Results At Week 36, the estimated remission rates for intention-to-treat cases were: COMB: 60%, FLX: 55%; CBT: 64%; overall: 60%. Paired comparisons reveal that at week 24 all active treatments converge on remission outcomes. The recovery rate at Week 36 was 65% for acute phase remitters and 71% for continuation phase remitters, with no significant between-treatment differences in recovery rates. Residual symptoms at the end of acute treatment predicted failure to achieve remission at weeks 18 and 36. Conclusions The majority of depressed adolescents in all three treatment modalities achieved remission at the end of nine months of treatment. PMID:19127172

    Alcohol abuse is associated with sleep problems, which are often linked to circadian rhythm disturbances. However, there is no information on the direct effects of ethanol on the mammalian circadian clock. Acute ethanol inhibits glutamate signaling, which is the primary mechanism through which light resets the mammalian clock in the suprachiasmatic nucleus (SCN). Glutamate and light also inhibit circadian clock resetting induced by non-photic signals, including serotonin. Thus, we investigated the effects of acute ethanol on both glutamatergic and serotoninergic resetting of the SCN clock in vitro. We show that ethanol dose-dependently inhibits glutamate-induced phase shifts and enhances serotonergic phase shifts. The inhibition of glutamate-induced phase shifts is not affected by excess glutamate, glycine or D-serine, but is prevented by excess brain-derived neurotrophic factor (BDNF). BDNF is known to augment glutamate signaling in the SCN and to be necessary for glutamate/light-induced phase shifts. Thus, ethanol may inhibit glutamate-induced clock resetting at least in part by blocking BDNF enhancement of glutamate signaling. Ethanol enhancement of serotonergic phase shifts is mimicked by treatments that suppress glutamate signaling in the SCN, including antagonists of glutamate receptors, BDNF signaling and nitric oxide synthase. The combined effect of ethanol with these treatments is not additive, suggesting they act through a common pathway. Our data indicate further that the interaction between serotonin and glutamate in the SCN may occur downstream from nitric oxide synthase activation. Thus, acute ethanol disrupts normal circadian clock phase regulation, which could contribute to the physiological and psychological problems associated with alcohol abuse. PMID:18313227

    Kynurenines are a wide range of catabolites which derive from tryptophan through the “Kynurenine Pathway” (KP). In addition to its peripheral role, increasing evidence shows a role of the KP in the central nervous system (CNS), mediating both physiological and pathological functions. Indeed, an imbalance in this route has been associated with several neurodegenerative disorders such as Alzheimer’s and Huntington’s diseases. Altered KP catabolism has also been described during both acute and chronic phases of stroke; however the contribution of the KP to the pathophysiology of acute ischemic damage and of post-stroke disorders during the chronic phase including depression and vascular dementia, and the exact mechanisms implicated in the regulation of the KP after stroke are not well established yet. A better understanding of the regulation and activity of the KP after stroke could provide new pharmacological tools in both acute and chronic phases of stroke. In this review, we will make an overview of CNS modulation by the KP. We will detail the KP contribution in the ischemic damage, how the unbalance of the KP might trigger an alteration of the cognitive function after stroke as well as potential targets for the development of new drugs.

    Background: Treatment of acute leukemia's- a common childhood malignancy, involves intensive and powerful multi-drug chemotherapeutic regime. Oral lesions are a common complication in these patients affecting oral health status. Aim: This study was conducted to evaluate and assess the oral health status of newly diagnosed leukemic pediatric patients during induction phase and its correlation to outcome of induction therapy. Material Methods: Oral examinations was done in 33 children between the age group of 5-15 years with acute lymphoblastic leukemia (ALL) and acute myloblastic leukemia (AML), who were undergoing chemotherapy. Oral Hygiene Index- Simplified, (OHI-S) decayed missing filled teeth index (def/DMFT), Loe and Sillness index for gingiva, and complete blood count at first and fourth week of induction phase were recorded for each patient. The changes in the oral health status were analyzed with Wilcoxon signed rank test. Results: During an induction phase it was observed that level of OHI-S (P = 0.002), Loe and Sillness index (P = 0.003), def/DMFT index (P = 0.076), platelet count (P = 0.00) increased significantly and no significant difference was noted in hemoglobin (P = 0.4) and total leucocytes count (P = 0.11). Conclusion: It was observed that, although oral health status had significantly worsened, the induction outcome was not affected. PMID:25006282

    Poststroke depression (PSD) is a critical complication which might lead to unfavorable outcomes. However, most cases of PSD in the acute phase, during the 2 or 3 weeks following a stroke, are neglected because of the variable comorbid conditions. In this study, aimed at revealing the outstanding symptoms of PSD during the acute phase, consecutive patients with intracranial hemorrhage (ICH) or brain infarction (BI) were asked to fill out a depression questionnaire (Quick Inventory of Depressive Symptomatology Self-Report: QIDS-SR) at 1 week and 1 month following stroke onset. Patients with disturbed consciousness or aphasia were excluded from this study. Forty-nine ICH patients and 222 BI patients completed the QIDS-SR at 1 week and 27 of ICH and 62 of BI at 1 month. The PSD rate was 67% and 46% at 1 week in ICH and BI, respectively. Although sleep disturbance was the most frequent symptom of PSD, psychomotor agitation and appetite disturbance were the most distinguishing symptoms in ICH at 1 week and fatigue at 1 month. On the other hand, most of the depressive symptoms addressed in QIDS-SR were observed in PSD of BI patients both at 1 week and 1 month. In conclusion, while sleep disturbance was a frequent but non-specific symptom, appetite disturbance and fatigue might be critical symptoms to suggest PSD during the acute phase of stroke.

    The present study aimed to assess potential changes in acute phase proteins in sheep experimentally infected with Trypanosoma vivax. There were studied eight male sheep, four used as controls and four infected with 10(5) T. vivax trypomastigotes. Blood samples were collected at two points times before infection and then at 5,7, 9, 11, 13, 15, 20, 30, 45, 60, 75, 90, 105 and 120 days post-infection (dpi). Blood samples were centrifuged and allotted, and acute phase proteins were then separated by electrophoresis on acrylamide gel containing sodium dodecyl sulfate. Protein concentrations were determined by computer-assisted densitometry. Total protein was determined by colorimetric biuret method. Trypanosomes were counted daily using a 5 mL aliquot of blood smear on a glass slide under a 22 × 22 mm coverslip. Parasites were counted in 100 microscopic fields (40× magnification), and then multiplied by a correction factor. The results were expressed as parasites per mL of blood. For statistical analyses, we used the Wilcoxon test at 5% significance level. There was found a reduction in several acute phase proteins and increase in antitrypsin and transferrin. This finding can be used for the diagnosis of T. vivax infection, especially in chronic infection.

  10. Placental thrombosis in acute phase abortions during experimental Toxoplasma gondii infection in sheep

    PubMed Central

    2014-01-01

    After oral administration of ewes during mid gestation with 2000 freshly prepared sporulated oocysts of T. gondii isolate M4, abortions occurred between days 7 and 11 in 91.6% of pregnant and infected ewes. Afterwards, a further infection was carried out at late gestation in another group of sheep with 500 sporulated oocysts. Abortions happened again between days 9 and 11 post infection (pi) in 58.3% of the infected ewes. Classically, abortions in natural and experimental ovine toxoplasmosis usually occur one month after infection. Few experimental studies have reported the so-called acute phase abortions as early as 7 to 14 days after oral inoculation of oocysts, and pyrexia was proposed to be responsible for abortion, although the underline mechanism was not elucidated. In the present study, all placentas analysed from ewes suffering acute phase abortions showed infarcts and thrombosis in the caruncullar villi of the placentomes and ischemic lesions (periventricular leukomalacia) in the brain of some foetuses. The parasite was identified by PCR in samples from some placentomes of only one sheep, and no antigen was detected by immunohistochemical labelling. These findings suggest that the vascular lesions found in the placenta, and the consequent hypoxic damage to the foetus, could be associated to the occurrence of acute phase abortions. Although the pathogenesis of these lesions remains to be determined, the infectious dose or virulence of the isolate may play a role in their development. PMID:24475786

    Chagas disease, caused by the intracellular protozoan Trypanosoma cruzi, is associated with inflammation, discomfort and pain during the acute phase. The influence of TNF-α (tumor necrosis factor) in this disease outcome is controversial. In this way, the aim of this work was to determine the role of the TNF-α blocker etanercept in the pain, discomfort, and survival during the Chagas' acute phase of mice experimentally infected with a wild virulent strain of T. cruzi. The infection with this wild strain was responsible for a severe visceral inflammation and said parasite showed a tropism in peritoneal fluid cells. Etanercept was able to restore spontaneous vertical and horizontal activities during the second week after infection and to abolish mechanical allodynia during the first week after infection. Finally, etanercept delayed the mortality without any effect on the parasitemia rates. This is the first report that correlates sickness behavior and allodynia with TNF-α and suggests that this cytokine may play an important role in the physiopathology of the acute phase.

    Psychological difficulties for patients seeking bariatric surgery are greater and in the post-operative phase, a significant minority go on to experience significant psychosocial difficulties, increasing their risk of poorer post-operative adjustment and associated weight regain. 17 post-operative patients participated in an eight-week cognitive behavioral therapy (CBT) based psychotherapy group at the Ottawa Hospital. A pre-post design with a 3-month follow-up investigated the impact of the group on emotional eating, general as well as obesity-specific adjustment, psychological distress, and attachment. There were significant and meaningful improvements in patients' level of psychological distress, perceived difficulties in their lives, and weight-related adjustment that were maintained at a 3-month follow-up period. Although statistical change was not significant, there were also meaningful improvements in emotional overeating and relationship anxiety and avoidance. The intervention also appeared to be acceptable to patients in that attendance and satisfaction were good. Findings suggest that a short-term CBT psychotherapy group led to significant and meaningful benefits in psychological wellbeing for post-surgical bariatric patients.

    Aortic valve injury due to blunt trauma is rare and often difficult to diagnose. Therefore, most reported cases are operated on months or years after initial injury. Reported below is the case of a 55-year-old male, who was involved in a head-on collision with a bus. He was transported to Tsukuba Medical Center by ambulance, 34 minutes after the accident. The patient presented acute shock without obvious evidence of hemorrhaging. On physical examination a murmur was detected. The murmur was evaluated by Doppler echocardiography and revealed aortic regurgitation. On further physical examination he had gross hematuria and intratracheal bleeding. Computerized tomography (CT) showed evidence of contusions to his lungs, liver, and kidneys. The individual was diagnosed with an aortic valve injury, causing aortic insufficiency. It was necessary to continuously monitor the patients' hemodynamic state, assessing when conditions to operate were most favorable. However, in the hyper-acute phase the bleeding is difficult to control. We waited for his platelet count to recover before operating on the fifth day. When the patient underwent valve repair using extracorporeal circulation (ECC), aprotinin was added to the procedure. The surgery revealed a large laceration on the right coronary cusp of the aortic valve. Repair to the valve was impossible, so replacement of the aortic valve was required. A Carbomedics mechanical valve (phi 21 mm) was inserted. The patient did well after surgery, and eventually returned to work. To date, in Japan, there are eleven such cases of aortic valve injury on file. However, this is the first reported case that involved operating during the acute phase. This case demonstrates that, with careful evaluation of coexisting injuries and control of bleeding, successful treatment of aortic valve injury using ECC is possible, even in the acute phase.

    The aim of this study was to evaluate the role of butyrylcholinesterase (BChE) as a marker of inflammation and liver injury in the acute and subclinical phases of canine ehrlichiosis. Forty-two serum samples of dogs naturally infected with Ehrlichia canis were used, of which 24 were from animals with the acute phase of the disease and 18 with subclinical disease. In addition, sera from 17 healthy dogs were used as negative controls. The hematocrit, BChE activity, hepatic injury (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), nitric oxide, and cytokines levels were evaluated. The BChE activity was significantly elevated (P<0.05) in dogs with the acute phase of the disease when compared to healthy animals. However, there was a reduction on BChE activity on dogs with subclinical disease compared to the other two groups. AST and ALT levels were significantly higher (P<0.05) in the acute phase, as well as the inflammatory mediators (NOx, TNF-α, INF-γ, IL-4, IL-6) when compared to the control group. On the other hand, IL-10 levels were lower in the acute phase. Based on these results, we are able to conclude that the acute infection caused by E. canis in dogs leads to an increase on seric BChE activity and some inflammatory mediators. Therefore, this enzyme might be used as a marker of acute inflammatory response in dogs naturally infected by this bacterium. PMID:26616656

    Background To differentiate the features of electroencephalography (EEG) after status epileptics in febrile children with final diagnosis of either febrile seizure (FS) or acute encephalopathy for an early diagnosis. Methods We retrospectively collected data from 68 children who had status epilepticus and for whom EEGs were recorded within 120 h. These included subjects with a final diagnosis of FS (n = 20), epileptic status (ES; n = 11), acute encephalopathy with biphasic seizures and late reduced diffusion (AESD; n = 18), mild encephalopathy with a reversible splenial lesion (MERS; n = 7), other febrile encephalopathies (n = 10), hypoxic-ischemic encephalopathy (n = 1), and intracranial bleeding (n = 1). Initially, all EEGs were visually assessed and graded, and correlation with outcome was explored. Representative EEG epochs were then selected for quantitative analyses. Furthermore, data from AESD (n = 7) and FS (n = 16) patients for whom EEG was recorded within 24 h were also compared. Results Although milder and most severe grades of EEG correlated with neurological outcome, the outcome of moderate EEG severity group was variable and was not predictable from usual inspection. Frequency band analysis revealed that solid delta power was not significantly different among the five groups (AESD, MERS, FS, ES and control), and that MERS group showed the highest theta band power. The ratios of delta/alpha and (delta + theta)/(alpha + beta) band powers were significantly higher in the AESD group than in other groups. The alpha and beta band powers in EEGs within 24 h from onset were significantly lower in the AESD group. The band powers and their ratios showed earlier improvement towards 24 h in FS than in AESD. Conclusion Sequential EEG recording up to 24 h from onset appeared to be helpful for distinction of AESD from FS before emergence of the second phase of AESD. PMID:27046946

    To clarify the molecular changes of sublesional muscle in the acute phase of spinal cord injury (SCI), a moderately severe injury (40 g cm) was induced in the spinal cord (T10 vertebral level) of adult male Sprague-Dawley rats (injury) and compared with sham (laminectomy only). Rats were sacrificed at 48 h (acute) post injury, and gastrocnemius muscles were excised. Morphological examination revealed no significant changes in the muscle fiber diameter between the sham and injury rats. Western blot analyses performed on the visibly red, central portion of the gastrocnemius muscle showed significantly higher expression of muscle specific E3 ubiquitin ligases (muscle ring finger-1 and muscle atrophy f-box) and significantly lower expression of phosphorylated Akt-1/2/3 in the injury group compared to the sham group. Cyclooxygenase 2, tumor necrosis factor alpha (TNF-α), and caspase-1, also had a significantly higher expression in the injury group; although, the mRNA levels of TNF-α and IL-6 did not show any significant difference between the sham and injury groups. These results suggest activation of protein degradation, deactivation of protein synthesis, and development of inflammatory reaction occurring in the sublesional muscles in the acute phase of SCI before overt muscle atrophy is seen.

    Fibrinogen-like protein 1 (FGL1) is a hepatocyte derived protein that is upregulated in regenerating rodent livers following partial hepatectomy. It has been implicated as a mitogen for liver cell proliferation. In this study, we show that recombinant human IL-6 induces FGL1 expression in Hep G2 cells in a pattern similar to those of acute phase reactants. Following induction of acute inflammation in rats by subcutaneous injection of turpentine oil, serum FGL1 levels are also enhanced. Although, a recent report suggests that FGL1 associates almost exclusively with the fibrin matrix, we report here that approximately 20% of the total plasma FGL1 remains free. The enhancement of FGL1 levels in vitro by IL-6 and its induction after turpentine oil injection suggest that it is an acute phase reactant. Its presence in bound and free forms in the blood also implies biological roles that extend beyond the proposed autocrine effect it has on hepatocytes during regeneration.

    OBJECTIVE: The aim of this study was to assess the pulmonary function of children with acute leukemia. METHODS: Cross-sectional observational analytical study that enrolled 34 children divided into groups A (17 with acute leukemia in the maintenance phase of chemotherapy) and B (17 healthy children). The groups were matched for sex, age and height. Spirometry was measured using a spirometer Microloop Viasys(r) in accordance with American Thoracic Society and European Respiratory Society guidelines. Maximal respiratory pressures were measured with an MVD300 digital manometer (Globalmed(r)). Maximal inspiratory pressures and maximal expiratory pressures were measured from residual volume and total lung capacity, respectively. RESULTS: Group A showed a significant decrease in maximal inspiratory pressures when compared to group B. No significant difference was found between the spirometric values of the two groups, nor was there any difference between maximal inspiratory pressure and maximal expiratory pressure values in group A compared to the lower limit values proposed as reference. CONCLUSION: Children with acute leukemia, myeloid or lymphoid, during the maintenance phase of chemotherapy exhibited unchanged spirometric variables and maximal expiratory pressure; However, there was a decrease in inspiratory muscle strength.

    After patients with major depressive disorder (MDD) respond to acute-phase cognitive therapy (CT), continuation-phase treatments may be applied to improve long-term outcomes. We clarified which CT responders experience remission, recovery, relapse, and recurrence by testing baseline demographic, clinical, and personality variables. The sample of CT responders at higher risk of relapse (N = 241) was randomized to 8 months of continuation-phase CT, double-blinded fluoxetine, or pill placebo, and followed 24 months (Jarrett & Thase, 2010). Patients with lower positive emotionality and behavioral activation at the end of acute-phase CT showed increased risk for relapse/recurrence of MDD. In addition, patients with lower positive emotionality and behavioral activation, as well as higher residual depression (including emotional, cognitive, and social facets), showed decreased probability of remission (≥6 continuous weeks of minimal or absent symptoms) after acute-phase CT. Finally, patients with greater residual depression, as well as younger age and earlier MDD onset, showed decreased probability of recovery (≥35 continuous weeks of minimal or absent symptoms) after acute-phase CT. Moderator analyses did not reveal differential prediction across the continuation phase treatment arms. These results may help clinicians gauge the prognoses and need for continuation treatment among MDD patients who respond to acute-phase CT.

    During an acute viral infection, virus levels rise, reach a peak and then decline. Data and numerical solutions suggest the growth and decay phases are linear on a log scale. While viral dynamic models are typically nonlinear with analytical solutions difficult to obtain, the exponential nature of the solutions suggests approximations can be found. We derive a two-phase approximate solution to the target cell limited influenza model and illustrate the accuracy using data and previously established parameter values of six patients infected with influenza A. For one patient, the subsequent fall in virus concentration was not consistent with our predictions during the decay phase and an alternate approximation is derived. We find expressions for the rate and length of initial viral growth in terms of the parameters, the extent each parameter is involved in viral peaks, and the single parameter responsible for virus decay. We discuss applications of this analysis in antiviral treatments and investigating host and virus heterogeneities.

    A cohort of 76 patients with acute myocardial infarction was studied with infarct-avid scan, radionuclide ventriculography, and thallium-201 myocardial perfusion scintigraphy. Infarct area, left ventricular ejection fraction, and defect score were calculated as radionuclide indices of the extent of myocardial infarction. The correlation was studied between these indices and cardiac events (death, congestive heart failure, postinfarction angina, and recurrence of myocardial infarction) in the first postinfarction year. High-risk patients (nonsurvivors and patients who developed heart failure) had a larger infarct area, a lower left ventricular ejection fraction, and a larger defect score than the others. Univariate linear discriminant analysis was done to determine the optimal threshold of these parameters for distinguishing high-risk patients from others. Radionuclide parameters obtained in the early phase of acute myocardial infarction were useful for detecting both patients with grave complications and those with poor late prognosis during a mean follow-up period of 2.6 years.

    Purpose: Hypofractionated radiation therapy (RT) in prostate cancer can be developed only if the risk of rectal toxicity is controlled. In a multicenter phase 2 trial, hypofractionated irradiation was combined with an injection of hyaluronic acid (HA) to preserve the rectal wall. Tolerance of the injection and acute toxicity rates are reported. Methods and Materials: The study was designed to assess late grade 2 toxicity rates. The results described here correspond to the secondary objectives. Acute toxicity was defined as occurring during RT or within 3 months after RT and graded according to the Common Terminology Criteria for Adverse Events version 4.0. HA tolerance was evaluated with a visual analog scale during the injection and 30 minutes after injection and then by use of the Common Terminology Criteria at each visit. Results: From 2010 to 2012, 36 patients with low-risk to intermediate-risk prostate cancer were included. The HA injection induced a mean pain score of 4.6/10 ± 2.3. Thirty minutes after the injection, 2 patients still reported pain (2/10 and 3/10), which persisted after the intervention. Thirty-three patients experienced at least 1 acute genitourinary toxicity and 20 patients at least 1 acute gastrointestinal toxicity. Grade 2 toxicities were reported for 19 patients with urinary obstruction, frequency, or both and for 1 patient with proctitis. No grade 3 or 4 toxicities were reported. At the 3-month visit, 4 patients described grade 2 obstruction or frequency, and no patients had any grade 2 gastrointestinal toxicities. Conclusions: The injection of HA makes it possible to deliver hypofractionated irradiation over 4 weeks with a dose per fraction of > 3 Gy, with limited acute rectal toxicity.

    Identification of biomarkers assists in the diagnosis of disease and the assessment of health risks from environmental exposures. We hypothesized that rats exposed to Libby amphibole (LA) would present with a unique serum proteomic profile which could help elucidate epidemiologically-relevant biomarkers. In four experiments spanning varied protocols and temporality, healthy (Wistar Kyoto, WKY; and F344) and cardiovascular compromised (CVD) rat models (spontaneously hypertensive, SH; and SH heart failure, SHHF) were intratracheally instilled with saline (control) or LA. Serum biomarkers of cancer, inflammation, metabolic syndrome (MetS), and the acute phase response (APR) were analyzed. All rat strains exhibited acute increases in α-2-macroglobulin, and α1-acid glycoprotein. Among markers of inflammation, lipocalin-2 was induced in WKY, SH and SHHF and osteopontin only in WKY after LA exposure. While rat strain- and age-related changes were apparent in MetS biomarkers, no LA effects were evident. The cancer marker mesothelin was increased only slightly at 1 month in WKY in one of the studies. Quantitative Intact Proteomic profiling of WKY serum at 1 day or 4 weeks after 4 weekly LA instillations indicated no oxidative protein modifications, however APR proteins were significantly increased. Those included serine protease inhibitor, apolipoprotein E, α-2-HS-glycoprotein, t-kininogen 1 and 2, ceruloplasmin, vitamin D binding protein, serum amyloid P, and more 1 day after last LA exposure. All changes were reversible after a short recovery regardless of the acute or long-term exposures. Thus, LA exposure induces an APR and systemic inflammatory biomarkers that could have implications in systemic and pulmonary disease in individuals exposed to LA. -- Highlights: ► Biomarkers of asbestos exposure are required for disease diagnosis. ► Libby amphibole exposure is associated with increased human mortality. ► Libby amphibole increases circulating proteins involved

    Using nuclear isotopic imaging, digital circulation was sequentially evaluated at 24-hour intervals in 11 control horses and in 9 horses affected with acute laminitis, created by administration of a high-starch ration. Following intra-arterial injection of /sup 99m/Tc macroaggregated albumin into the brachiocephalic trunk, a gamma camera and dedicated nuclear medicine computer were used to acquire static images of the right front foot. Dynamic vascular-phase and static interstitial-phase images were also obtained after jugular vein injection of /sup 99m/Tc diethylenetriamine pentaacetic acid. These procedures were performed on standing horses, using either minimal or no tranquilization. The images were quantitatively analyzed for parameters indicative of circulation to the foot as a whole and to specific regions of interest within the foot. There was no evidence of reduced total blood flow to the lamellae during either the developmental or acute phases of laminitis. Although total flow tended to increase throughout the peripheral/external regions of the foot, statistically significant elevations were consistently present only within the lamellae. Changes indicative of decreased total blood flow were noted in the central/internal regions of the foot. These alterations usually occurred coincident with or after the onset of clinical lameness.

    To review the evidence of thromboembolism incidence and prophylaxis in the sub-acute phase of spinal cord injury (SCI) 3–6 months post injury. All observational and experimental studies with any length of follow-up and no limitations on language or publication status published up to March 2015 were included. Two review authors independently selected trials for inclusion and extracted data. Outcomes studied were incidence of pulmonary embolism (PE) and deep vein thrombosis (DVT) in the sub-acute phase of SCI. The secondary outcome was type of thromboprophylaxis. Our search identified 4305 references and seven articles that met the inclusion criteria. Five papers reported PE events and three papers reported DVT events in the sub-acute phase of SCI. Studies were heterogeneous in populations, design and outcome reporting, therefore a meta-analysis was not performed. The included studies report a PE incidence of 0.5%–6.0% and DVT incidence of 2.0%–8.0% in the sub-acute phase of SCI. Thromboprophylaxis was poorly reported. Spinal patients continue to have a significant risk of PE and DVT after the acute period of their injury. Clinicians are advised to have a low threshold for suspecting venous thromboembolism in the sub-acute phase of SCI and to continue prophylactic anticoagulation therapy for a longer period of time.

    Purpose Transient global amnesia (TGA) is a transitory, short-lasting neurological disorder characterized by a sudden onset of antero- and retrograde amnesia. Perfusion abnormalities in TGA have been evaluated mainly by use of positron emission tomography (PET) or single-photon emission computed tomography (SPECT). In the present study we explore the value of dynamic susceptibility contrast perfusion-weighted MRI (PWI) in TGA in the acute phase. Methods From a MRI report database we identified TGA patients who underwent MRI including PWI in the acute phase and compared these to control subjects. Quantitative perfusion maps (cerebral blood flow (CBF) and volume (CBV)) were generated and analyzed by use of Signal Processing In NMR-Software (SPIN). CBF and CBV values in subcortical brain regions were assessed by use of VOI created in FIRST, a model-based segmentation tool in the Oxford Centre for Functional Magnetic Resonance Imaging of the Brain (FMRIB) Software Library (FSL). Results Five TGA patients were included (2 men, 3 women). On PWI, no relevant perfusion alterations were found by visual inspection in TGA patients. Group comparisons for possible differences between TGA patients and control subjects showed significant lower rCBF values bilaterally in the hippocampus, in the left thalamus and globus pallidus as well as bilaterally in the putamen and the left caudate nucleus. Correspondingly, significant lower rCBV values were observed bilaterally in the hippocampus and the putamen as well as in the left caudate nucleus. Group comparisons for possible side differences in rCBF and rCBV values in TGA patients revealed a significant lower rCBV value in the left caudate nucleus. Conclusions Mere visual inspection of PWI is not sufficient for the assessment of perfusion changes in TGA in the acute phase. Group comparisons with healthy control subjects might be useful to detect subtle perfusion changes on PWI in TGA patients. However, this should be confirmed in

    Migratory birds have been implicated in the spread of some zoonotic diseases, but how well infected individuals can fly remains poorly understood. We used western sandpipers, Calidris mauri, to experimentally test whether flight is affected when long-distance migrants are mounting an immune response and whether migrants maintain immune defences during a flight in a wind tunnel. We measured five indicators of innate immunity in 'flown-healthy' birds (flying in a wind tunnel without mounting an immune response), 'flown-sick' birds (flying while mounting an acute phase response, which is part of induced innate immunity), and a non-flying control group ('not-flown'). Voluntary flight duration did not differ between flown-healthy and flown-sick birds, indicating that mounting an acute phase response to simulated infection did not hamper an individual's ability to fly for up to 3 h. However, in comparison to not-flown birds, bacterial killing ability of plasma was significantly reduced after flight in flown-sick birds. In flown-healthy birds, voluntary flight duration was positively correlated with bacterial killing ability and baseline haptoglobin concentration of the blood plasma measured 1-3 weeks before experimental flights, suggesting that high quality birds had strong immune systems and greater flight capacity. Our findings indicate that flight performance is not diminished by prior immune challenge, but that flight while mounting an acute phase response negatively affects other aspects of immune function. These findings have important implications for our understanding of the transmission of avian diseases, as they suggest that birds can still migrate while fighting an infection.

    A 42-kDa protein appeared at a much higher concentration in plasma from Trypanosoma brucei-resistant (C57BL/6) mice after infection than in plasma from trypanosome-susceptible (C3H/He) mice. This protein was purified by sequential steps of gel filtration, protein A-Sepharose affinity chromatography, isoelectric focusing, and ammonium sulfate precipitation. The purified protein was identified as a subunit of the acute-phase reactant haptoglobin. Causes of elevated plasma haptoglobin and its implications for resistance to trypanosomiasis are discussed.

  15. Lack of association of acute phase response proteins with hormone levels and antidepressant medication in perimenopausal depression

    PubMed Central

    2014-01-01

    Background Major depression is associated with higher plasma levels of positive acute-phase proteins, as well as with lower plasma levels of negative acute-phase proteins. The aim of this study is to examine the levels of acute-phase response proteins and whether these levels are influenced by reproductive hormones and antidepressant medication in the perimenopausal depression. Methods Sixty-five women (age range: 40–58 years old) participated in this study. All women were in the perimenopausal phase. The diagnosis of depression was made through a psychiatric interview and with the aid of Hamilton Depression Rating Scale 17 (HAM-D 17). The acute-phase response proteins, such as haptoglobin (HP), transferrine (TRf), α1-antitrypsin, complement protein 3 (C3), complement protein 4 (C4) and C-reactive protein (CRP) and the reproductive hormones, for example follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2), were analyzed using standard laboratory methods. Pearson’s correlations were applied to evaluate the relationship between acute-phase proteins and hormones. Results Perimenopausal women were divided into three groups. The first group consisted of normal controls, the second one involved depressed perimenopausal women, who were taking selective serotonin reuptake inhibitors (SSRIs), and the third one included depressed women that were not treated with SSRIs. Depressed women in perimenopause, when being compared to non-depressed women, did not differ as to serum levels of acute-phase proteins. There was a positive correlation between HP and E2 in depressed perimenopausal women, who were not taking SSRIs. Conclusions The lack of association between acute-phase proteins and depressive mood mentioned in this study does not support previous findings in patients with major depression. This negative finding in perimenopausal depression indicates either the absence or a more complex nature of the interactions between acute-phase proteins

    Zika virus is an emerging mosquito-borne flavivirus currently causing large epidemics in the Pacific Ocean region and Brazil. Clinically, Zika fever resembles dengue fever, but is less severe. Whereas the clinical syndrome and laboratory diagnostic procedures have been described, little attention was paid to the immunology of the disease and its possible use for clinical follow-up of patients. Here, we investigate the role of cytokines in the pathogenesis of Zika fever in travelers returning from Asia, the Pacific, and Brazil. Polyfunctional T cell activation (Th1, Th2, Th9, and Th17 response) was seen during the acute phase characterized by respective cytokine level increases, followed by a decrease in the reconvalescent phase.

    Women often exhibit larger hormonal and subjective responses to opioid receptor antagonists than men, but the biological mechanisms mediating this effect remain unclear. Among women, fluctuations in estradiol (E2) and progesterone (P4) across the menstrual cycle (MC) affect the endogenous opioid system. Therefore, the goal of the current study was to compare acute naltrexone response between women in the early follicular phase of the MC (low E2 and P4), women in the luteal phase of the MC (high E2 and P4), and men. Seventy healthy controls (n = 46 women) participated in two morning sessions in which they received 50 mg naltrexone or placebo in a randomized, counterbalanced order. Women were randomized to complete both sessions in either the early follicular (n = 23) or luteal phase of the MC. Serum cortisol, prolactin, and luteinizing hormone (LH), salivary cortisol, and subjective response were assessed upon arrival to the laboratory and at regular intervals after pill administration. In luteal and early follicular women but not men, naltrexone (vs. placebo) increased serum cortisol and prolactin levels from baseline; however, the naltrexone-induced increases in these hormones were significantly greater in luteal women than early follicular women. Additionally, only luteal women demonstrated an increase from baseline in salivary cortisol levels and the severity of adverse drug effects in response to naltrexone. In sum, the results indicate that luteal phase women are more sensitive to acute hormonal and subjective effects of naltrexone than early follicular women and men. These findings may have important implications for the use of naltrexone in women. PMID:25459893

    Infection of Asian elephants (Elephas maximus) with elephant endotheliotropic herpesvirus (EEHV) can be associated with rapid, lethal hemorrhagic disease and has been documented in elephant herds in human care and in the wild. Recent reports describe real-time quantitative polymerase chain reaction (qPCR) assays used to monitor clinically ill elephants and also to detect subclinical EEHV1 infection in apparently healthy Asian elephants. Acute phase proteins have been demonstrated to increase with a variety of infectious etiologies in domesticated mammals but have not yet been described in elephants. In addition, the immune response of Asian elephants to EEHV1 infection has not been described. In this study, whole blood and trunk wash samples representing repeated measures from eight elephants were examined for the presence of EEHV1 using a qPCR assay. Elephants were classified into groups, as follows: whole blood negative and positive and trunk wash negative and positive. Serum amyloid A (SAA) and haptoglobin (HP) levels were compared between these groups. A significant difference in SAA was observed with nearly a threefold higher mean value during periods of viremia (P=0.011). Higher values of SAA were associated with >10,000 virus genome copies/ml EEHV1 in whole blood. There were no significant differences in HP levels, although some individual animals did exhibit increased levels with infection. These data indicate that an inflammatory process is stimulated during EEHV1 viremia. Acute phase protein quantitation may aid in monitoring the health status of Asian elephants.

  19. HIV infection and drugs of abuse: role of acute phase proteins

    PubMed Central

    2013-01-01

    Background HIV infection and drugs of abuse such as methamphetamine (METH), cocaine, and alcohol use have been identified as risk factors for triggering inflammation. Acute phase proteins such as C-reactive protein (CRP) and serum amyloid A (SAA) are the biomarkers of inflammation. Hence, the interactive effect of drugs of abuse with acute phase proteins in HIV-positive subjects was investigated. Methods Plasma samples were utilized from 75 subjects with METH use, cocaine use, alcohol use, and HIV-positive alone and HIV-positive METH, cocaine, and alcohol users, and age-matched control subjects. The plasma CRP and SAA levels were measured by ELISA and western blot respectively and the CD4 counts were also measured. Results Observed results indicated that the CRP and SAA levels in HIV-positive subjects who are METH, cocaine and alcohol users were significantly higher when compared with either drugs of abuse or HIV-positive alone. The CD4 counts were also dramatically reduced in HIV-positive with drugs of abuse subjects compared with only HIV-positive subjects. Conclusions These results suggest that, in HIV-positive subjects, drugs of abuse increase the levels of CRP and SAA, which may impact on the HIV infection and disease progression. PMID:24044608

    The orphan nuclear receptor liver receptor homolog 1 (LRH-1) has been reported to play an important role in bile acid biosynthesis and reverse cholesterol transport. Here, we show that LRH-1 is a key player in the control of the hepatic acute-phase response. Ectopic expression of LRH-1 with adenovirus resulted in strong inhibition of both interleukin-6 (IL-6)- and IL-1beta-stimulated haptoglobin, serum amyloid A, and fibrinogen beta gene expression in hepatocytes. Furthermore, induction of the hepatic inflammatory response was significantly exacerbated in HepG2 cells expressing short hairpin RNA targeting LRH-1 expression. Moreover, transient-transfection experiments and electrophoretic mobility shift and chromatin immunoprecipitation assays revealed that LRH-1 regulates this cytokine-elicited inflammatory response by, at least in part, antagonizing the CCAAT/enhancer binding protein beta signaling pathway. Finally, we show, by using LRH-1 heterozygous mice, that LRH-1 is involved in the control of the inflammatory response at the hepatic level in vivo. Taken together, our results outline an unexpected role for LRH-1 in the modulation of the hepatic acute-phase response.

    The extent of inflammation associated with tail biting in finishing pigs was evaluated. Tail histopathology, carcass condemnation and the concentration of three acute phase proteins (APPs), C-reactive protein (CRP), serum amyloid-A (SAA) and haptoglobin (Hp), were examined in 12 tail-bitten and 13 control pigs. The median concentrations of APPs were higher (P<0.01) in bitten (CRP 617.5mg/L, range 80.5-969.9; SAA 128.0mg/L, 6.2-774.4; Hp 2.8g/L, 1.6-3.5) than in control pigs (CRP 65.7mg/L, 28.4-180.4; SAA 6.2mg/L, 6.2-21.4; Hp 1.2g/L, 0.9-1.5). There was a tendency for APP concentrations to rise with the histopathological score but the differences were only statistically significant between some of the scores. Five (42%) bitten cases and one (8%) control pig had partial carcass condemnations owing to abscesses (P=0.07). The results show that tail biting induces an inflammatory response in the tail end leading to an acute phase response and formation of carcass abscesses. PMID:19398209

    Chemotherapy remains the first-choice option for adjuvant therapy in breast cancer. Here, we investigated the impact of the first chemotherapic cycle of doxorubicin on the plasmatic-proteomic profiling of women diagnosed with breast cancer (n = 87). Blood samples were obtained from the same patient before and after doxorubicin infusion (1 h, 60 mg/m(2)) and processed for label-free LC-MS proteomic screening. A total of 80 proteins were downregulated after chemotherapy. In silico analysis revealed that the main biological process enrolled was inflammation and canonical pathways involving acute phase proteins. TNF-α, IL-1β, IL-12, TGF-β1, clusterin, and gelsolin were chosen as relevant for further validation. All selected targets presented reduced plasmatic levels after treatment. Our results indicate that doxorubicin downregulated acute phase proteins immediately after its infusion. Since such proteins are cancer promoting, its downregulation could support the effectiveness of doxorubicin along treatment. PMID:26472721

    Background. The platelet parameters and C-reactive protein (CRP) are markers reflecting a systemic inflammatory response. Among those, CRP is one of the major proteins helpful in determination of severity/activity of chronic spontaneous urticaria (CSU). Aim. To determine relationships between platelet activation indices and serum concentration of CRP, the best marker of acute phase response, and their potential clinical use in CSU patients. Methods. Mean platelet volume (MPV), platelet distribution width (PDW), and platelet count as well as serum CRP concentration were measured in CSU patients, showing different degrees of urticarial severity, and in the healthy subjects. Results. No significant differences were found in MPV and PDW between CSU group and the healthy subjects. The platelet count was significantly higher in moderate-severe CSU than that of the controls and mild CSU patients. Serum CRP concentrations were significantly higher in CSU patients as compared with the healthy subjects and significantly correlated with the platelet count in CSU patients. Conclusions. Acute phase response in CSU is associated with the increased number of circulating platelets in patients with more severe symptoms. It seems that simple determination of platelet size indices is not a reliable indicator of CSU severity/activity. PMID:25025065

    The aims of this study were to investigate the level of acute phase proteins in dairy cows with urinary tract infection (UTI) and to evaluate their diagnostic and prognostic value. Eighty-four lactating cows with clinical and laboratory evidence of UTI and 15 healthy controls were included in this study. Serum samples were evaluated for the levels of Haptoglobin (Hp), serum amyloid A (SAA), fibrinogen (Fb), α1-Acid glycoprotein (AGP), total protein, and globulin. The diagnostic and prognostic performance of each parameter was evaluated by estimating the area under receiver operating characteristics curve (AUROC). Escherichia coli and Corynebacterium spp. were the primary bacteria associated with UTI. The levels of serum Hp, SAA, Fb, AGP, total protein, and globulin were significantly higher in UTI cows. Successfully treated cows (n = 51) had lower levels of Hp, SAA, AGP, total protein, and globulin than non-responsive cows. Overall, Hp, SAA, Fb, and AGP showed comparable diagnostic accuracy (AUROC ranged from 0.93 to 0.98). Both Hp and SAA showed high accuracy in predicting treatment response (AUROC > 0.95), whereas Fb level was of no prognostic value (AUROC = 0.48). From this study, acute phase proteins levels can be used as markers for UTI in cows and higher levels of Hp, SAA and AGP are related to poor treatment response. PMID:27348889

    Protein electrophoresis has recognized applications in determining the health status of various species. While reference intervals for electrophoresis have been determined for psittacine and raptor species, there are none reported for Phoenicopteriformes species. Reference intervals for haptoglobin and protein fractions obtained by electrophoresis were determined for the American flamingo (Phoenicopterus ruber) based on plasma samples from 39 captive birds. The reference intervals were as follows: haptoglobin, 0.17-0.8 mg/ml; total protein, 3.65-6.38 g/dl; prealbumin, 0.26-1.9 g/dl; albumin, 1.51-3.12 g/dl; α-1 globulin, 0.06-0.38 g/dl; α-2 globulin, 0.17-0.67 g/dl; β globulin, 0.38-1.33 g/dl; γ globulin, 0.26-0.68 g/dl; albumin : globulin ratio, 0.93-2.17. As captive flamingos often suffer from pododermatitis, feet of all flamingos were scored to determine if pododermatitis would be reflected in the acute phase proteins. Spearman rank correlation was performed on each of the protein fractions and pododermatitis scores, and only albumin had a significant correlation. This indicates that albumin, as a negative acute phase protein, may be a marker for this disease process.

    2016-03-15

    Pentraxin-3 (PTX3) is an acute phase protein (APP) and a member of the long pentraxin family that is recognised for its role in peripheral immunity and vascular inflammation in response to injury, infection and diseases such as atherosclerosis, cancer and respiratory disease. Systemic levels of PTX3 are highly elevated in these conditions, and PTX3 is now recognised as a new biomarker of disease risk and progression. There is extensive evidence demonstrating that central nervous system (CNS) disorders are primarily characterised by central activation of innate immunity, as well as activation of a potent peripheral acute phase response (APR) that influences central inflammation and contributes to poor outcome. PTX3 has been recently recognised to play important roles in CNS disorders, having both detrimental and neuroprotective effects. The present review aims to give an up-to-date account of the emerging roles of PTX3 in CNS disorders, and to provide a critical comparison between peripheral and central actions of PTX3 in inflammatory diseases.

    Infection and undernutrition are prevalent in developing countries and demonstrate a synergistic relation. Undernutrition increases infection-related morbidity and mortality. The acute phase response (APR) is an innate, systemic inflammatory reaction to a wide array of disruptions in a host’s homeostasis, including infection. Released from immune cells in response to deleterious stimuli, proinflammatory cytokines act on distant tissues to induce behavioral (e.g., anorexia, weakness, and fatigue) and systemic effects of the APR. Cytokines act to increase energy and protein requirements to manifest fever and support hepatic acute phase protein (APP) production. Blood concentrations of glucose and lipid are augmented to provide energy to immune cells in response to cytokines. Additionally, infection decreases intestinal absorption of nutrients and can cause direct loss of micronutrients. Traditional indicators of iron, zinc, and vitamin A status are altered during the APR, leading to inaccurate estimations of deficiency in populations with a high or unknown prevalence of infection. Blood concentrations of APPs can be measured in nutrition interventions to assess the time stage and severity of infection and correct for the APR; however, standardized cutoffs for nutrition applications are needed. Protein-energy malnutrition leads to increased gut permeability to pathogens, abnormal immune cell populations, and impaired APP response. Micronutrient deficiencies cause specific immune impairments that affect both innate and adaptive responses. This review describes the antagonistic interaction between the APR and nutritional status and emphasizes the need for integrated interventions to address undernutrition and to reduce disease burden in developing countries.

    OBJECTIVE To test cognitive behavioral therapy for adherence and depression (CBT-AD) in type 2 diabetes. We hypothesized that CBT-AD would improve adherence; depression; and, secondarily, hemoglobin A1c (A1C). RESEARCH DESIGN AND METHODS Eighty-seven adults with unipolar depression and uncontrolled type 2 diabetes received enhanced treatment as usual (ETAU), including medication adherence, self-monitoring of blood glucose (SMBG), and lifestyle counseling; a provider letter documented psychiatric diagnoses. Those randomized to the intervention arm also received 9–11 sessions of CBT-AD. RESULTS Immediately after acute treatment (4 months), adjusting for baseline, CBT-AD had 20.7 percentage points greater oral medication adherence on electronic pill cap (95% CI −31.14 to −10.22, P = 0.000); 30.2 percentage points greater SMBG adherence through glucometer downloads (95% CI −42.95 to −17.37, P = 0.000); 6.44 points lower depression scores on the Montgomery-Asberg Depression Rating Scale (95% CI 2.33–10.56, P = 0.002); 0.74 points lower on the Clinical Global Impression (95% CI 0.16–1.32, P = 0.01); and 0.72 units lower A1C (95% CI 0.29–1.15, P = 0.001) relative to ETAU. Analyses of 4-, 8-, and 12-month follow-up time points indicated that CBT-AD maintained 24.3 percentage points higher medication adherence (95% CI −38.2 to −10.3, P = 0.001); 16.9 percentage points greater SMBG adherence (95% CI −33.3 to −0.5, P = 0.043); and 0.63 units lower A1C (95% CI 0.06–1.2, P = 0.03) after acute treatment ended. For depression, there was some evidence of continued improvement posttreatment, but no between-group differences. CONCLUSIONS CBT-AD is an effective intervention for adherence, depression, and glycemic control, with enduring and clinically meaningful benefits for diabetes self-management and glycemic control in adults with type 2 diabetes and depression.

The larger StAR transcript (4.4 kb) was found in early and midluteal phase CL, but was not detected in late luteal phase specimens. Mature StAR protein (30 kDa) was present in lower amounts within late CL compared with early and midluteal phase CL. The StAR preprotein (37 kDa) was also detected in greater abundance in early and midluteal CL. Immunohistochemistry revealed that StAR staining was most prominent in thecal-lutein cells throughout the luteal phase. The intensity of the signal for StAR exhibited significant changes throughout the luteal phase, being most intense during the midluteal phase and least during the late luteal phase. Plasma progesterone concentrations were highly correlated (r = 0.73 and r = 0.79) with luteal expression of the preprotein and mature StAR isoforms, respectively, throughout the luteal phase. To examine the LH dependency of StAR expression, the GnRH antagonist, Cetrorelix, was administered during the midluteal phase. Cetrorelix caused a decline in serum LH levels within 2 h, which, in turn, caused a pronounced decline in plasma progesterone within 6 h. The StAR 4.4-kb transcript was not detectable, and the 1.6-kb transcript was reduced by approximately 50% within 24 h of Cetrorelix treatment. The mature 30-kDa StAR protein level declined approximately 30% after Cetrorelix treatment. We conclude that 1) StAR mRNA and protein are highly expressed in early and midluteal phase CL; 2) StAR protein is present in both thecal-lutein and granulosa-lutein cells throughout the luteal phase; 3) StAR protein levels in the CL are highly correlated with plasma progesterone levels; 4) declining StAR mRNA and protein levels are characteristic of late luteal

    Objective In the current study, we compare measures of treatment outcome and engagement for Latino and non-Latino White patients receiving a cognitive-behavioral therapy (CBT) program delivered in primary care. Method Participants were 18–65 years old and recruited from 17 clinics at four different sites to participate in a randomized controlled trial for anxiety disorders, which compared the CALM intervention (consisting of CBT, medication, or both) to usual care. Of those participants who were randomized to the intervention arm and selected CBT (either alone or in combination with medication), 85 were Latino and 251 were non-Latino White; the majority of the Latino participants received the CBT intervention in English (n = 77). Blinded assessments of clinical improvement and functioning were administered at baseline, and at 6, 12, and 18 months after baseline. Measures of engagement, including attendance, homework adherence, understanding of CBT principles, and commitment to treatment were assessed weekly during the CBT intervention. Results Findings from propensity weighted linear and logistic regression models revealed no statistically significant differences between Latinos and non-Latino Whites on symptom measures of clinical improvement and functioning at almost all time points. There were significant differences on two of seven engagement outcomes, namely number of sessions attended and patients’ understanding of CBT principles. Conclusions These findings suggest that CBT can be an effective treatment approach for Latinos who are primarily English speaking and likely more acculturated, although continued attention should be directed toward engaging Latinos in such interventions.

    AIM: To study the effect of a new anti-CD163-dexamethasone conjugate targeting activated macrophages on the hepatic acute phase response in rats. METHODS: Wistar rats were injected intravenous with either the CD163 targeted dexamethasone-conjugate (0.02 mg/kg) or free dexamethasone (0.02 or 1 mg/kg) 24 h prior to lipopolysaccharide (LPS) (2.5 mg/kg intraperitoneal). We measured plasma concentrations of tumour necrosis factor-α (TNF-α) and interleukin 6 (IL-6) 2 h post-LPS and liver mRNAs and serum concentrations of the rat acute phase protein α-2-macroglobulin (α-2-M) 24 h after LPS. Also, plasma concentrations of alanine aminotransferase and bilirubin were measured at termination of the study. Spleen weight served as an indicator of systemic steroid effects. RESULTS: The conjugate halved the α-2-M liver mRNA (3.3 ± 0.6 vs 6.8 ± 1.1, P < 0.01) and serum protein (201 ± 48 μg/mL vs 389 ± 67 μg/mL, P = 0.04) after LPS compared to low dose dexamethasone treated animals, while none of the free dexamethasone doses had an effect on liver mRNA or serum levels of α-2-M. Also, the conjugate reduced TNF-α (7208 ± 1977 pg/mL vs 21583 ± 7117 pg/mL, P = 0.03) and IL-6 (15685 ± 3779 pg/mL vs 25715 ± 4036 pg/mL, P = 0.03) compared to the low dose dexamethasone. The high dose dexamethasone dose decreased the spleen weight (421 ± 11 mg vs 465 ± 12 mg, P < 0.05) compared to controls, an effect not seen in any other group. CONCLUSION: Low-dose anti-CD163-dexamethasone conjugate effectively decreased the hepatic acute phase response to LPS. This indicates an anti-inflammatory potential of the conjugate in vivo.

    Objective To determine the extent to which prospectively identified responders to cognitive therapy (CT) for recurrent major depressive disorder (MDD) hypothesized to be lower risk show significantly less relapse/recurrence than treated higher risk counterparts across 32 months. Method Outpatients (N = 523), aged 18–70, with recurrent MDD received 12–14 weeks of CT. The last seven consecutive scores from the Hamilton Rating Scale for Depression (HRSD-17), were used to stratify/define responders (n = 290) into lower (seven HRSD-17 scores of ≤ 6; n = 49; 17%) and higher risk (n = 241; 83%). The lower risk entered the 32-month follow-up. Higher risk patients were randomized to 8 months of continuation-phase CT or clinical management plus double-blind fluoxetine or pill placebo, with a 24-month follow-up. Results Lower risk patients were significantly less likely to relapse over the first 8 months compared to higher risk (Kaplan-Meier [KM] estimates (i.e., 4.9%=lower risk; 22.1%= higher risk; log-rank χ2 = 6.83, p = .009). This increased risk was attenuated, but not completely neutralized, by active continuation-phase therapy. Over the subsequent 24 months, the lower and higher risk groups did not differ in relapse/recurrence risk. Conclusions Rapid and sustained acute-phase CT remission identifies responders who do not require continuation-phase treatment to prevent relapse (i.e., return of an index episode). To prevent recurrence (i.e., new episodes), however, strategic allocation and more frequent “dosing” of CT and/or targeted maintenance-phase treatments may be required. Longitudinal follow-up is recommended. PMID:26654211

    Vascular disorders have a direct link to mortality in the acute phase of Trypanosoma cruzi infection. However, the underlying mechanisms of vascular dysfunction in this phase are largely unknown. We hypothesize that T. cruzi invades endothelial cells causing dysfunction in contractility and relaxation of the mouse aorta. Immunodetection of T. cruzi antigen TcRBP28 was observed in endothelial cells. There was a decreased endothelial nitric oxide synthase (eNOS)-derived NO-dependent vascular relaxation, and increased vascular contractility accompanied by augmented superoxide anions production. Endothelial removal, inhibition of cyclooxygenase 2 (COX-2), blockade of thromboxane A2 (TXA2) TP receptors, and scavenger of superoxide normalized the contractile response. COX-2, thromboxane synthase, inducible nitric oxide synthase (iNOS), p65 NFκB subunit and p22(phox) of NAD(P)H oxidase (NOX) subunit expressions were increased in vessels of chagasic animals. Serum TNF-α was augmented. Basal NO production, and nitrotyrosine residue expression were increased. It is concluded that T. cruzi invades mice aorta endothelial cells and increases TXA2/TP receptor/NOX-derived superoxide formation. Alongside, T. cruzi promotes systemic TNF-α increase, which stimulates iNOS expression in vessels and nitrosative stress. In light of the heart failure that develops in the chronic phase of the disease, to understand the mechanism involved in the increased contractility of the aorta is crucial.

    Traumatic brain injury (TBI) has been known to be the leading cause of breakdown and long-term disability in people under 45 years of age. This study highlights the effective factors on post-traumatic (PT) linguistic disorder and relations between linguistic and cognitive function after trauma in adults with acute TBI. A cross-sectional design was employed to study 60 post-TBI hospitalized adults aged 18-65 years. Post-traumatic (PT) linguistic disorder and cognitive deficit after TBI were respectively diagnosed using the Persian Aphasia Test (PAT) and Persian version of Mini-Mental State Examination (MMSE) at discharge. Primary post-resuscitation consciousness level was determined using the Glasgow Coma Scale (GCS). Paracilinical data was obtained by CT scan technique. Multiple logistic regression analysis illustrated that brain injury severity was the first powerful significant predictor of PT linguistic disorder after TBI and frontotemporal lesion was the second. It was also revealed that cognitive function score was significantly correlated with score of each language skill except repetition. Subsequences of TBI are more commonly language dysfunctions that demand cognitive flexibility. Moderate, severe and fronto-temporal lesion can increase the risk of processing deficit in linguistic macrostructure production and comprehension. The dissociation risk of cortical and subcortical pathways related to cognitive-linguistic processing due to intracranial lesions can augment possibility of lexical-semantic processing deficit in acute phase which probably contributes to later cognitive-communication disorder.

    The acute phase of venous thromboembolism (VTE) treatment focuses on the prompt and safe initiation of full-dose anticoagulation to decrease morbidity and mortality. Immediate management consists of resuscitation, supportive care, and thrombolysis for patients with haemodynamically significant pulmonary embolism (PE) or limb-threatening deep-vein thrombosis (DVT). Patients with contraindications to anticoagulants are considered for vena cava filters. Disposition for the acute treatment of VTE is then considered based on published risk scores and the patient's social status, as the first seven days carries the highest risk for VTE recurrence, extension and bleeding due to anticoagulation. Next, a review of: immediate and long-term bleeding risk, comorbidities (i. e. active cancer, renal failure, obesity, thrombophilia), medications, patient preference, VTE location and potential for pregnancy should be undertaken. This will help determine the most suitable anticoagulant for immediate treatment. The non-vitamin K antagonist oral anticoagulants (NOACs), including the factor Xa inhibitors apixaban, edoxaban and rivaroxaban as well as the direct-thrombin inhibitor dabigatran, are increasing the convenience of and options available for VTE treatment. Current options for immediate treatment include low-molecular-weight heparin (LMWH), unfractionated heparin (UFH), fondaparinux, apixaban, or rivaroxaban. LMWH or UFH may be continued as monotherapy or transitioned to treatment with a VKA, dabigatran or edoxaban. This review describes the upfront treatment of VTE and the evolving role of NOACs in the contemporary management of VTE.

  5. Molecular and cellular mechanisms used in the acute phase of stimulated steroidogenesis.

    PubMed

    Steroidogenic tissue can respond almost immediately to a stimulatory hormonal stimuli. Recent findings are shedding light on the molecular and cellular mechanisms that are used to synthesize and export steroid hormones in the acute phase of stimulation. In addition to utilising the cAMP intracellular messenger system to convey a stimulatory message, steroidogenic cells may employ the protein kinase C, arachidonic acid, tyrosine phosphate and nitrous oxide systems. It has been proposed that cholesterol laden vesicles travel along a network of intermediate filaments to reach the mitochondria. Cholesterol may then translocate from the outer mitochondrial membrane to the inner via sites of contact between the two membranes. These contact sites may be composed of protein bridges which include the constituents, porin, the benzodiazepine receptor and GTP binding proteins. Cholesterol is transported through the contact sites to the inner membrane and on reaching cytochrome P450 side chain cleavage (P450scc), cholesterol is converted to pregnenolone. Pregnenolone is in turn converted to a range of steroid hormones via enzyme casades. GTP binding proteins may regulate the contact site between the inner and outer membranes and thereby modulate cholesterol flux to P450scc. In the adrenal and gonads the rate that cholesterol traverses the contact point to reach the inner membrane is accelerated by the steroidogenic acute regulatory protein. Newly synthesized steroid hormones are transported to the cell periphery for export via a mechanism that may utilise an ion exchange protein.

    After a severe burn, the liver plays a pivotal role by modulating inflammatory processes, metabolic pathways, immune functions, and the acute phase response. Therefore, liver integrity and function are important for recovery. A thermal injury, however, causes hepatic damage by inducing hepatic edema, fatty infiltration, hepatocyte apoptosis, and metabolic derangements associated with insulin resistance and impaired insulin signaling. In preliminary studies, we found that these pathophysiological processes are related to hepatic inflammation, altered intracellular signaling, and mitochondrial dysfunction. We hypothesize that modulation of these processes with insulin could improve hepatic structure and function and, therefore, outcome of burned and critically ill patients. Insulin administration improves survival and decreases the rate of infections in severely burned and critically ill patients. Here, we show that insulin administration decreases the synthesis of proinflammatory cytokines and signal transcription factors and improves hepatic structure and function after a severe burn injury; insulin also restores hepatic homeostasis and improves hepatic dysfunction postburn via alterations in the signaling cascade.

    Estimation of the concentration of C9, C-reactive protein (CRP) and alpha1-antitrypsin in forty sera from patients with Behcet's syndrome and recurrent oral ulcers showed significantly increased amounts of C9 and CRP in Behcet's syndrome. The concentration of C9 was also significantly raised in recurrent oral ulceration, though to a lesser extent than in Behcet's syndrome. The assay C9 and CRP might be useful in the differential diagnosis of Behcet's syndrome, especially from recurrent oral ulcers. It is suggested that during epithelial inflammation in recurrent oral ulcers some of the acute phase proteins are increased and in some patients these may modulate the immunological mechanism in such a way as to induce a transition from focal oral ulceration to the multifocal Behcet's syndrome.

    Abstract Sudden sensorineural hearing loss (SSHL) is an otological emergency defined as a rapid hearing loss, seriously affects patient's social life. To data, no study has reported the treatment by acupuncture alone in the acute phase. In this report, Acupuncture and Moxibustion therapy of excitation-focus transfer is outlined. The patient was a 26-year-old young woman who had an SSHL coupled with ear fullness. The patient had no past medical history, but she had undergone variable emotions and had a history of excessive noise exposure. The patient refused to receive any medicine especially steroids and hyperbaric oxygen therapy. She just only received acupuncture treatment. Her symptoms and outcome measurements were improved every week and completely recovered after the last week. Even though the article presents a single case and is based on self-reports, there are very clear trends on how patients with SSHL responded to acupuncture treatments. PMID:27368045

    Elevated degree of body fatness and changes in other body composition parameters are known to be common effects of treatment for acute lymphoblastic leukemia (ALL) in children. In order to study peculiarities of somatic growth and development in ALL survivors, we describe the results of BIA body composition analysis of 112 boys and 108 girls aged 5-18 years in remission from ALL (remission time range 1-13 years) compared to data from the same number of age- and sex-matched healthy controls (n=220). Detrimental effect on height in ALL boys was observed, whereas girls experienced additional weight gain compared to healthy subjects. In ALL patients, resistance, body fat, and percent body fat were significantly increased. The reactance, phase angle, absolute and relative values of skeletal muscle and body cell mass were significantly decreased. Principal component analysis revealed an early prevalence of adiposity traits in the somatic growth and development of ALL girls compared to healthy controls.

    The aim of the study was to evaluate markers of the acute phase response (APR) in eventing horses by measuring acute phase proteins (APP) (haptoglobin, Hp, and serum amyloid A, SAA), lysozyme, protein adducts such as pentosidine-like adducts (PENT), malondialdehyde adducts (MDA), hydroxynonenal adducts (HNE) and total advanced glycation/glycoxidation end products (AGEs), complete blood count and lymphocyte subpopulations (CD4+, CD8+ and CD21+) both at rest and at the end of an eventing competition. Blood samples were collected from eight Warmblood horses (medium age 10 ± 3) during an official national 2-day event competition at rest (R) and 10 min after the arrival of the cross-country test on the second day. Exercise caused a significant increase in red blood cell number, haemoglobin, packed cell volume, neutrophils, white blood cell and lymphocyte number; however, these values remained within the normal range. The CD4+ and CD8+ cells significantly increased, whereas the CD21+ lymphocytes decreased; a significant increase in serum SAA, lysozyme and protein carbonyl derivates was also observed. Two-day event causes significant changes in APR markers such as lysozyme, protein carbonyl derivates (HNE, AGEs, PENT) and lymphocyte subpopulations. The data support the hypothesis that 2-day event may alter significantly APR markers. Limitations of the study were the relatively small sample size and sampling time conditioned by the official regulations of the event. Therefore, further studies are needed to investigate the time required for recovery to basal values in order to define the possible effects on the immune function of the athlete horse.

    The aim of this investigation was to evaluate how parental anxiety predicted change in pediatric anxiety symptoms across four different interventions: cognitive-behavioral therapy (CBT), medication (sertraline; SRT), their combination (COMB), and pill placebo. Participants were 488 youths (ages 7-17) with separation anxiety disorder, generalized anxiety disorder, and/or social phobia and their primary caregivers. Latent growth curve modeling assessed how pre-treatment parental trait anxiety symptoms predicted trajectories of youth anxiety symptom change across 12 weeks of treatment at four time points. Interactions between parental anxiety and treatment condition were tested. Parental anxiety was not associated with youth’s pre-treatment anxiety symptom severity. Controlling for parental trait anxiety, youth depressive symptoms, and youth age, youths who received COMB benefitted most. Counter to expectations, parental anxiety influenced youth anxiety symptom trajectory only within the SRT condition, whereas parental anxiety was not significantly associated with youth anxiety trajectories in the other treatment conditions. Specifically, within the SRT condition, higher levels of parental anxiety predicted a faster and greater reduction in youth anxiety over the acute treatment period compared to youths in the SRT condition whose parents had lower anxiety levels. While all active treatments produced favorable outcomes, results provide insight regarding the treatment-specific influence of parental anxiety on the time course of symptom change.

    Monitoring the neural activities from the ischemic penumbra provides critical information on neurological recovery after stroke. The purpose of this study is to evaluate the temporal alterations of neural activities using electroencephalography (EEG) from the acute phase to the chronic phase, and to compare EEG with the degree of post-stroke motor function recovery in a rat model of focal ischemic stroke. Male Sprague-Dawley rats were subjected to 90 min transient middle cerebral artery occlusion surgery followed by reperfusion for seven days (n = 58). The EEG signals were recorded at the pre-stroke phase (0 h), acute phase (3, 6 h), subacute phase (12, 24, 48, 72 h) and chronic phase (96, 120, 144, 168 h) (n = 8). This study analyzed post-stroke seizures and polymorphic delta activities (PDAs) and calculated quantitative EEG parameters such as the alpha-to-delta ratio (ADR). The ADR represented the ratio between alpha power and delta power, which indicated how fast the EEG activities were. Forelimb and hindlimb motor functions were measured by De Ryck's test and the beam walking test, respectively. In the acute phase, delta power increased fourfold with the occurrence of PDAs, and the histological staining showed that the infarct was limited to the striatum and secondary sensory cortex. In the subacute phase, the alpha power reduced to 50% of the baseline, and the infarct progressed to the forelimb cortical region. ADRs reduced from 0.23 ± 0.09 to 0.04 ± 0.01 at 3 h in the acute phase and gradually recovered to 0.22 ± 0.08 at 168 h in the chronic phase. In the comparison of correlations between the EEG parameters and the limb motor function from the acute phase to the chronic phase, ADRs were found to have the highest correlation coefficients with the beam walking test (r = 0.9524, p < 0.05) and De Ryck's test (r = 0.8077, p < 0.05). This study measured EEG activities after focal cerebral ischemia and showed that functional recovery was closely

    Anhedonia is one of the core symptoms of depression and has been linked to blunted responses to rewarding stimuli in striatal regions. Stress, a key vulnerability factor for depression, has been shown to induce anhedonic behavior, including reduced reward responsiveness in both animals and humans, but the brain processes associated with these effects remain largely unknown in humans. Emerging evidence suggests that stress has dissociable effects on distinct components of reward processing, as it has been found to potentiate motivation/‘wanting’ during the anticipatory phase but reduce reward responsiveness/‘liking’ during the consummatory phase. To examine the impact of stress on reward processing, we used a monetary incentive delay (MID) task and an acute stress manipulation (negative performance feedback) in conjunction with functional magnetic resonance imaging (fMRI). Fifteen healthy participants performed the MID task under no-stress and stress conditions. We hypothesized that stress would have dissociable effects on the anticipatory and consummatory phases in reward-related brain regions. Specifically, we expected reduced striatal responsiveness during reward consumption (mirroring patterns previously observed in clinical depression) and increased striatal activation during reward anticipation consistent with non-human findings. Supporting our hypotheses, significant Phase (Anticipation/Consumption) x Stress (Stress/No-stress) interactions emerged in the putamen, nucleus accumbens, caudate and amygdala. Post-hoc tests revealed that stress increased striatal and amygdalar activation during anticipation but decreased striatal activation during consumption. Importantly, stress-induced striatal blunting was similar to the profile observed in clinical depression under baseline (no-stress) conditions in prior studies. Given that stress is a pivotal vulnerability factor for depression, these results offer insight to better understand the etiology of this

    Serum amyloid A protein (SAA) surges 1,000-fold in the blood of acute-phase animals, and yet its function during these acute events remains unknown. We report herein that SAA stimulates a developmental program in cultured NRK-52E cells that culminates in differentiated and functional tubules that feature a proximal tubule phenotype. We also found strong SAA expression in states of tubule formation (in utero stage) and regeneration (recovery from ischemia-reperfusion injury). These data lend support to a novel view of a more localized renal acute-phase reaction, where renal SAA may act as a paracrine or autocrine molecule that promotes tubule formation during development and repair.

    It has been suggested that cognitive behaviour therapy (CBT) needs adaptation for it to be effective for patients from collectivistic cultures, as currently CBT is underpinned by individualistic values. In prior studies we have demonstrated that CBT could be adapted for Pakistani patients in Southampton, UK, and for local populations in Pakistan. Findings from these studies suggest that CBT can be adapted for patients from collectivistic cultures using a series of steps. In this paper we focus on these steps, and the process of adapting CBT for specific groups. The adaptation process should focus on three major areas of therapy, rather than simple translation of therapy manuals. These include (1) awareness of relevant cultural issues and preparation for therapy, (2) assessment and engagement, and (3) adjustments in therapy. We also discuss the best practice guidelines that evolved from this work to help therapists working with this population. We reiterate that CBT can be adapted effectively for patients from traditional cultures. This is, however, an emerging area in psychotherapy, and further work is required to refine the methodology and to test adapted CBT.

  17. Clinical disease activity and acute phase reactant levels are discordant among patients with active rheumatoid arthritis: acute phase reactant levels contribute separately to predicting outcome at one year

    PubMed Central

    2014-01-01

    Introduction Clinical trials of new treatments for rheumatoid arthritis (RA) typically require subjects to have an elevated acute phase reactant (APR), in addition to tender and swollen joints. However, despite the elevation of individual components of the Clinical Disease Activity Index (CDAI) (tender and swollen joint counts and patient and physician global assessment), some patients with active RA may have normal erythrocyte sedimentation rate (ESR) and/or C-reactive protein (CRP) levels and thus fail to meet entry criteria for clinical trials. We assessed the relationship between CDAI and APRs in the Consortium of Rheumatology Researchers of North America (CORRONA) registry by comparing baseline characteristics and one-year clinical outcomes of patients with active RA, grouped by baseline APR levels. Methods This was an observational study of 9,135 RA patients who had both ESR and CRP drawn and a visit at which CDAI was >2.8 (not in remission). Results Of 9,135 patients with active RA, 58% had neither elevated ESR nor CRP; only 16% had both elevated ESR and CRP and 26% had either ESR or CRP elevated. Among the 4,228 patients who had a one-year follow-up visit, both baseline and one-year follow-up modified Health Assessment Questionnaire (mHAQ) and CDAI scores were lowest for patients with active RA but with neither APR elevated; both mHAQ and CDAI scores increased sequentially with the increase in number of elevated APR levels at baseline. Each individual component of the CDAI followed the same trend, both at baseline and at one-year follow-up. The magnitude of improvement in both CDAI and mHAQ scores at one year was associated positively with the number of APRs elevated at baseline. Conclusions In a large United States registry of RA patients, APR levels often do not correlate with disease activity as measured by joint counts and global assessments. These data strongly suggest that it is appropriate to obtain both ESR and CRP from RA patients at the initial

    Background The diagnosis of Chagas disease is complex due to the dynamics of parasitemia in the clinical phases of the disease. The molecular tests have been considered promissory because they detect the parasite in all clinical phases. Trypanosoma cruzi presents significant genetic variability and is classified into six Discrete Typing Units TcI-TcVI (DTUs) with the emergence of foreseen genotypes within TcI as TcIDom and TcI Sylvatic. The objective of this study was to determine the operating characteristics of molecular tests (conventional and Real Time PCR) for the detection of T. cruzi DNA, parasitic loads and DTUs in a large cohort of Colombian patients from acute and chronic phases. Methodology/Principal Findings Samples were obtained from 708 patients in all clinical phases. Standard diagnosis (direct and serological tests) and molecular tests (conventional PCR and quantitative PCR) targeting the nuclear satellite DNA region. The genotyping was performed by PCR using the intergenic region of the mini-exon gene, the 24Sa, 18S and A10 regions. The operating capabilities showed that performance of qPCR was higher compared to cPCR. Likewise, the performance of qPCR was significantly higher in acute phase compared with chronic phase. The median parasitic loads detected were 4.69 and 1.33 parasite equivalents/mL for acute and chronic phases. The main DTU identified was TcI (74.2%). TcIDom genotype was significantly more frequent in chronic phase compared to acute phase (82.1% vs 16.6%). The median parasitic load for TcIDom was significantly higher compared with TcI Sylvatic in chronic phase (2.58 vs.0.75 parasite equivalents/ml). Conclusions/Significance The molecular tests are a precise tool to complement the standard diagnosis of Chagas disease, specifically in acute phase showing high discriminative power. However, it is necessary to improve the sensitivity of molecular tests in chronic phase. The frequency and parasitemia of TcIDom genotype in chronic

    The circadian timing system (CTS) provides internal and external temporal coordination of an animal's physiology and behavior. In mammals, the generation and coordination of these circadian rhythms is controlled by a neural pacemaker, the suprachiasmatic nucleus (SCN), located within the hypothalamus. The pacemaker is synchronized to the 24 hour day by time cures (zeitgebers) such as the light/dark cycle. When an animal is exposed to an environment without time cues, the circadian rhythms maintain internal temporal coordination, but exhibit a 'free-running' condition in which the period length is determined by the internal pacemaker. Maintenance of internal and external temporal coordination are critical for normal physiological and psychological function in human and non-human primates. Exposure to altered gravitational environments has been shown to affect the amplitude, mean, and timing of circadian rhythms in species ranging from unicellular organisms to man. However, it has not been determined whether altered gravitational fields have a direct effect on the neural pacemaker, or affect peripheral parameters. In previous studies, the ability of a stimulus to phase shift circadian rhythms was used to determine whether a stimulus has a direct effect on the neural pacemaker. The present experiment was performed in order to determine whether acute exposure to a hyperdynamic field could phase shift circadian rhythms.

    Although individuals with sickle cell anaemia (SCA) have elevated baseline inflammation and endothelial activation, the acute phase response to maximal exercise has not been evaluated among children with SCA. We measured the acute phase response to maximal exercise testing for soluble vascular cell adhesion molecule (sVCAM) as well as interleukin 6 (IL6), total white blood cell (WBC) count, C-reactive protein (CRP) and D-dimer in a cohort of children with SCA and matched controls at baseline, immediately after, and 30, 60 and 120 min following exercise. Despite higher baseline levels of all biomarkers except CRP, the acute phase response from baseline to immediately after exercise was significantly greater in subjects versus controls for CRP (2·1 vs. 0·2 mg/l, P = 0·02) and D-dimer (160 vs. 10 μg/l, P < 0·01) only. Similar between-group trends were observed over time for all biomarkers, including sVCAM, IL6, total WBC, CRP and D-dimer. Lower fitness, defined by peak oxygen consumption (VO2 ), was independently associated with greater acute phase responses to exercise for sVCAM. Our results suggest maximal exercise may not be associated with any greater escalation of endothelial activation or inflammation in SCA and provide preliminary biomarker evidence for the safety of brief, high-intensity physical exertion in children with SCA.

    Pneumococcal phase variation of 37 middle ear and 31 nasopharyngeal isolates obtained from children with acute otitis media was examined in the absence of intervening culture. The fraction of the opaque colonies was significantly higher in middle ear isolates than in nasopharyngeal isolates. The difference is probably the result of the pneumococci adapting to differential selective environments.

    The majority of "responders" to first-line cognitive-behavioural therapy (CBT) and pharmacological treatments for obsessive-compulsive disorder (OCD) are left with residual symptoms that are clinically relevant and disabling. Therefore, there is pressing need for widely accessible efficacious alternative and/or adjunctive treatments for OCD. Accumulating evidence suggests that physical exercise may be one such intervention in the mood and anxiety disorders broadly, although we are aware of only two positive small-scale pilot studies that have tested its clinical benefits in OCD. This pilot study aimed to test the feasibility and preliminary efficacy of adding a structured physical exercise programme to CBT for OCD. A standard CBT group was delivered concurrently with a 12-week customized exercise programme to 11 participants. The exercise regimen was individualized for each participant based on peak heart rate measured using an incremental maximal exercise test. Reports of exercise adherence across the 12-week regimen exceeded 80%. A paired-samples t-test indicated very large treatment effects in Yale-Brown Obsessive-Compulsive Scale scores from pre- to post-treatment in CBT group cohorts led by expert CBT OCD specialists (d = 2.55) and junior CBT clinician non-OCD specialists (d = 2.12). These treatment effects are very large and exceed effects typically observed with individual and group-based CBT for OCD based on leading meta-analytic reviews, as well as previously obtained treatment effects for CBT using the same recruitment protocol without exercise. As such, this pilot work demonstrates the feasibility and significant potential clinical utility of a 12-week aerobic exercise programme delivered in conjunction with CBT for OCD. PMID:25738234

  12. Involvement of activated leukocytes in the regulation of plasma levels of acute phase proteins in microgravity simulation experiments

    Larina, Olga; Bekker, Anna; Turin-Kuzmin, Alexey

    2016-07-01

    Earth-based studies of microgravity effects showed the induction of the mechanisms of acute phase reaction (APR). APR comprises the transition of stress-sensitive protein kinases of macrophages and other responsive cells into the active state and the phosphorylation of transcription factors which in turn stimulate the production of acute-phase reaction cytokines. Leukocyte activation is accompanied by the acceleration of the formation of oxygen radicals which can serve a functional indice of leukocyte cell state. The series of events at acute phase response result in selective changes in the synthesis of a number of secretory blood proteins (acute phase proteins, APPs) in liver cells thus contributing the recovery of homeostasis state in the organism. Earlier experiment with head-down tilt showed the increase in plasma concentrations of two cytokine mediators of acute phase response, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) being the outcome of the activation of producer cells, foremost, leukocytes. In experiment with 4-day dry immersion chemiluminescent (ChL) reply of the whole blood samples to a test stimulus were studied along with the measurements of plasma levels of APPs, namely, alpha1-antitrypsin (alpha1-AT), alpha1-acid glycoprotein (alpha1-AGP), alpha2-macroglobulin (alpha2-M), ceruloplasmin (Cer), haptoglobin (Hp), C3-complement component (C3), C-reactive protein (CRP). Eight individuals aged 21.2 ± 3.2 years were the test subjects in the investigation. Protein studies showed a noticeable increase in the mean plasma levels of all APPs measured in experiment thus producing the evidence of the activation of acute phase response mechanisms while individual patterns revealed variability during the immersion period. The overall trends were similar to these in the previous immersion series. The augment in the strength of signal in stimulated light emission tests was higher after 1- and 2-day of immersion exposure than before the

    2016-01-01

    Objective To assess whether the cognitive function in the acute stage evaluated by domain-specific neuropsychological assessments would be an independent predictor of functional outcome after stroke. Methods Forty patients underwent 4 domain-specific neuropsychological examinations about 3 weeks after the onset of stroke. The tests included the Boston Naming Test (BNT), the construction recall test (CRT), the construction praxis test (CPT), and the verbal fluency test (VFT). The Korean version of Modified Barthel Index (K-MBI) at 3 months and the modified Rankin Scale (mRS) at 6 months were investigated as functional outcome after stroke. Functional improvement was assessed using the change in K-MBI during the first 3 months and subjects were dichotomized into 'good status' and 'poor status' according to mRS at 6 months. The domain-specific cognitive function along with other possible predictors for functional outcome was examined using regression analysis. Results The z-score of CPT (p=0.044) and CRT (p<0.001) were independent predictors for functional improvement measured by the change in K-MBI during the first 3 months after stroke. The z-score of CPT (p=0.049) and CRT (p=0.048) were also independent predictors of functional status at post-stroke 6 months assessed by mRS. Conclusion Impairment in visuospatial construction and memory within one month after stroke can be an independent prognostic factor of functional outcome. Domain-specific neuropsychological assessments could be considered in patients with stroke in the acute phase to predict long-term functional outcome. PMID:27152270

    The prospectively assessed time course of changes in ventricular repolarization during acute myocardial infarction (AMI) is reported in 32 patients admitted 2.0 +/- 1.8 (SD) hours after AMI onset. The initial corrected QT interval (QTc) upon hospitalization was longer in the 14 patients developing ventricular tachycardia (VT) within the first 48 hours as compared to QTc in the eight patients with frequent ventricular premature beats (VPBs) and to QTc in the 10 patients with infrequent VPBs. By the fifth day after AMI onset, the QTc shortened significantly only in the VT group, suggesting a greater initial abnormality of repolarization in these patients. All 32 patients had coronary angiography, radionuclide ventriculography, and myocardial perfusion scintigraphy before hospital discharge. Significant discriminating factors related to early phase VT in AMI included initially longer QT and QTc intervals, faster heart rate, higher peak serum levels of creatine kinase, acute anterior infarction, angiographically documented proximal stenosis of the left anterior descending coronary artery, and scintigraphic evidence of hypoperfusion of the interventricular septum. Prior infarction, angina pectoris, hypertension, multivessel coronary artery disease, and depressed left ventricular ejection fraction did not provide discrimination among the three different ventricular arrhythmia AMI groups. Researchers conclude that (1) the QT interval is frequently prolonged early in AMI, (2) the initial transiently prolonged ventricular repolarization facilitates and predicts complex ventricular tachyarrhythmias within the first 48 hours of AMI, (3) jeopardized blood supply to the interventricular septum frequently coexists, and (4) therapeutic enhancement of rapid recovery of the ventricular repolarization process merits investigation for prevention of VT in AMI.

    We previously demonstrated vast expansion of hypoxic areas in the leukemic microenvironment and provided a rationale for using hypoxia-activated prodrugs. PR104 is a phosphate ester that is rapidly hydrolyzed in vivo to the corresponding alcohol PR-104A and further reduced to the amine and hydroxyl-amine nitrogen mustards that induce DNA cross-linking in hypoxic cells under low oxygen concentrations. In this phase I/II study, patients with relapsed/refractory acute myeloid leukemia (n=40) after 1 or 2 prior treatments or acute lymphoblastic leukemia (n=10) after any number of prior treatments received PR104; dose ranged from 1.1 to 4 g/m2. The most common treatment-related grade 3/4 adverse events were myelosuppression (anemia 62%, neutropenia 50%, thrombocytopenia 46%), febrile neutropenia (40%), infection (24%), and enterocolitis (14%). Ten of 31 patients with acute myeloid leukemia (32%) and 2 of 10 patients with acute lymphoblastic leukemia (20%) who received 3 g/m2 or 4 g/m2 had a response (complete response, n=1; complete response without platelet recovery, n=5; morphological leukemia-free state, n=6). The extent of hypoxia was evaluated by the hypoxia tracer pimonidazole administered prior to a bone marrow biopsy and by immunohistochemical assessments of hypoxia-inducible factor alpha and carbonic anhydrase IX. A high fraction of leukemic cells expressed these markers, and PR104 administration resulted in measurable decrease of the proportions of hypoxic cells. These findings indicate that hypoxia is a prevalent feature of the leukemic microenvironment and that targeting hypoxia with hypoxia-activated prodrugs warrants further evaluation in acute leukemia. The trial is registered at clinicaltrials.gov identifier: 01037556. PMID:25682597

    There is no consensus about the best time to start exercise after peripheral nerve injury. We evaluated the morphological and functional characteristics of the sciatic nerves of rats that began to swim immediately after crush nerve injury (CS1), those that began to swim 14 days after injury (CS14), injured rats not submitted to swimming (C), and uninjured rats submitted to swimming (S). After 30 days the number of axons in CS1 and CS14 was lower than in C (P < 0.01). The diameter of axons and nerve fibers was larger in CS1 (P < 0.01) and CS14 (P < 0.05) than in C, and myelin sheath thickness was lower in all crushed groups (P < 0.05). There was no functional difference between CS1 and CS14 (P > 0.05). Swimming exercise applied during the acute or late phase of nerve injury accelerated nerve regeneration and synaptic elimination after axonotmesis, suggesting that exercise may be initiated immediately after injury.

    Distemper disease is an infectious disease reported in several species of domestic and wild carnivores. The high mortality rate of animals infected with canine distemper virus (CDV) treated with currently available therapies has driven the study of new efficacious treatments. Mesenchymal stem cell (MSC)-based therapy is a promising therapeutic option for many degenerative, hereditary, and inflammatory diseases. Therefore, the aim of this study was to characterize stem cells derived from the canine fetal olfactory epithelium and to assess the systemic response of animals infected with CDV to symptomatic therapy and treatment with MSCs. Eight domestic mongrel dogs (N = 8) were divided into two groups: support group (SG) (N = 5) and support group + cell therapy (SGCT) (N = 3), which were monitored over 15 days. Blood samples were collected on days 0, 6, 9, 12, and 15 to assess blood count and serum biochemistry (urea, creatinine, alanine transferase, alkaline phosphatase, gamma-glutamyl transferase, total protein, albumin, and globulin), and urine samples were obtained on days 0 and 15 for urinary evaluation (urine I). The results showed a high mortality rate (SG = 4 and SGCT = 2), providing inadequate data on the clinical course of CDV infection. MSC therapy resulted in no significant improvement when administered during the acute phase of canine distemper disease, and a prevalence of animals with high mortality rate was found in both groups due to the severity of symptoms.

    Seventeen burned patients were investigated--Group I (n=10) with a mean burned area expressed as unit burn standard (UBS) of 69 +/- 24 and Group II (n = 7) with a mean UBS of 23 +/- 8. Blood samples were collected immediately after admission, 6-12 h after injury, during the morning and evening of day 1, and then daily for 2 weeks. This prospective study demonstrated complement activation in vivo in all burned patients, measured by C3d/C3 ratio index which was not related to the extent of the burned surface. A significant protease-antiprotease imbalance, correlated to the severity of burns, was found, leukocyte elastase was increased throughout the observation period, alpha 2-macroglobulin drastically decreased in severely burned patients, and alpha 1-proteinase inhibitor promptly decreased below the normal level in patients with more than 40 UBS. Finally, there was a delayed but then persistent acute-phase reactant protein response involving C-reactive protein, haptoglobin and alpha 1-acid glycoprotein, the concentrations of which reached a plateau on days 6 or 7.

  20. NRF2 and the Phase II Response in Acute Stress Resistance Induced by Dietary Restriction

    PubMed Central

    Hine, Christopher M.; Mitchell, James R.

    2013-01-01

    Dietary restriction (DR) as a means to increase longevity is well-established in a number of model organisms from yeast to primates. DR also improves metabolic fitness and increases resistance to acute oxidative, carcinogenic and toxicological stressors - benefits with more immediate potential for clinical translation than increased lifespan. While the detailed mechanism of DR action remains unclear, a conceptual framework involving an adaptive, or hormetic response to the stress of nutrient/energy deprivation has been proposed. A key prediction of the hormesis hypothesis of DR is that beneficial adaptations occur in response to an increase in reactive oxygen/nitrogen species (ROS). These ROS may be derived either from increased mitochondrial respiration or increased xenobiotic metabolism in the case of some DR mimetics. This review will focus on the potential role of the redox-sensing transcription factor NF-E2-related factor 2 (NRF2) and its control of the evolutionarily conserved antioxidant/redox cycling and detoxification systems, collectively known as the Phase II response, in the adaptive response to DR.

    2014-03-01

    We have previously shown that peripherally restricted acute phase response (APR) elicited by intraperitoneal (i.p.) injection of a viral mimic, polyinosinic-polycytidylic acid (PIC), renders the brain hypersusceptible to excitotoxic insult as seen from profoundly exacerbated kainic acid (KA)-induced seizures. In the present study, we found that this hypersusceptibility was protracted for up to 72 h. RT-PCR profiling of hippocampal gene expression revealed rapid upregulation of 23 genes encoding cytokines, chemokines and chemokine receptors generally within 6 h after PIC challenge. The expression of most of these genes decreased by 24 h. However, two chemokine genes, i.e., Ccl19 and Cxcl13 genes, as well as two chemokine receptor genes, Ccr1 and Ccr7, remained upregulated for 72 h suggesting their possible involvement in the induction and sustenance of seizure hypersusceptibility. Also, 12 genes encoding proteins related to glutamatergic and GABAergic neurotransmission featured initial upregulation or downregulation followed by gradual normalization. The upregulation of the Gabrr3 gene remained upregulated at 72 h, congruent with its plausible role in the hypersusceptible phenotype. Moreover, the expression of ten microRNAs (miRs) was rapidly affected by PIC challenge, but their levels generally exhibited oscillating profiles over the time course of seizure hypersusceptibility. These results indicate that protracted seizure susceptibility following peripheral APR is associated with a robust polygenic response in the hippocampus. PMID:24363211

    The distinction between exudates and transudates is very important in the patient management. Here we evaluate whether the acute-phase protein serum amyloid A (SAA), in comparison with C reactive protein (CRP) and total protein (TP), can be useful in this discrimination. CRP, SAA, and TP were determined in 36 exudate samples (27 pleural and 9 ascitic) and in 12 transudates (9 pleural and 3 ascitic). CRP, SAA, and TP were measured. SAA present in the exudate corresponded to 10% of the amount found in serum, that is, the exudate/serum ratio (E/S) was 0.10 ± 0.13. For comparison, the exudate/serum ratio for CRP and TP was 0.39 ± 0.37 and 0.68 ± 0.15, respectively. There was a strong positive correlation between serum and exudate SAA concentration (r = 0.764;p < 0.0001). The concentration of SAA in transudates was low and did not overlap with that found in exudates (0.02-0.21 versus 0.8–360.5 g/mL). SAA in pleural and ascitic exudates results mainly from leakage of the serum protein via the inflamed membrane. A comparison of the E/S ratio of SAA and CRP points SAA as a very good marker in discriminating between exudates and transudates. PMID:16864904

    There is no consensus about the best time to start exercise after peripheral nerve injury. We evaluated the morphological and functional characteristics of the sciatic nerves of rats that began to swim immediately after crush nerve injury (CS1), those that began to swim 14 days after injury (CS14), injured rats not submitted to swimming (C), and uninjured rats submitted to swimming (S). After 30 days the number of axons in CS1 and CS14 was lower than in C (P < 0.01). The diameter of axons and nerve fibers was larger in CS1 (P < 0.01) and CS14 (P < 0.05) than in C, and myelin sheath thickness was lower in all crushed groups (P < 0.05). There was no functional difference between CS1 and CS14 (P > 0.05). Swimming exercise applied during the acute or late phase of nerve injury accelerated nerve regeneration and synaptic elimination after axonotmesis, suggesting that exercise may be initiated immediately after injury.

    Distemper disease is an infectious disease reported in several species of domestic and wild carnivores. The high mortality rate of animals infected with canine distemper virus (CDV) treated with currently available therapies has driven the study of new efficacious treatments. Mesenchymal stem cell (MSC)-based therapy is a promising therapeutic option for many degenerative, hereditary, and inflammatory diseases. Therefore, the aim of this study was to characterize stem cells derived from the canine fetal olfactory epithelium and to assess the systemic response of animals infected with CDV to symptomatic therapy and treatment with MSCs. Eight domestic mongrel dogs (N = 8) were divided into two groups: support group (SG) (N = 5) and support group + cell therapy (SGCT) (N = 3), which were monitored over 15 days. Blood samples were collected on days 0, 6, 9, 12, and 15 to assess blood count and serum biochemistry (urea, creatinine, alanine transferase, alkaline phosphatase, gamma-glutamyl transferase, total protein, albumin, and globulin), and urine samples were obtained on days 0 and 15 for urinary evaluation (urine I). The results showed a high mortality rate (SG = 4 and SGCT = 2), providing inadequate data on the clinical course of CDV infection. MSC therapy resulted in no significant improvement when administered during the acute phase of canine distemper disease, and a prevalence of animals with high mortality rate was found in both groups due to the severity of symptoms.

    The aim of this study was to investigate the effects of transport-related stress on the liver gene expression of four acute phase proteins (APP), namely α1-acid glycoprotein (AGP), C-Reactive Protein (CRP), Serum Amyloid A (SAA) and PIT54, in turkeys (Meleagris gallopavo). A group of seven BUT BIG 6 commercial hens was subjected to a two-hour long road transportation and the quantitative gene expression of APP in the liver was compared to that of a non transported control group. The expression of AGP and CRP mRNA was found to be increased in animals slaughtered after road transport. The presence of AGP protein was also confirmed by immunohistochemistry and Western blotting. The results of this study showed that road-transport may induce the mRNA expression of immune related proteins. The finding that AGP and CRP can be upregulated during transport could suggest their use as for the assessment of turkey welfare during transport.

    We carried out estimations of the following acute phase proteins: C-reactive protein (CRP), alpha-1-antitrypsin (AAT), alpha-1-acid glycoprotein (AAG), alpha-2-ceruloplasmin (CER), and alpha-2-haptoglobin (HPT) in serum and in cerebrospinal fluid (CSF) in patients with bacterial meningitis (BM, n = 30) and viral meningitis (VM, n = 30). We have shown that determinations of concentrations of AAG and CRP in serum and CER in CSF are useful in differentiation between BM and VM. The diagnostic power of these three tests (the areas under their ROC curves equal 0.942, 0.929, and 0.931, respectively) is bigger, though statistically not significantly, than that of traditional parameters of BM in CSF, i.e., total protein concentration and white blood cell count. Determination of AAG, CRP, and AAT in serum is a valuable monitoring marker in the course of BM treatment. Convenience of serum sampling constitutes an advantage over traditional BM parameters in CSF. PMID:8521602

    Transport proteins, acute-phase reactant proteins (APRP), hematology, and anthropometry were studied in 34 sickle cell disease (SCD) children (20 boys, 14 girls) and 27 controls without growth deficits (13 boys, 14 girls) [corrected]. The age range was 1/2 to 16 1/2 years. Weight deficits (< 80%) by Waterlow's classification were observed in 41% of SCD boys and 25% of SCD girls, and height deficits (< 90%) were observed in 25% SCD boys and 25% girls. Mean white blood cell counts were significantly higher (P < .001) and hematocrit and hemoglobin (Hb) lower (P < .005) in SCD children than in controls. Although both groups had similar mean levels of albumin, transferrin, and APRP, SCD children had significantly lower mean levels of retinol-binding protein (RBP) (P < .001) and retinol-prealbumin (P < .001). Retinol-binding protein levels were abnormal in 18 (53%) SCD children and in only 23% controls (chi 2 = 14.06; P < 0.005); transferrin levels were abnormal in 20% of SCD children and in none of the controls. Children with SC and SF Hb phenotype had normal mean levels of RBP, whereas those with S beta thal and SS phenotype had levels below normal. Growth-retarded children by weight and height had reduced mean levels of RBP and prealbumin compared with growth-normal SCD children. The implication of primary protein-energy malnutrition on growth retardation in SCD children is under study. PMID:7512147

    During the adulticide treatment of Dirofilaria immitis the worms die releasing fragments of parasites and causing pulmonary thromboembolisms which could exacerbate the clinical condition. To determine the utility of acute phase proteins (APPs) to monitor the progression of the treatment, different positive [C-reactive protein (CRP), haptoglobin (hp)] and negative [albumin, paraoxonase-1(PON-1)] APPs were measured in 15 heartworm-infected dogs (5 with high and 10 with low parasite burden) following adulticide treatment. The results showed increased concentrations of CRP, decreased concentrations of haptoglobin and PON-1 in infected dogs before starting the treatment. Progressive but not significant increases were observed in PON-1 activity and albumin concentration along the treatment. After the treatment with doxycycline and ivermectine a decrease in CRP and Hp levels was experienced, which could reflect a reduction of the vascular inflammation caused by the elimination of Wolbachia and reduction of microfilariae. Fifteen days after the first melarsomine injection, marked increases in CRP and Hp were observed, which could be due to pulmonary inflammation and thromboembolism caused by the post-adulticide death of the worms. This increase was greater in dogs with high parasite burden. As the pathology disappeared, there was an improvement in the concentrations of CRP and Hp, returning into reference values in dogs with low parasite burden at the end of the treatment. The measurement of CRP and Hp could be a resource of support to evaluate the magnitude of the post-adulticide complications during the adulticide treatment of D. immitis. PMID:25801227

    Chronic viral hepatitis B (CHB) is an important cause of morbidity and mortality. Adipokine stimulation might play an important role in the pathogenesis of chronic inflammation. The aim of this study was to evaluate serum visfatin concentrations and the relationship between visfatin, fibrosis, liver inflammation, and acute phase reactants in CHB patients.The sampling universe of the study consisted of 41 CHB patients and 25 healthy controls. All patients had positive hepatitis B surface antigen (Hepatitis e antigen (HBeAg) positive n: 7, n: 34 HBeAg negative) for at least 6 months and detectable serum HBV DNA. Serum visfatin concentrations were significantly higher in the CHB patients [18.0 ± 10.9 ng dL(-1)] than in the healthy controls [9.4 ± 1.6 ng dL(-1)] [P < 0.001]. On the other hand, fibrinogen and haptoglobin concentrations were significantly lower in CHB patients. A strong negative correlation was observed between serum visfatin concentration, haptoglobin, and fibrinogen levels; however, there was no significant correlation between visfatin, glucose, alanine aminotransferase, aspartate aminotransferase, BMI, Knodell score, fibrosis score, hepatitis B virus DNA, sedimentation, and C-reactive protein. Visfatin concentrations were elevated and visfatin was negatively correlated with haptoglobin and fibrinogen levels in CHB patients.

    Inflammatory disease states (infection, arthritis) are associated with reduced drug oxidation by the cytochrome P450 3A system. Many chemotherapy agents are metabolised through this pathway, and disease may therefore influence inter-individual differences in drug pharmacokinetics. The purpose of this study was to assess cytochrome P450 3A function in patients with advanced cancer, and its relation to the acute-phase response. We evaluated hepatic cytochrome P450 3A function in 40 patients with advanced cancer using the erythromycin breath test. Both the traditional C20min measure and the recently proposed 1/TMAX values were estimated. The marker of acute-phase response, C-reactive protein and the pro-inflammatory cytokines IL-6, IL-1β, TNFα and IL-8 were measured in serum or plasma at baseline. Cancer patients with an acute phase response (C-reactive protein >10 mg l−1, n=26) had reduced metabolism as measured with the erythromycin breath test 1/TMAX (Kruskal–Wallis Anova, P=0.0062) as compared to controls (C-reactive protein ⩽10 mg l−1, n=14). Indeed, metabolism was significantly associated with C-reactive protein over the whole concentration range of this acute-phase marker (r=−0.64, Spearman Rank Correlation, P<0.00001). C-reactive protein serum levels were significantly correlated with those of IL-6 (Spearman coefficient=0.58, P<0.0003). The reduction in cytochrome P450 3A function with acute-phase reaction was independent of the tumour type and C-reactive protein elevation was associated with poor performance status. This indicates that the sub-group of cancer patients with significant acute-phase response have compromised drug metabolism, which may have implications for the safety of chemotherapy in this population.

    Despite negative outcomes for depressed mothers and their children, no treatment specifically designed to address maternal depression in the context of home visitation has emerged. In-Home Cognitive Behavioral Therapy (IH-CBT) is an adapted treatment that is delivered in the home, focuses on the needs of new mothers, and leverages ongoing home visiting to optimize engagement and outcomes. This study examined the efficacy of IH-CBT using a randomized clinical trial. Subjects were 93 new mothers in a home visiting program. Mothers with major depressive disorder identified at 3months postpartum were randomized into IH-CBT and ongoing home visitation (n=47) or standard home visitation (SHV; n=46) in which they received home visitation alone and could obtain treatment in the community. Depression was measured at pre- and posttreatment, and 3-month follow-up using interviews, clinician ratings, and self-report. Mothers receiving IH-CBT showed improvements in all indicators of depression relative to the SHV condition and these gains were maintained at follow-up. For example, 70.7% of mothers receiving IH-CBT were no longer depressed at posttreatment in terms of meeting criteria for major depressive disorder compared to 30.2% in the SHV group. These findings suggest that IH-CBT is an efficacious treatment for depressed mothers in home visitation programs.

  12. Rest energy expenditure is decreased during the acute as compared to the recovery phase of sepsis in newborns

    Background Little is known with respect to the metabolic response and the requirements of infected newborns. Moreover, the nutritional needs and particularly the energy metabolism of newborns with sepsis are controversial matter. In this investigation we aimed to evaluate the rest energy expenditure (REE) of newborns with bacterial sepsis during the acute and the recovery phases. Methods We studied nineteen neonates (27.3 ± 17.2 days old) with bacterial sepsis during the acute phase and recovery of their illness. REE was determined by indirect calorimetry and VO2 and VCO2 measured by gas chromatography. Results REE significantly increased from 49.4 ± 13.1 kcal/kg/day during the acute to 68.3 ± 10.9 kcal/kg/day during recovery phase of sepsis (P < 0.01). Similarly, VO2 (7.4 ± 1.9 vs 10 ± 1.5 ml/kg/min) and VCO2 (5.1 ± 1.7 vs 7.4 ± 1.5 ml/kg/min) were also increased during the course of the disease (P < 0.01). Conclusion REE was increased during recovery compared to the sepsis phase. REE of septic newborns should be calculated on individualized basis, bearing in mind their metabolic capabilities.

    Complex regional pain syndrome type 1 (CRPS1) may be evoked by ischemia/reperfusion, eliciting acute and chronic pain that is difficult to treat. Despite this, the underlying mechanism of CRPS1 has not been fully elucidated. Therefore, the goal of this study is to evaluate the involvement of inflammation, oxidative stress, and the transient receptor potential ankyrin 1 (TRPA1) channel, a chemosensor of inflammation and oxidative substances, in an animal model of chronic post-ischemia pain (CPIP). Male Wistar rats were subjected to 3 h hind paw ischemia/reperfusion (CPIP model). Different parameters of nociception, inflammation, ischemia, and oxidative stress were evaluated at 1 (acute) and 14 (chronic) days after CPIP. The effect of a TRPA1 antagonist and the TRPA1 immunoreactivity were also observed after CPIP. In the CPIP acute phase, we observed mechanical and cold allodynia; increased levels of tumor necrosis factor-α (hind paw), ischemia-modified albumin (IMA) (serum), protein carbonyl (hind paw and spinal cord), lactate (serum), and 4-hydroxy-2-nonenal (4-HNE, hind paw and spinal cord); and higher myeloperoxidase (MPO) and N-acetyl-β-D-glucosaminidase (NAGase) activities (hind paw). In the CPIP chronic phase, we detected mechanical and cold allodynia and increased levels of IMA (serum), protein carbonyl (hind paw and spinal cord), and 4-HNE (hind paw and spinal cord). TRPA1 antagonism reduced mechanical and cold allodynia 1 and 14 days after CPIP, but no change in TRPA1 immunoreactivity was observed. Different mechanisms underlie acute (inflammation and oxidative stress) and chronic (oxidative stress) phases of CPIP. TRPA1 activation may be relevant for CRPS1/CPIP-induced acute and chronic pain.

    Acute phase protein (APP) immunoassays and serum protein electrophoresis (SPEP) are assays for evaluating the inflammatory response and have use as diagnostic tools in a variety of species. Acute phase proteins are markers of inflammation that are highly conserved across different species while SPEP separates and quantifies serum protein fractions based on their physical properties. In the current study, serum samples from 35 clinically healthy Asian elephants (Elephas maximus) were analyzed using automated assays for C-reactive protein, serum amyloid A, and haptoglobin and SPEP. Robust methods were used to generate reference intervals for the APPs: C-reactive protein (1.3-12.8 mg/l), serum amyloid A (0-47.5 mg/l), and haptoglobin (0-1.10 mg/ml). In addition, SPEP was performed on these samples to establish reference intervals for each protein fraction. A combination of APPs and SPEP measurements are valuable adjunctive diagnostic tools in elephant health care.

    Renal and gastrointestinal pathologies are widespread in the captive cheetah (Acinonyx jubatus) population but are often diagnosed at a late stage, because diagnostic tools are limited to the evaluation of clinical signs or general blood examination. Presently, no data are available on serum proteins and acute-phase proteins in cheetahs during health or disease, although they might be important to improve health monitoring. This study aimed to quantify serum proteins by capillary electrophoresis in 80 serum samples from captive cheetahs, categorized according to health status and disease type. Moreover, serum amyloid A concentrations were measured via a turbidimetric immunoassay validated in domestic cats, whereas haptoglobin and C-reactive protein were determined by non-species-specific functional tests. Cheetahs classified as healthy had serum protein and acute phase protein concentrations within reference ranges for healthy domestic cats. In contrast, unhealthy cheetahs had higher (P < 0.001) serum amyloid A, alpha2-globulin, and haptoglobin concentrations compared with the healthy subgroup. Moreover, serum amyloid A (P = 0.020), alpha2-globulin (P < 0.001) and haptoglobin (P = 0.001) concentrations in cheetahs suffering from chronic kidney disease were significantly greater compared to the reportedly healthy cheetahs. Our study indicates that serum proteins in the cheetah can be analyzed by routine capillary electrophoresis, whereas acute-phase proteins can be measured using available immunoassays or non-species-specific techniques, which are also likely to be applicable in other exotic felids. Moreover, results suggest that serum amyloid A and haptoglobin are important acute-phase proteins in the diseased cheetah and highlight the need to evaluate their role as early-onset markers for disease.

    Background Particulate air pollution is associated with cardiovascular disease. Acute phase response is causally linked to cardiovascular disease. Here, we propose that particle-induced pulmonary acute phase response provides an underlying mechanism for particle-induced cardiovascular risk. Methods We analysed the mRNA expression of Serum Amyloid A (Saa3) in lung tissue from female C57BL/6J mice exposed to different particles including nanomaterials (carbon black and titanium dioxide nanoparticles, multi- and single walled carbon nanotubes), diesel exhaust particles and airborne dust collected at a biofuel plant. Mice were exposed to single or multiple doses of particles by inhalation or intratracheal instillation and pulmonary mRNA expression of Saa3 was determined at different time points of up to 4 weeks after exposure. Also hepatic mRNA expression of Saa3, SAA3 protein levels in broncheoalveolar lavage fluid and in plasma and high density lipoprotein levels in plasma were determined in mice exposed to multiwalled carbon nanotubes. Results Pulmonary exposure to particles strongly increased Saa3 mRNA levels in lung tissue and elevated SAA3 protein levels in broncheoalveolar lavage fluid and plasma, whereas hepatic Saa3 levels were much less affected. Pulmonary Saa3 expression correlated with the number of neutrophils in BAL across different dosing regimens, doses and time points. Conclusions Pulmonary acute phase response may constitute a direct link between particle inhalation and risk of cardiovascular disease. We propose that the particle-induced pulmonary acute phase response may predict risk for cardiovascular disease. PMID:23894396

    The expression of genes encoding the acute phase proteins (APP) during the course of Trypanasoma carassii infection in the goldfish was determined using quantitative PCR. Significant changes in the mRNA levels of ceruloplasmin (Cp), C-reactive protein (CRP), transferrin (Tf), hemopexin (Hx) and serum amyloid A (SAA) were observed in the kidney, liver and spleen at various days post infection (dpi). Of the five acute phase protein genes examined, CRP and SAA exhibited the highest expression in the tissues during the acute infection. Cp and Tf were up-regulated throughout the acute course of infection in the liver. During the chronic phase of the infection, APP expression in the liver was similar to that in the non-infected control fish. At 7 dpi, Cp, Tf and Hx were down-regulated in the spleen, and Cp and Tf kidney, but their mRNA levels gradually returned to those of control non-infected fish. In contrast, during the chronic phase of the infection, there was an up-regulation of Cp, Hx and Tf in the spleen, and Tf and SAA in the kidney. The goldfish CRP was cloned and functionally characterized. CRP was differentially expressed in normal goldfish immune cells, with highest expression in monocytes and lowest expression in mature macrophages. A recombinant goldfish CRP (rgfCRP) was generated using prokaryotic expression. rgfCRP enhanced complement-mediated killing of trypanosomes in vitro, and the lysis increased after addition of immune serum. rgfCRP did not affect the production of reactive oxygen and nitrogen intermediates by monocytes and macrophages, respectively.

    In Europe, Dengue Fever is one of the most frequent imported diseases and also autochthonous cases occurred in areas where the insect vector is present. Here, we describe a child returning from Philippines and diagnosed with Dengue Fever, through the information provided by parents about an ongoing outbreak in their municipality. An appropriate clinical management in the hospital was established to monitor the occurrence of complications and to cancel the risk of dengue virus transmission in the acute phase of infection.

    Our objective was to evaluate the effects of MP supply, through RUP supplementation, on the acute-phase response of beef steers following vaccination. On d 0, Brangus-crossbred steers (n = 24; 173 ± 31 kg; 175 ± 16 d of age) were randomly assigned to receive 1 of 3 isocaloric diets formulated to provide 85, 100, and 115% of the daily MP requirements of a beef steer gaining 0.66 kg of BW daily. Diets were limit-fed at 1.8% of BW (DM basis) and individually provided to steers once daily (0800 h) from d 0 to 29. Steers were weighed on d 0 and 29, following a 12-h period of feed and water withdrawal. On d 7, steers were vaccinated against Mannheimia haemolytica (OneShot, Pfizer), and blood samples were collected on d 0, 7, 8, 10, 14, 21, and 30. Plasma metabolites were analyzed as repeated measures using the MIXED procedure of SAS. Final BW and ADG were similar (P ≥ 0.50) among treatments (mean = 184 ± 9 kg and 0.5 ± 0.08 kg/d, respectively). Effects of time were detected (P < 0.01) for plasma concentrations of all acute-phase proteins, which peaked between d 7 to 14, returning to baseline concentrations by d 29. Treatment effects were not detected (P ≥ 0.19) for plasma concentrations of acid-soluble protein, albumin, fibrinogen, IGF-1 and serum amyloid-A. Plasma concentrations of total protein (TP) and plasma urea nitrogen (PUN) increased (P ≤ 0.05) with increasing supply of MP (87.1, 89.6, and 90.1 ± 1.09 mg TP/mL and 6.1, 8.3, and 10.3 ± 0.41 mg PUN/dL for 85, 100, and 115% MP steers, respectively). From d 10 to 29, steers provided 115% MP had less (P < 0.001) plasma concentrations of ceruloplasmin than steers fed 85 and 100% MP, which had similar plasma ceruloplasmin concentrations. On d 14, plasma concentrations of haptoglobin were greatest (P ≤ 0.06) for steers fed 115% MP, intermediate for 100% MP, and least for 85% MP (0.98, 0.71 and 0.44 ± 0.099 mg/mL, respectively). On d 10, plasma concentrations of creatinine were greater (P = 0.01) for steers

    To improve the activities of daily living of patients with injury to the central nervous system, physical therapy starting from the acute phase of the injury is important. Recently, the efficacy of physical therapy using a hybrid assistive limb (HAL) robot suit was reported. However, individual differences exist in the effects of HAL. We investigated factors predicting the effects of HAL in 15 patients at our institution with central nervous system injury, primarily due to stroke, who underwent training using HAL during the acute phase. Patients were classified as either “with HAL suitability” or “without HAL suitability” based on scores from 10-m walking speed, gait, satisfaction, and pain. In both groups, Brunnstrom stage before HAL intervention, Fugl-Meyer assessment (FMA), stroke impairment assessment set (SIAS), and functional independence measure (FIM) were evaluated. Although motor function items did not differ significantly, FIM cognitive function items (P = 0.036), visuospatial perception items on SIAS (P = 0.0277), and pain items on SIAS (P = 0.0122) differed significantly between groups. These results indicated that training using HAL does not involve pain in patients with central nervous system injury during the acute phase, and exhibits positive effects in patients without pain and with high communication ability and visuospatial perception function. When conducting HAL intervention, incorporating functional assessment scores (FIM and SIAS), including peripheral items, may be useful to predict the suitability of HAL. PMID:26538291

    The acute phase proteins LPS binding protein (LBP) and serum amyloid A (SAA) are produced by the liver and are present in the circulation. Both proteins have been shown to participate in the immune response to endotoxins. The intestinal mucosa forms a large surface that is continuously exposed to these microbial products. By secretion of antimicrobial and immunomodulating agents, the intestinal epithelium contributes to the defense against bacteria and their products. The aim of this study was to explore the influence of the inflammatory mediators TNF-alpha, IL-6, and IL-1beta on the release of LBP and SAA by intestinal epithelial cells (IEC). In addition, the induction of LBP and SAA release by cell lines of intestinal epithelial cells and hepatic cells was compared. The data obtained show that in addition to liver cells, IEC also expressed LBP mRNA and released bioactive LBP and SAA upon stimulation. Regulation of LBP and SAA release by IEC and hepatocytes was typical for class 1 acute phase proteins, although differences in regulation between the cell types were observed. Endotoxin did not induce LBP and SAA release. Glucocorticoids were demonstrated to strongly enhance the cytokine-induced release of LBP and SAA by IEC, corresponding to hepatocytes. The data from this study, which imply that human IEC can produce LBP and SAA, suggest a role for these proteins in the local defense mechanism of the gut to endotoxin. Furthermore, the results demonstrate that tissues other than the liver are involved in the acute phase response.

    Objective To determine whether baseline dimensions of adult insecure attachment (avoidant and anxious) moderated outcome in a secondary analysis of a randomized controlled trial comparing cognitive–behavioral therapy (CBT) plus supportive listening (CBT + SL) versus CBT plus interpersonal and emotional processing therapy (CBT + I/EP). Method Eighty-three participants diagnosed with generalized anxiety disorder (GAD) were recruited from the community and assigned randomly to CBT + SL (n = 40) or to CBT + I/EP (n = 43) within a study using an additive design. PhD-level psychologists treated participants. Blind assessors evaluated participants at pretreatment, posttreatment, 6-month, 12-month, and 2-year follow-up with a composite of self-report and assessor-rated GAD symptom measures (Penn State Worry Questionnaire, Hamilton Anxiety Rating Scale, Clinician’s Severity Rating). Avoidant and anxious attachment were assessed using self-reported dismissing and angry states of mind, respectively, on the Perceptions of Adult Attachment Questionnaire. Results Consistent with our prediction, at all assessments higher levels of dismissing styles in those who received CBT + I/EP predicted greater change in GAD symptoms compared with those who received CBT + SL for whom dismissiveness was unrelated to the change. At postassessment, higher angry attachment was associated with less change in GAD symptoms for those receiving CBT + I/EP, compared with CBT + SL, for whom anger was unrelated to change in GAD symptoms. Pretreatment attachment-related anger failed to moderate outcome at other time points and therefore, these moderation effects were more short-lived than the ones for dismissing attachment. Conclusions When compared with CBT + SL, CBT + I/EP may be better for individuals with GAD who have relatively higher dismissing styles of attachment. PMID:26052875

    The nervous and the immune systems share several molecules that control their development and function. We studied the temporal and spatial distribution of the immunoreactivity of two acute-phase cytokines, TNF-alpha and IL-1beta, in the developing sheep neocortex and compared it with the well-described distribution of fetuin, a fetal glycoprotein also known to modulate the production of cytokines by lipopolysaccharide (LPS)-stimulated monocytes and macrophages. TNF-alpha was present first at embryonic day 30 (E30) (term is 150 days in sheep) as a faint band of immunoreactivity between the ventricular zone and the primordial plexiform layer (preplate). IL-1beta was detected at the first appearance of the cortical plate (E35-E40). Both cytokines were present on both sides of the cortical plate, which contained fetuin-positive cells, but was free from cytokine staining. By E60, TNF-alpha immunoreactivity was less prominent than that of IL-1beta and was confined to the marginal zone and outer developing white matter; IL-1beta was present in the marginal zone and in two bands of immunoreactive cells, one at the border of the cortical plate/developing layer VI (cells of neuronal morphology) and the other at the border of layer V and the developing white matter (identified as microglia). By E80, TNF-alpha staining had disappeared and IL-1beta-immunopositive microglia were no longer detectable. By E100-E140 only a few immunoreactive cells were identified in layers V-VI; these did not co-localize with fetuin-positive cells. The differences in distribution between fetuin and the two cytokines suggest that the opsonizing role of fetuin, proposed for monocyte production of cytokines, is probably not present in the developing brain. However, early in neocortical development TNF-alpha and IL-1beta were present in the subplate zone at a time of intense synaptogenesis.

    Objective We tested nomothetic and idiographic convergence and change in three symptom measures during acute-phase cognitive therapy (CT) for depression and compared outcomes among patients showing different change patterns. Method Outpatients (N = 362; 69% women; 85% white; age mean = 43 years) with DSM-IV recurrent major depressive disorder completed the Hamilton Rating Scale for Depression (Hamilton, 1960), Beck Depression Inventory (Beck, Ward, Mendelson, Mock, & Erbaugh 1961), and Inventory for Depressive Symptomatology—Self-Report (Rush, Gullion, Basco, Jarrett, & Trivedi, 1996) on 14 occasions, and pre-/post-CT measures of social-interpersonal functioning and negative cognitive content. Results The three symptom measures marked the same severity and change constructs, and we offer improved formulas for inter-measure score conversions via their common factor. Pre-post CT symptom reductions were large (ds 1.71-1.92), and nomothetic symptom curves were log-linear (larger improvements earlier and smaller improvements later in CT). Nonetheless, only 30% of individual patients showed clear log-linear changes, whereas other patients showed linear (e.g., steady decreases; 20%), one-step (e.g., a quick drop; 16%), and unclassified (34%) patterns. Log-linear, linear, and one-step patients were generally similar to one another and superior to unclassified patients post-CT in symptom levels, response and stable remission rates, social-interpersonal functioning, and cognitive content (median d = 0.69). Conclusions Reaching a low-symptom “destination” at the end of CT via any coherent “path” is more important in the short-term than which path patients take. We discuss implications for theories of change, clinical monitoring of individuals’ progress in CT, and the need to investigate long-term outcomes of patients with differing symptom change patterns.

    The study was carried out in 89 men aged 21 to 57 years with a history of exposure to mercury vapour from 2 to 26 years during occupational work involving chlorine production by the method of mercury electrolysis. The workers were divided into three groups depending on the duration of occupational exposure: 1) 32 workers with a short history of exposure 2-10 years, 2) 37 workers with medium-long exposure - 11-20 years, and 3) 20 workers with a history of long exposure - 21-26 years. The urinary concentrations of mercury in these individuals was 73 +/- 60 microliters x 1(-1), and in blood this concentration was not exceeding 50 microliters x 1(-1). The control group comprised 40 men aged 17 to 52 years. They had not had any occupational exposure to chemicals, or harmful physical factors. On the basis of clinical, haematological and biochemical studies 89 workers with occupational exposure to mercury vapour were regarded as clinically healthy. None of them had any symptoms and signs of the complete neurasthenic syndrome or organic brain injury. Increased nervous excitability was the complaint of 24 workers, 9 had headaches, sleep disturbances were reported by 5, and a feeling of tiredness and apathy was mentioned by 5 men. EEG recording demonstrated 81 normal tracings, and moderately pathological records in 8 men. The parameters of immunity and proteins acute phase reaction were determined, measuring the concentration of immunoglobulins, lysozyme, C3c, C4, alpha 1-acid glycoprotein, haptoglobin and ceruloplasmin in serum.

    The Ross procedure of aortic valve replacement with a pulmonary autograft has several advantages in childhood over mechanical prostheses or homografts, especially in infectious endocarditis requiring early surgery. Between January 1997 and July 1998, 3 children with no known previous cardiac disease, aged 14 months, 10 and 11 years, had aortic valve infectious endocarditis. The causal organism was not identified in 1 case and the other two were due to staphylococcus aureus and corynebacterium diphteriae. All children had severe, rapidly progressive aortic regurgitation complicated by pulmonary oedema in the baby and systemic emboli in the two older children. Surgery was performed within 9 days, 1.5 month and 2 months after the onset of the disease. The postoperative course was uncomplicated in the 3 cases. Postoperative Doppler echocardiography showed absence of autograft dysfunction or stenosis, with the presence of pulmonary regurgitation in 1 case. Pulmonary autograft has the advantages of not requiring anticoagulation, of allowing growth of the aortic ring, of not being limited by the age of the patient and of having a low risk of degeneration and infectious endocarditis. Therefore, it seems particularly indicated for cases of complicated infectious endocarditis requiring early aortic valve replacement. The early (4.8%) and late (4.3%) mortality rates were comparable to those of other techniques and are lower than those associated with valve replacement with mechanical prostheses in cases of endocarditis (8.5% versus 40%). The secondary morbidity is 18.8% with dysfunction of the autograft and/or stenosis of the pulmonary homograft. Despite a limited follow-up, aortic valve replacement by a pulmonary homograft seems better than aortic valve replacement with a homograft or mechanical prosthesis, especially in cases of complicated infectious endocarditis requiring surgery in the acute phase. Further studies are required to confirm these encouraging results.

    2016-01-01

    Purpose Detecting sight-threatening retinopathy of prematurity (ROP) relies on a diagnostic examination (DE) performed by an experienced ophthalmologist. An alternative may be a telemedicine system where retinal images of at-risk infants are graded by readers to determine features of ROP indicating the need for a DE. Methods The multicenter “Telemedicine Approaches to Evaluating Acute-phase ROP” (e-ROP) Study is a cohort study of 2,000 infants with birth weights <1251g. At each visit, ophthalmologists perform DEs and non-physician imagers obtain iris and five retinal images with the disc positioned in the center, right, left, up anddown. Images are uploaded to a secure server for grading by non-physician readers for the detection of plus disease, stage 3 ROP and/or zone I disease, any of which indicates “referral-warranted ROP (RW-ROP).” Images from all infants with RW-ROP and a random sample of infants without RW-ROP (based on DEs) are selected for grading. Gradings are compared to DEs to determine the validity and evaluate reliability, feasibility, safety, and cost-effectiveness of the telemedicine system. Results e-ROP is conducted in 12 Clinical Centers in the US and Canada with Study Headquarters, the Data Coordinating Center and the Image Reading Center in Philadelphia and the ROP Data Center in Oklahoma City. 27 Study Center Coordinators, 34 ophthalmologists; 26 imagers, and 4 readers have been certified. All study data are submitted using a secure web-based system. Conclusion The design and findings of this study will be useful to conduct other ROP studies or evaluate telemedicine for other diseases.

    Background Epidemiologic and animal studies have shown that particulate air pollution is associated with increased risk of lung and cardiovascular diseases. Although the exact mechanisms by which particles induce cardiovascular diseases are not known, studies suggest involvement of systemic acute phase responses, including C-reactive protein (CRP) and serum amyloid A (SAA) in humans. In this study we test the hypothesis that diesel exhaust particles (DEP) – or carbon black (CB)-induced lung inflammation initiates an acute phase response in the liver. Results Mice were exposed to filtered air, 20 mg/m3 DEP or CB by inhalation for 90 minutes/day for four consecutive days; we have previously shown that these mice exhibit pulmonary inflammation (Saber AT, Bornholdt J, Dybdahl M, Sharma AK, Loft S, Vogel U, Wallin H. Tumor necrosis factor is not required for particle-induced genotoxicity and pulmonary inflammation., Arch. Toxicol. 79 (2005) 177–182). As a positive control for the induction of an acute phase response, mice were exposed to 12.5 mg/kg of lipopolysaccharide (LPS) intraperitoneally. Quantitative real time RT-PCR was used to examine the hepatic mRNA expression of acute phase proteins, serum amyloid P (Sap) (the murine homologue of Crp) and Saa1 and Saa3. While significant increases in the hepatic expression of Sap, Saa1 and Saa3 were observed in response to LPS, their levels did not change in response to DEP or CB. In a comprehensive search for markers of an acute phase response, we analyzed liver tissue from these mice using high density DNA microarrays. Globally, 28 genes were found to be significantly differentially expressed in response to DEP or CB. The mRNA expression of three of the genes (serine (or cysteine) proteinase inhibitor, clade A, member 3C, apolipoprotein E and transmembrane emp24 domain containing 3) responded to both exposures. However, these changes were very subtle and were not confirmed by real time RT-PCR. Conclusion Our findings

    Studies of hepatitis B virus (HBV) infection in non-human primates such as chimpanzees are no longer possible due to ethical considerations and the endangered status of chimpanzees since April 2007 in Japan. A human hepatocyte transplanted chimeric mouse was used to characterize HBV infectivity in serial stages of acute infection. Chimeric mice were inoculated intravenously with serum samples obtained from an experimentally infected chimpanzee with HBV. Sera from the pre-acute phases (i.e., rump-up viremia prior to anti-HBc) and late acute phases (i.e., declining phase of HBsAg and anti-HBcAb positive) were collected from the chimpanzees 57 and 244 days after inoculation. These sera contained 2.6 x 10(6) and 2.8 x 10(6) copies/ml of HBV DNA, respectively. Three chimeric mice inoculated intravenously with 100 microl of pre-acute serum (equivalent to 10(0) copy of HBV DNA) developed an HBV infection. The three chimeric mice that received 100 microl of pre-acute serum (equivalent to 10(1) copies of HBV DNA), developed high levels of serum HBV DNA. None of the three chimeric mice inoculated with 100 microl of 1:10(4) dilution (equivalent to 10(1) copies of HBV DNA) of late-acute serum was infected, while only one of three chimeric mice inoculated with 100 microl of 1:10(3) dilution (equivalent to 10(2) copies of HBV DNA) of late-acute serum developed an HBV infection. Based on these results, chimeric mice can be used as animal models for the study of HBV infectivity, pathogenesis and control. The results show that pre-acute phase HBV serum is about 100-times more infectious than late acute phase serum.

    Acute brain ischemia modifies synaptic plasticity by inducing ischemic long-term potentiation (iLTP) of synaptic transmission through the activation of N-Methyl-D-aspartate receptors (NMDAR). Thrombin, a blood coagulation factor, affects synaptic plasticity in an NMDAR dependent manner. Since its activity and concentration is increased in brain tissue upon acute stroke, we sought to clarify whether thrombin could mediate iLTP through the activation of its receptor Protease-Activated receptor 1 (PAR1). Extracellular recordings were obtained in CA1 region of hippocampal slices from C57BL/6 mice. In vitro ischemia was induced by acute (3 minutes) oxygen and glucose deprivation (OGD). A specific ex vivo enzymatic assay was employed to assess thrombin activity in hippocampal slices, while OGD-induced changes in prothrombin mRNA levels were assessed by (RT)qPCR. Upon OGD, thrombin activity increased in hippocampal slices. A robust potentiation of excitatory synaptic strength was detected, which occluded the ability to induce further LTP. Inhibition of either thrombin or its receptor PAR1 blocked iLTP and restored the physiological, stimulus induced LTP. Our study provides important insights on the early changes occurring at excitatory synapses after ischemia and indicates the thrombin/PAR1 pathway as a novel target for developing therapeutic strategies to restore synaptic function in the acute phase of ischemic stroke.

    Background The widespread use of smartphones makes effective therapies such as cognitive–behavioural therapy (CBT) potentially accessible to large numbers of people. Aims This paper reports the usage data of the first trial of Catch It, a new CBT smartphone app. Method Uptake and usage rates, fidelity of user responses to CBT principles, and impact on reported negative and positive moods were assessed. Results A relatively modest proportion of people chose to download the app. Once used, the app tended to be used more than once, and 84% of the user-generated content was consistent with the basic concepts of CBT. There were statistically significant reductions in negative mood intensity and increases in positive mood intensity. Conclusions Smartphone apps have potential beneficial effects in mental health through the application of basic CBT principles.

    Acute rheumatic fever (ARF) is associated with systemic inflammation and arterial stiffness during the acute stage. It has not been reported if arterial stiffness remains after recovery. The aim of this study was to determine the arterial stiffness during acute stage and 6 months after recovery from ARF. Arterial stiffness was assessed by carotid femoral pulse wave velocity (PWV) in 23 ARF patients during the acute stage of ARF and 6 months later. Simultaneously, erythrocyte sedimentation rate (ESR) and other anthropometric measurements were taken during both stages. There was a significant reduction in PWV; 6.5 (6.0, 7.45) m/s to 5.9 (5.38, 6.48) m/s, p=0.003 6 months after the acute stage of ARF. Similarly, ESR was also significantly reduced from 92.0 (37.5, 110.50) mm/hr to 7.0 (5.0, 16.0) mm/hr, p=0.001. In conclusion, arterial stiffness improved 6 months after the acute stage with routine aspirin treatment; this correlates well with the reduction in systemic inflammation. PMID:27130739

    Successful execution of intentions, but also the failure to recall are common phenomena in everyday life. The planning, retention, and realization of intentions are often framed as the scientific concept of prospective memory. The current study aimed to examine the influence of acute stress on key dimensions of complex "real life" prospective memory. To this end, we applied a prospective memory task that involved the planning, retention, and performance of intentions during a fictional holiday week. Forty healthy males participated in the study. Half of the subjects were stressed with the Socially Evaluated Cold Pressor Test (SECPT) before the planning of intentions, and the other half of the participants underwent a control procedure at the same time. Salivary cortisol was used to measure the effectiveness of the SECPT stress induction. Stressed participants did not differ from controls in planning accuracy. However, when we compared stressed participants with controls during prospective memory retrieval, we found statistically significant differences in PM across the performance phase. Participants treated with the SECPT procedure before the planning phase showed improved prospective memory retrieval over time, while performance of controls declined. Particularly, there was a significant difference between the stress and control group for the last two days of the holiday week. Interestingly, control participants showed significantly better performance for early than later learned items, which could be an indicator of a primacy effect. This differential effect of stress on performance was also found in time- and event-dependent prospective memory. Our results demonstrate for the first time, that acute stress induced before the planning phase may improve prospective memory over the time course of the performance phase in time- and event-dependent prospective memory. Our data thus indicate that prospective memory can be enhanced by acute stress. PMID:27370532

    Successful execution of intentions, but also the failure to recall are common phenomena in everyday life. The planning, retention, and realization of intentions are often framed as the scientific concept of prospective memory. The current study aimed to examine the influence of acute stress on key dimensions of complex "real life" prospective memory. To this end, we applied a prospective memory task that involved the planning, retention, and performance of intentions during a fictional holiday week. Forty healthy males participated in the study.

    Background. In recent years, plasma base deficit has been used as a marker to determine the status of tissue perfusion in trauma patients and also to predict the outcome of these patients. This study was performed to investigate the effect of plasma base deficit in predicting burn patient outcome. Methods. This prospective cohort study was performed from October 2009 to October 2010 in the acute phase of burn patients who were admitted within 6 h post-injury to Motahari Burn Hospital in Iran. The patients were divided into two groups based on the plasma base deficit in the first 24 h post-injury: group A, in which the mean plasma base deficit was less than or equal to -6 (more negative), and group B, in which the mean plasma base deficit greater than -6. Statistical analysis was performed using SPSS v.16 software. Results. Thirty-eight patients were enrolled in each group. The mean plasma base deficit in group A (-7.76 ± 2.18 mmol) was significantly less than that in group B (-1.19 ± 2.82) mmol (p < 0.05). Although there was no significant difference between the mean of fluid resuscitation and urine output in the first 24 h after injury between the two groups (p > 0.05) and despite removal of interfering factors, there were significant differences between the systemic inflammatory response syndrome and the multiple organ dysfunction syndrome score and the percentage of sepsis between the two groups (p < 0.05). The mortality rate in group A (63.2%) was significantly higher than that in group B (36.8%) (p > 0.05). Conclusion. The plasma base deficit can be used as a valuable marker in the resuscitation of burn patients, along with clinical criteria. Physiological indicators (burn percentage, age, and mucosal burns) are not sufficient to predict mortality and morbidity in burn patients, and it is necessary to investigate the role of biochemical markers such as base deficit in determining the final outcome of burn patients.

    A restricted schedule of food access promotes numerous metabolic and physiological adaptations to optimize the biochemical handling of nutrients. The restricted feeding activates responses in hypothalamic and midbrain areas, as well as in peripheral organs involved in energy metabolism. A restricted feeding schedule (RFS) is associated with marked behavioral arousal coincident with the food anticipatory activity (FAA) and extreme hyperphagia during food access. Food restriction is also accompanied by changes in an array of stress-related parameters, such as increase in corticosterone, slower rate in body weight gain, and reduction in retroperitoneal and epididymal adipose tissue. During RFS, the liver shows a diversity of biochemical and physiologically adaptations that are advantageous for food ingestion and processing, as well as for adequate nutrient distribution to other tissues. Taking into account the probable relationship between stressful conditions and the metabolic adaptations in the liver, we addressed whether an acute-phase response (APR), or a pro-inflammatory state, occurred after three weeks of 2 h food restriction. First, we compared the circulating levels of inflammation markers (interleukin-1alpha, interleukin-6, tumor necrosis factor-alpha), and APR proteins (C-reactive protein and fibrinogen) in rats under food restriction to those in rats treated with lipopolysacharide, a strong inducer of the APR. Second, the influence of RFS on the daily rhythms of systemic cytokines and APR proteins was characterized. Third, we tested if the feeding condition (22 h fasting and 2 h refeeding) influences these parameters. Finally, we assessed if a local stressed state was established in the liver associated with the restricted feeding by measuring the activation of the transcriptional factor NF-kappaB (nuclear factor kappa-light-chain-enhancer of activated B cells). The results showed that the following occurred during RFS: no APR was implemented; food

    Previous research indicates that early weaning before shipment can reduce transportation-induced increases in acute-phase proteins (APP) and can increase feedlot performance in beef calves. These data suggest that the combination of weaning and transport stress may compromise the immune system of calves, thus hindering subsequent performance and health. Therefore, our objective was to determine if the innate immune response of early weaned calves (EW; 80 d of age) differed from normal-weaned calves (NW; 250 d of age) in response to an endotoxin challenge. Eighteen Brahman x Angus calves (8 and 10 EW and NW, respectively; 233 +/- 5 kg of BW) were used. Calves were maintained on pasture with supplement and then moved into individual pens for 1 wk of acclimation before the start of the study. Calves were fitted with an indwelling jugular catheter 1 d before LPS challenge (0 h; 1.0 microg/kg of BW, intravenously). Blood samples were collected at 30-min intervals from -2 to 8 h. Serum samples were stored at -80 degrees C until analyzed for cortisol, tumor necrosis factor-alpha (TNF), IL-1 beta, IL-6, interferon-gamma (IFN), ceruloplasmin, and haptoglobin. Whereas LPS increased serum cortisol (P or= 0.15) was observed. A weaning age x time interaction (P

    Acute vascular injuries are the second most common cause of fatalities in patients with multiple traumatic injuries; thus, prompt identification and management is essential for patient survival. Over the past few years, multidetector CT (MDCT) using dual-phase scanning protocol has become the imaging modality of choice in high-energy deceleration traumas. The objective of this article was to review the role of dual-phase MDCT in the identification and management of acute vascular injuries, particularly in the chest and abdomen following multiple traumatic injuries. In addition, this article will provide examples of MDCT features of acute vascular injuries with correlative surgical and interventional findings.

    Acute phase proteins (APPs) are a group of circulating plasma proteins which undergo changes quantitatively or qualitatively at the time of inflammation. Many of these APPs are glycosylated, and it has been shown that alterations in glycosylation may occur in inflammatory and malignant conditions. Changes in glycosylation have been studied as potential biomarkers in cancer and also in chronic inflammatory conditions and have been shown to correlate with disease severity in certain conditions. Serine protease inhibitors (serpins), many of which are also APPs, are proteins involved in the control of proteases in numerous pathways. Alpha-1 Antitrypsin (AAT) is the most abundant serpin within the circulation and is an APP which has been shown to increase in response to inflammation. The primary role of AAT is maintaining the protease/antiprotease balance in the lung, but it also possesses important anti-inflammatory and immune-modulating properties. Several glycoforms of AAT exist, and they possess differing properties in regard to plasma half-life and stability. Glycosylation may also be important in determining the immune modulatory properties of AAT. The review will focus on the role and importance of glycosylation in acute phase proteins with particular attention to AAT and its use as a biomarker of disease. The review describes the processes involved in glycosylation, how glycosylation changes in differing disease states, and the alterations that occur to glycans of APPs with disease and inflammation. Finally, the review explores the importance of changes in glycosylation of AAT at times of inflammation and in malignant conditions and how this may impact upon the functions of AAT.

    Introduction Acute myocardial infarction is a social health problem of epidemiological relevance, with high levels of morbidity and mortality. Stress is one of the modifiable risk factors that triggers acute myocardial infarction. Stress is a result of a set of physiological reactions, which when exaggerated in intensity or duration can lead to imbalances in one's organism, resulting in vulnerability to diseases. Objective To identify the presence of stress and its phases in hospitalized and active labor market patients with unstable myocardial infarction and observe its correlation with the life of this population with stress. Methods The methodology used was a quantitative, descriptive and transversal research approach conducted with a total of 43 patients, who were still active in the labor market, presenting or not morbidities. Data collection occurred on the fourth day of their hospitalization and patients responded to Lipp's Stress Symptom Inventory for adults. Results Thirty-one patients (72.1%) presented stress and twelve (27.8%) did not. In patients with stress, the identified phases were: alert - one patient (3.2%); resistance -twenty-two patients (71.0%); quasi-exhaustion - six patients (19.4%) and exhaustion - two patients (6.5%). All women researched presented stress. Conclusion The results suggest a high level of stress, especially in the resistance phase, in the male infarcted population, hospitalized and active in the labor market. PMID:25859863

    From 129 patients with a recent stroke 105 survived and 24 died within 3 weeks from stroke-onset. At around 40 hours after the latter, the blood-levels of the acute-phase proteins ceruloplasmin and albumin did not forecast the death of the respective patients, but, in contradistinction, the level of fibrinogen was significantly higher in those who eventually died, than in those who survived. Therefore, a higher level of fibrinogen could be a risk-factor for death after stroke.

  7. Decreased expression of hepatocyte nuclear factor 3 alpha during the acute-phase response influences transthyretin gene transcription.

    Three distinct hepatocyte nuclear factor 3 (HNF-3) proteins (alpha, beta, and gamma) are known to regulate the transcription of numerous liver-specific genes. The HNF-3 proteins bind to DNA as monomers through a winged-helix motif, which is also utilized by a number of developmental regulators, including the Drosophila homeotic fork head (fkh) protein. We have previously characterized a strong-affinity HNF-3S site in the transthyretin (TTR) promoter region which is essential for expression in human hepatoma (HepG2) cells. In the current study, we identify an activating protein 1 (AP-1) site which partially overlaps the HNF-3S sequence in the TTR promoter. We show that in HepG2 cells the AP-1 sequence confers 12-O-tetradecanoylphorbol-13-acetate inducibility to the TTR promoter and contributes to normal TTR transcriptional activity. We also demonstrate that the HNF-3 proteins and AP-1 bind independently to the TTR AP-1-HNF-3 site, and cotransfection experiments suggest that they do not cooperate to activate an AP-1-HNF-3 reporter construct. In addition, 12-O-tetradecanoylphorbol-13-acetate exposure of HepG2 cells results in a reciprocal decrease in HNF-3 alpha and -3 gamma expression which may facilitate interaction of AP-1 with the TTR AP-1-HNF-3 site. In order to explore the role of HNF-3 in the liver, we have examined expression patterns of TTR and HNF-3 during the acute-phase response and liver regeneration. Partial hepatectomy produced minimal fluctuation in HNF-3 and TTR expression, suggesting that HNF-3 expression is not influenced by proliferative signals induced during liver regeneration. In acute-phase livers, we observed a dramatic reduction in HNF-3 alpha expression which correlates with a decrease in the expression of its target gene, the TTR gene. Furthermore, consistent with previous studies, the acute-phase livers are induced for c-jun but not c-fos expression. We propose that the reduction in TTR gene expression during the acute phase is likely due

    The objective herein was to estimate heterosis and breed effects in purebred and crossbred Romosinuano, Brahman, and Angus calves on acute phase protein response to weaning and transportation. Calves (n = 1,032) were weaned in September of 2002, 2003, and 2004 at approximately 7 mo of age. Approximately 28 d after weaning, steer calves (n = 482) were transported 1,800 km (20 h) to Oklahoma. Concentrations of 3 acute phase proteins (ceruloplasmin, fibrinogen, and haptoglobin) were measured in blood samples. Calves (steers and heifers) were sampled at weaning, and 24 and 72 h postweaning. For separate analyses, steers sent to Oklahoma were sampled before shipment, upon arrival, and 24 and 72 h after arrival. Combinations of the following fixed effects were investigated: sire breed, dam breed, sampling time, birth location, calf sex (weaning only), year, cow age, and interactions. Effects of special interest were sire breed x dam breed as an indication of breed group of calf, and the interaction of sire and dam breeds with sampling time. Weaning age and BW were investigated as linear and quadratic covariates. Sire of calf within sire breed was a random term. The correlation structure of repeated measures was determined by comparison of information criterion values for different structures within each analysis. In general, plasma acute phase protein concentrations in weaned calves increased with sampling time. Concentrations in the transported steers increased through sampling at 24 h after arrival, and were lower at 72 h. Significant estimates of heterosis were detected for Brahman-Angus haptoglobin concentrations at weaning (0.38 +/- 0.14 mg/dL x 100; 44%), and for Romosinuano-Angus fibrinogen concentrations at weaning (11.4 +/- 5.5 mg/dL; 10%) and in transported steers (22.5 +/- 8.4 mg/dL; 20%). The direct effect of Romosinuano was to increase (P <0.004) ceruloplasmin concentrations of weaned calves (4.1 +/- 0.9 mg/dL) and of transported steers (3.9 +/- 1.3 mg

    Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis has been suggested as a model for acute pancreatitis (AP), which allows evaluation of early alterations in the time course of the disease. The influence of the clinical course on procalcitonin (PCT), serum amyloid A (SAA), and several proinflammatory and inhibitory cytokines was evaluated in patients with AP following ERCP. Blood samples were prospectively collected from patients undergoing ERCP. The incidence of ERCP-induced pancreatic damage, defined as abdominal complaints, a threefold increase of serum lipase, and elevation of CRP from <10 to >20 mg/liter was 12.8% (12/94). Only mild clinical courses of acute pancreatitis were observed. PCT significantly increased in subjects with post-ERCP pancreatitis after 24 hr. However, PCT levels did not exceed 0.5 ng/ml in any patient. Interleukin-1 receptor antagonist (IL-1RA) began to differ from baseline 2 hr after ERCP, followed by interleukin-6 (IL-6, 6 hr), solubilized tumor necrosis factor-alpha receptor II (sTNF-alphaRII, 24 hr) and SAA (24 hr). Interleukin 10 (IL-10) showed marked interindividual variations with no obvious peak. Among all parameters evaluated, only peak values of IL-6 and IL-10 showed significant correlations with the reported pain score (r2 = 0.62/0.78), degree of ampullar irritation (r2 = NS/0.87), and the duration of ERCP (r2 = 0.58/0.76). No correlation was found with the volume of the injected contrast agent. We conclude that IL-10 and IL-6 appear to be useful to monitor patients after ERCP. The absence of any PCT elevation in the present study is in accordance with the clinical course of the patients who suffered from mild pancreatic damage without systemic or infectious complications.

    Examining the dynamics of stroke ischemia is limited by the standard use of 2D-volume or voxel-based analysis techniques. Recently developed spatiotemporal models such as the 4D metamorphosis model showed promise for capturing ischemia dynamics. We used a 4D metamorphosis model to evaluate acute ischemic stroke lesion morphology from the acute diffusion-weighted imaging (DWI) to final T2-weighted imaging (T2-w). In 20 representative patients, we metamorphosed the acute lesion to subacute lesion to final infarct. From the DWI lesion deformation maps we identified dynamic lesion areas and examined their association with perfusion values inside and around the lesion edges, blinded to reperfusion status. We then tested the model in ten independent patients from the STroke Imaging Repository (STIR). Perfusion values varied widely between and within patients, and were similar in contracting and expanding DWI areas in many patients in both datasets. In 25% of patients, the perfusion values were higher in DWI-contracting than DWI-expanding areas. A similar wide range of perfusion values and ongoing expansion and contraction of the DWI lesion were seen subacutely. There was more DWI contraction and less expansion in patients who received thrombolysis, although with widely ranging perfusion values that did not differ. 4D metamorphosis modeling shows promise as a method to improve use of multimodal imaging to understand the evolution of acute ischemic tissue towards its fate.

    PubMed Central

    2012-01-01

    Objective Sulfur mustard (SM) is one of the major potent chemical warfare and attractive weapons for terrorists. It has caused deaths to hundreds of thousands of victims in World War I and more recently during the Iran-Iraq war (1980–1988). It has ability to develop severe acute and chronic damage to the respiratory tract, eyes and skin. Understanding the acute and chronic biologic consequences of SM exposure may be quite essential for developing efficient prophylactic/therapeutic measures. One of the systems majorly affected by SM is the respiratory tract that numerous clinical studies have detailed processes of injury, diagnosis and treatments of lung. The low mortality rate has been contributed to high prevalence of victims and high lifetime morbidity burden. However, there are no curative modalities available in such patients. In this review, we collected and discussed the related articles on the preventive and therapeutic approaches to SM-induced respiratory injury and summarized what is currently known about the management and therapeutic strategies of acute and long-term consequences of SM lung injuries. Method This review was done by reviewing all papers found by searching following key words sulfur mustard; lung; chronic; acute; COPD; treatment. Results Mustard lung has an ongoing pathological process and is active disorder even years after exposure to SM. Different drug classes have been studied, nevertheless there are no curative modalities for mustard lung. Conclusion Complementary studies on one hand regarding pharmacokinetic of drugs and molecular investigations are mandatory to obtain more effective treatments. PMID:23351279

Thirty infected water buffaloes and 20 parasitologically free were used. In the present study there was significant (P ≤ 0.05) increase in haptoglobin (Hp), serum amyloid A (SAA), ceruloplasmin, α1-acid glycoprotein (AGP) and fibrinogen levels (2.18 ± 0.29 g/l, 156.58 ± 3.48 mg/l, 31.23 ± 1.25mg/dl, 370.23 ± 33.21 mg/l and 16.17 ± 1.18 g/l, respectively) in T. annulata infected water buffaloes when compared to healthy ones (0.13 ± 0.01 g/l, 23.9 ± 0.56 mg/l, 21.23 ± 1.21 mg/dl, 240.53 ± 22.45 mg/l and 4.2 ± 0.1 6g/l, respectively). Moreover, there was significant (P ≤ 0.05) increase in the levels of TNF-α, IL-1α, IL-6, IL-12, IL-1β and IFN-γ (2.55 ± 0.12 ng/ml, 98.32 ± 4.21 pg/ml, 152.32 ± 5.62 pg/ml, 26.44 ± 1.43 ng/ml, 240.33 ± 20.45 pg/ml and 123.65 ± 5.67 pg/ml, respectively) in T. annulata infected water buffaloes when compared to healthy ones (0.42 ± 0.04 ng/ml, 55.32 ± 3.21 pg/ml, 88.23 ± 3.21 pg/ml, 7.45 ± 0.67 ng/ml, 98.33 ± 3.45 pg/ml and 34.76 ± 1.56 pg/ml, respectively). There was also significant decrease (P ≤ 0.05) in the Hb content, PCV%, RBCs and WBCs counts in the diseased water buffaloes compared to the control ones. Neutropenia, eosinopenia, lymphopenia, monocytopenia and thrombocytopenia were also recorded. The biochemical changes revealed significant (P ≤ 0.05) elevation in the levels of AST, ALT, ALP, LDL-c, VLDL-c, BHBA and NEFA, with significant (P ≤ 0.05) decrease in the levels of total proteins, albumin, globulins, cholesterol, triglyceride, glucose, G6PD, calcium and phosphorus in T. annulata infected water buffaloes when compared to healthy ones. It could be concluded that APPs and pro-inflammatory cytokines could be used as a valuable biomarkers in T. annulata infected water buffaloes (Bubalus bubalis).

    Background: Intravenous alteplase (rt-PA) remains the only approved treatment for acute ischemic stroke, but its use remains limited. In a previous pilot dose-escalation study, intravenous tenecteplase showed promise as a potentially safer alternative. Therefore, a Phase IIB clinical trial was begun to a) choose a best dose of tenecteplase to carry forward, and b) to provide evidence for either promise or futility of further testing of tenecteplase versus rt-PA. If promise was established, then the trial would continue as a Phase III efficacy trial comparing the selected tenecteplase dose to standard rt-PA. Methods: The trial began as a small, multi-center, randomized, double-blind, controlled clinical trial comparing 0.1, 0.25, and 0.4 mg/kg tenecteplase with standard 0.9 mg/kg rt-PA in patients with acute stroke within 3 hours of onset. An adaptive sequential design used an early (24 hour) assessment of major neurological improvement balanced against occurrence of symptomatic intracranial hemorrhage (ICH) to choose a “best” dose of tenecteplase to carry forward. Once a “best” dose was established, the trial was to continue until at least 100 pairs of the selected tenecteplase dose versus standard rt-PA could be compared by 3 month outcome using the modified Rankin Scale in an interim analysis. Decision rules were devised to yield a clear recommendation to either stop for futility or to continue into Phase III. Results: The trial was prematurely terminated for slow enrollment after only 112 patients had been randomized at 8 clinical centers between 2006 and 2008. The 0.4 mg/kg dose was discarded as inferior after only 73 patients were randomized, but the selection procedure was still unable to distinguish between 0.1 mg/kg and 0.25 mg/kg as a propitious dose at the time the trial was stopped. There were no statistically persuasive differences in 3 month outcomes between the remaining tenecteplase groups and rt-PA. Symptomatic ICH rates were highest in the

    Cognitive behavioural therapy (CBT) is a well-established treatment for obsessive-compulsive disorder (OCD). However, few patients receive CBT, due to factors such as geographic limitations, perceived stigmatization, and lack of CBT services. Technology-delivered cognitive behavioural therapy (T-CBT) could be an effective strategy to improve patients' access to CBT. To date, a meta-analysis on the effectiveness of T-CBT for OCD has not been conducted. This study used meta-analytic techniques to summarize evidence on the efficacy of T-CBT for OCD versus control conditions and therapist-administered CBT. A meta-analysis according to Prisma guidelines was conducted on randomized controlled trials (RCTs) of T-CBT for OCD. Treatment was classified as T-CBT if evidence-based CBT active ingredients for OCD were included (psychoeducation, ERP, and cognitive restructuring), delivered through health technologies (e.g. self-help books, leaflets, and other forms of bibliotherapy) or remote communication technologies (e.g. the Internet, web-cameras, telephones, telephone-interactive voice response systems, and CD-ROMS). Studies using validated outcomes for OCD or depression were included. Eight trials were included (N = 420). Two trials were classified as at high risk of bias. T-CBT seemed to be superior to control conditions on OCD symptom outcomes at post-treatment (d = 0.82, 99% CI = 0.55-1.08, p = 0.001), but not on comorbid depression (d = 0.33, 99% CI = - 0.01-0.67, p = 0.020). Difference in the efficacy on OCD symptoms between T-CBT and therapist-administered CBT was not significant, despite a trend favouring therapist-administered CBT emerged (d = 0.45, 95% CI = 0.03-0.87, p = 0.033). Directions for research are discussed. Further RCTs are warranted to examine the efficacy of T-CBT for OCD.

    Child maltreatment contributes to depression in adults. Evidence indicates that such experiences are associated with poorer outcomes in treatment. Mothers in home visiting programs display high rates of depression and child maltreatment histories. In-Home Cognitive Behavioral Therapy (IH-CBT) was developed to treat maternal depression in home visiting. The purpose of this study was to examine the moderating effects of child maltreatment history on depression, social functioning, and parenting in mothers participating in a clinical trial of IH-CBT. Ninety-three depressed mothers in home visiting between 2 and 10 months postpartum were randomly assigned to IH-CBT (n = 47) plus home visiting or standard home visiting (SHV; n = 46). Mothers were identified via screening and then confirmation of major depressive disorder diagnosis. Measures of child maltreatment history, depression, social functioning, and parenting were administered at pre-treatment, post-treatment, and 3-month follow-up. Results indicated high rates of maltreatment in both conditions relative to the general population. Mixed model analyses found a number of main effects in which experiences of different types of trauma were associated with poorer functioning regardless of treatment condition. Evidence of a moderating effect of maltreatment on treatment outcomes was found for physical abuse and parenting and emotional abuse and social network size. Future research should focus on increasing the effectiveness of IH-CBT with depressed mothers who have experienced child maltreatment.

    Insomnia is a common feature among individuals with anxiety disorders. Studies of cognitive behavioral therapy (CBT) for anxiety report moderate effects on concomitant insomnia symptoms, but further research is still needed especially toward understanding how CBT for anxiety renders beneficial effects on insomnia. The current study examined changes in insomnia symptoms reported by 51 Veterans who participated in a group-based transdiagnostic CBT for anxiety intervention. In addition, insomnia symptoms were examined in relation to symptoms of general distress (GD), anhedonic depression (AD), and anxious arousal (AA) pre- to post-treatment. Results revealed a small, though statistically significant (p < .05) beneficial effect on insomnia symptoms. When changes in GD, AD, and AA were simultaneously examined in relation to changes in insomnia, change in AA was the only significant predictor of insomnia symptoms. The current study highlights the role of AA in the relationship between anxiety disorders and insomnia and demonstrates that reductions in insomnia during transdiagnostic CBT for anxiety can be largely attributed to changes in AA.

    The aim of this study was to evaluate the acute phase response of dairy cows to repeated liver biopsy in order to estimate the safety of this procedure during the transition period. Liver biopsies (up to 1000 mg of liver tissue) were conducted twice a day, 7 days before expected parturition and 3 days after calving. The number of needle insertions for each biopsy was recorded and was dependent on the amount of obtained tissue. Blood samples were taken on day 7 before expected parturition, then on days 3, 4, 7 and 14 after calving. Body temperature was measured daily in all 30 cows from day 3 until day 14 after calving. The concentrations of haptoglobin, serum amyloid A, fibrinogen and interleukin-6 were determined in serum and plasma. In 16.7% of cows, the rectal body temperature rose by ≥ 0.5°C on the day after liver biopsy. Although the concentrations of haptoglobin, serum amyloid A and fibrinogen increased significantly after calving (p<0.01), there was no influence of the number of biopsies on the acute phase reaction and repeated biopsy during the transition period had no effect on body temperature. Therefore, the procedure may be regarded as safe for cows during the transition period. PMID:27487515

    Abstract The consequences of mild traumatic brain injury (TBI) on neuronal functionality are only now being elucidated. We have now examined the changes in sensory encoding in the whisker-recipient barrel cortex and the brain tissue damage in the acute phase (24 h) after induction of TBI (n=9), with sham controls receiving surgery only (n=5). Injury was induced using the lateral fluid percussion injury method, which causes a mixture of focal and diffuse brain injury. Both population and single cell neuronal responses evoked by both simple and complex whisker stimuli revealed a suppression of activity that decreased with distance from the locus of injury both within a hemisphere and across hemispheres, with a greater extent of hypoactivity in ipsilateral barrel cortex compared with contralateral cortex. This was coupled with an increase in spontaneous output in Layer 5a, but only ipsilateral to the injury site. There was also disruption of axonal integrity in various regions in the ipsilateral but not contralateral hemisphere. These results complement our previous findings after mild diffuse-only TBI induced by the weight-drop impact acceleration method where, in the same acute post-injury phase, we found a similar depth-dependent hypoactivity in sensory cortex. This suggests a common sequelae of events in both diffuse TBI and mixed focal/diffuse TBI in the immediate post-injury period that then evolve over time to produce different long-term functional outcomes.

    Purpose The purpose of the study was to differentiate ischemic central retinal vein occlusion (CRVO) from nonischemic CRVO during the early acute phase using plasma homocysteine as a biochemical marker. Methods Fasting plasma homocysteine, serum vitamin B12, and folate levels were measured in 108 consecutive unilateral elderly adult (age >50 years) ischemic CRVO patients in the absence of local and systemic disease and compared with a total of 144 age and sex matched nonischemic CRVO patients and 120 age and sex matched healthy control subjects. Results Homocysteine level was significantly increased in the patients with ischemic CRVO in comparison with nonischemic CRVO patients (p = 0.009) and also in comparison with control subjects (p < 0.001). Analysis also showed that hyperhomocysteinemia was associated with increased incidence of ischemic CRVO (odds ratio, 18) than that for nonischemic CRVO (odds ratio, 4.5). Serum vitamin B12 and folate levels were significantly lower (p < 0.001) in CRVO patients compared to the control but were not significantly different between nonischemic and ischemic CRVO patients (p > 0.1). Conclusions Hyperhomocysteinemia can be regarded as useful in differentiating nonischemic and ischemic CRVO during the early acute phase in absence of local and systemic disease in the elderly adult (age >50 years) population.

    Treatment of solid tumors by photodynamic therapy (PDT) was recently shown to trigger a strong acute phase response. Using the mouse Lewis lung carcinoma (LLC) model, the present study examined complement and pentraxin proteins as PDT-induced acute phase reactants. The results show a distinct pattern of changes in the expression of genes encoding these proteins in the tumor, as well as host liver and spleen, following PDT mediated by photosensitizer Photofrin™. These changes were influenced by glucocorticoid hormones, as evidenced by transcriptional activation of glucocorticoid receptor and the upregulation of gene encoding this receptor. The expression of gene for glucocorticoid-induced zipper (GILZ) protein, whose activity is particularly susceptible to glucocorticoid regulation, was also changed in PDT-treated tumors. A direct demonstration that tumor PDT induces glucocorticoid hormone upregulation is provided by documenting elevated levels of serum corticosterone in mice bearing PDT-treated LLC tumors. Tumor response to PDT was negatively affected by blocking glucocorticoid receptor activity, which suggests that glucocorticoid hormones have a positive impact on the therapeutic outcome with this therapy.

    In the present study acute phase proteins (APPs) responses in pigs after subclinical infection with H1N1 swine influenza virus (SwH1N1) were evaluated. Fourteen 5 weeks old, seronegative piglets, both sexes were used. Ten of them were infected intranasally with SwH1N1. C-reactive protein (CRP), haptoglobin (Hp), serum amyloid A (SAA) and pig major acute phase protein (Pig-MAP) concentrations in serum were measured using commercial ELISAs. No significant clinical signs were observed in any of the infected pigs, however, all infected animals developed specific antibodies against SwH1N1 and viral shedding was observed from 2 to 5 dpi. Only concentrations of Hp and SAA were significantly induced after infection, with mean maximum levels from days 1 to 2 post infection (dpi). The concentrations of CRP and Pig-MAP remained generally unchanged, however in half of infected pigs the concentration of CRP tended to increase at 1 dpi (but without statistical significance). The results of our study confirmed that monitoring of APPs may be useful for detection of subclinically infected pigs. The use of SAA or Hp and Pig-MAP may be a valuable in combination [i.e. Hp (increased concentration) and Pig-MAP (unchanged concentration)] to detect subclinically SIV infected pigs, or to identify pigs actually producing a large amount of virus. Additional studies need to be done in order to confirm these findings.

    The synthesis and characterization of latex-protein complexes (LPC), from the acute phase recombinant antigen P35 (P35Ag) of Toxoplasma gondii and "core-shell" carboxylated or polystyrene (PS) latexes (of different sizes and charge densities) are considered, with the aim of producing immunoagglutination reagents able to detect recently acquired toxoplasmosis. Physical adsorption (PA) and chemical coupling (CC) of P35Ag onto latex particles at different pH were investigated. Greater amounts of adsorbed protein were obtained on PS latexes than on carboxylated latexes, indicating that hydrophobic forces govern the interactions between the protein and the particle surface. In the CC experiments, the highest amount of bound protein was obtained at pH 6, near the isoelectric point of the protein (IP=6.27). At this pH, it decreased both the repulsion between particle surface and protein, and the repulsion between neighboring molecules. The LPC were characterized and the antigenicity of the P35Ag protein coupled on the particles surface was evaluated by Enzyme-Linked ImmunoSorbent Assay (ELISA). Results from ELISA showed that the P35Ag coupled to the latex particles surface was not affected during the particles sensitization by PA and CC and the produced LPC were able to recognize specific anti-P35Ag antibodies present in the acute phase of the disease.

    Potentially harmful stimulation of the neuroendocrine axis occurs in the early hours of myocardial infarction. It has been suggested that this acute neuroendocrine response might be attenuated by early therapeutic reperfusion. To test this hypothesis we measured plasma concentrations of atrial natriuretic factor (ANF), renin, adrenaline (ADR) and noradrenaline (NADR) on admission and at 1 h and 4 h in 32 patients undergoing streptokinase treatment within 6 h of myocardial infarction. Fractional changes (FC) in hormone levels were calculated: e.g. ANFO-ANF4/ANFO. Resolution of ST segment elevation at 4 h was the primary measure of reperfusion. Sixteen patients showed ST segment resolution. There was no difference in hormone levels at baseline between reperfused and non-reperfused patients. Fractional changes in ANF, renin and ADR were similar in both groups. NADR fell from admission to 4 h in reperfused patients but rose in non-reperfused (FC 0.28 vs -0.10; P = 0.054). There was no difference in the changes in pulse rate or blood pressure from admission to 4 h between the two groups. Thus there is no evidence that early reperfusion acutely alters the release of ANF, renin or ADR to myocardial infarction. Although plasma NADR tended to fall acutely in reperfused patients this was not accompanied by other markers of sympathetic withdrawal.

    Rates of depression are reported to be between 22-33% in adults with HIV, which is double that of the general population. Depression negatively affects treatment adherence and health outcomes of those with medical illnesses. Further, it has been shown in adults that reducing depression may improve both adherence and health outcomes. To address the issues of depression and non-adherence, Health and Wellness (H&W) Cognitive Behavioral Therapy (CBT) and medication management (MM) treatment strategies have been developed specifically for youth living with both HIV and depression. H&W CBT is based on other studies with uninfected youth and upon research on adults with HIV. H&W CBT uses problem-solving, motivational interviewing, and cognitive-behavioral strategies to decrease adherence obstacles and increase wellness. The intervention is delivered in 14 planned sessions over a 6-month period, with three different stages of CBT. This paper summarizes the feasibility and acceptability data from an open depression trial with 8 participants, 16-24 years of age, diagnosed with HIV and with a Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) diagnosis of depression, conducted at two treatment sites in the Adolescent Trials Network (ATN). Both therapists and subjects completed a Session Evaluation Form (SEF) after each session, and results were strongly favorable. Results from The Quick Inventory of Depressive Symptomatology-Clinician (QIDS-C) also showed noteworthy improvement in depression severity. A clinical case vignette illustrates treatment response. Further research will examine the use of H&W CBT in a larger trial of youth diagnosed with both HIV and depression.

    Depression frequently co-occurs with paediatric obsessive-compulsive disorder (OCD), yet the clinical correlates and impact of depression on CBT outcomes remain unclear. The prevalence and clinical correlates of depression were examined in a paediatric specialist OCD-clinic sample (N = 295; Mean = 15 [7 - 18] years, 42 % female), using both dimensional (Beck Depression Inventory-youth; n = 261) and diagnostic (Development and Wellbeing Assessment; n = 127) measures of depression. The impact of depressive symptoms and suspected disorders on post-treatment OCD severity was examined in a sub-sample who received CBT, with or without SSRI medication (N = 100). Fifty-one per-cent of patients reported moderately or extremely elevated depressive symptoms and 26 % (95 % CI: 18 - 34) met criteria for a suspected depressive disorder. Depressive symptoms and depressive disorders were associated with worse OCD symptom severity and global functioning prior to CBT. Individuals with depression were more likely to be female, have had a psychiatric inpatient admission and less likely to be attending school (ps < 0.01). OCD and depressive symptom severity significantly decreased after CBT. Depressive symptoms and depressive disorders predicted worse post-treatment OCD severity (βs = 0.19 and 0.26, ps < 0.05) but became non-significant when controlling for pre-treatment OCD severity (βs = 0.05 and 0.13, ns). Depression is common in paediatric OCD and is associated with more severe OCD and poorer functioning. However, depression severity decreases over the course of CBT for OCD and is not independently associated with worse outcomes, supporting the recommendation for treatment as usual in the presence of depressive symptoms.

    Background Cognitive performance deteriorates during extended wakefulness and circadian phase misalignment, and some individuals are more affected than others. Whether performance is affected similarly across cognitive domains, or whether cognitive processes involving Executive Functions are more sensitive to sleep and circadian misalignment than Alertness and Sustained Attention, is a matter of debate. Methodology/Principal Findings We conducted a 2 × 12-day laboratory protocol to characterize the interaction of repeated partial and acute total sleep deprivation and circadian phase on performance across seven cognitive domains in 36 individuals (18 males; mean ± SD of age = 27.6±4.0 years). The sample was stratified for the rs57875989 polymorphism in PER3, which confers cognitive susceptibility to total sleep deprivation. We observed a deterioration of performance during both repeated partial and acute total sleep deprivation. Furthermore, prior partial sleep deprivation led to poorer cognitive performance in a subsequent total sleep deprivation period, but its effect was modulated by circadian phase such that it was virtually absent in the evening wake maintenance zone, and most prominent during early morning hours. A significant effect of PER3 genotype was observed for Subjective Alertness during partial sleep deprivation and on n-back tasks with a high executive load when assessed in the morning hours during total sleep deprivation after partial sleep loss. Overall, however, Subjective Alertness and Sustained Attention were more affected by both partial and total sleep deprivation than other cognitive domains and tasks including n-back tasks of Working Memory, even when implemented with a high executive load. Conclusions/Significance Sleep loss has a primary effect on Sleepiness and Sustained Attention with much smaller effects on challenging Working Memory tasks. These findings have implications for understanding how sleep debt and circadian rhythmicity

    The present study aims to elucidate in a sequential manner the changes of the blood coagulation process at different phases of experimental schistosomiasis, comprising the pre-patent, acute, intermediate and chronic phases, and the effect of chemotherapeutic cure, at the acute and chronic phases, on reversion of changes related to the coagulation factors. Mice were infected with Schistosoma mansoni cercariae, and were divided into four groups. Blood samples from these groups were collected 32, 70, 100, and 140 days after infection, corresponding to the pre-patent, acute, intermediate and chronic phases, respectively. Simultaneously, other infected groups were given oxamniquine, 70 and 140 days after infection. At the same time as blood collection from infected and/or treated animal groups, other uninfected control animal groups were punctured and maintained under the same conditions as the infected animals. The vitamin-K-dependent clotting factors were found to be more sensitive to infection at different phases, while factors VIII and XI presented hyperactivity. Results obtained 90 days after chemotherapeutic treatment with oxamniquine, administered at the acute and chronic phases, presented noticeable reversion of the main alterations in the coagulation mechanism. The present study provides unquestionable data on the development of hemostatic changes throughout the course of S. mansoni infection.

    Objective. This study compared acute and late effect of single-bout endurance training (ET) and high-intensity interval training (HIIT) on the plasma levels of four inflammatory cytokines and C-reactive protein and insulin-like growth factor 1. Design. Cohort study with repeated-measures design. Methods. Seven healthy untrained volunteers completed a single bout of ET and HIIT on a cycle ergometer. ET and HIIT sessions were held in random order and at least 7 days apart. Blood was drawn before the interventions and 30 min and 2 days after the training sessions. Plasma samples were analyzed with ELISA for the interleukins (IL), IL-1β, IL-6, and IL-10, monocyte chemoattractant protein-1 (MCP-1), insulin growth factor 1 (IGF-1), and C-reactive protein (CRP). Statistical analysis was with Wilcoxon signed-rank tests. Results. ET led to both a significant acute and long-term inflammatory response with a significant decrease at 30 minutes after exercise in the IL-6/IL-10 ratio (−20%; p = 0.047) and a decrease of MCP-1 (−17.9%; p = 0.03). Conclusion. This study demonstrates that ET affects the inflammatory response more adversely at 30 minutes after exercise compared to HIIT. However, this is compensated by a significant decrease in MCP-1 at two days associated with a reduced risk of atherosclerosis. PMID:27212809

    Brain areas involved in heart autonomic control are not well characterized. Insulae have been proposed as control centers. A lesion in these areas may induce a cardiac autonomic dysfunction (arrhythmias, atrioventricular conduction abnormalities). Asystolia has not been previously reported. A 65-year-old man suffered an acute ischemia of the right middle cerebral artery (MCA) territory. NIHSS score was 19 points. Brain CT scan was normal. Transcranial Doppler (TCD) showed occlusion of the right MCA. Fibrinolysis was initiated 135 minutes after stroke onset with TCD monitoring. Twenty minutes later he suffered cardiac arrest with asystolia trace in the ECG monitor. Fibrinolysis was stopped during resuscitation. Four minutes later, he recovered with the same NIHSS score. Aggressive resuscitation maneuvers were not necessary. A repeated brain CT scan showed infarct signs in the whole MCA territory and a new TCD did not show any change. Serial blood analyses including cardiac nzymes were normal. The patient experienced four brief cardiac arrests in the next nine hours, so a temporary cardiac pacemaker was placed for four days. He was treated with aspirin and was discharged 14 days after admission. He has not experienced recurrences during a 6-month follow-up. We could not diagnose the etiology of the cardiac arrests. All the episodes occurred in the acute stroke stage and arrhythmia, atrioventricular block, myocardial ischemia or structural lesions were not found in the cardiac study. We propose that ischemia in the right insula induced sudden and transitory interruptions of the sympathetic cardiac tone. PMID:12677486

    Background Fractional exhaled nitric oxide (FENO) levels are increased in children with asthma and in infants with recurrent wheezing, but the role of FENO in the acute phase of bronchiolitis is still not defined. Objective The aim of this study is to evaluate FENO values in the acute phase of bronchiolitis, compare them with healthy infants, and relate those values with the appearance of other wheezing episodes. Methods FENO values were determined in infants between 2 months and 2 years affected with RVS bronchiolitis by offline method. The FENO values collected in the acute phase were related with the respiratory clinical symptoms presented in the 2 years following the episode. Results A total of 30 patients were recruited: 15 in the bronchiolitis group and 15 in the control group. The average of the FENO values in the acute phase was 18.74 ppb (range 2–88) in the bronchiolitis group, and 8.75 ppb (range 2–24) in the control group. However, these results showed no significant statistical differences (p=0.176). Nevertheless, we found a positive correlation between the FENO values and the clinical score (Downes) of the bronchiolitis episode (p=0.023). In infants that presented other wheezing episodes in the 2 years after, the average of FENO in the acute phase of the first episode was 23.1 ppb (average of 10.25 ppb) versus 8.4 ppb (average 5.4 ppb) in the group of patients with no other episodes. The comparison of averages has no statistical significance. Conclusion We found no differences in FENO between infants with bronchiolitis and healthy ones. The FENO values in the acute phase seems to be related to the severity of the disease but do not predict the appearance of wheezing episodes in the following 2 years. PMID:22768386

    Studies developed by our group in the last years have shown the involvement of TGF-β in acute and chronic Chagas heart disease, with elevated plasma levels and activated TGF-β cell signaling pathway as remarkable features of patients in the advanced stages of this disease, when high levels of cardiac fibrosis is present. Imbalance in synthesis and degradation of extracellular matrix components is the basis of pathological fibrosis and TGF-β is considered as one of the key regulators of this process. In the present study, we investigated the activity of the TGF-β signaling pathway, including receptors and signaling proteins activation in the heart of animals experimentally infected with Trypanosoma cruzi during the period that mimics the acute phase of Chagas disease. We observed that T. cruzi-infected animals presented increased expression of TGF-β receptors. Overexpression of receptors was followed by an increased phosphorylation of Smad2/3, p38 and ERK. Furthermore, we correlated these activities with cellular factors involved in the fibrotic process induced by TGF-β. We observed that the expression of collagen I, fibronectin and CTGF were increased in the heart of infected animals on day 15 post-infection. Correlated with the increased TGF-β activity in the heart, we found that serum levels of total TGF-β were significantly higher during acute infection. Taken together, our data suggest that the commitment of the heart associates with increased activity of TGF-β pathway and expression of its main components. Our results, confirm the importance of this cytokine in the development and maintenance of cardiac damage caused by T. cruzi infection.

    Objective. Assess impact of Medicare Part D benefit phases on adherence with evidence-based medications after hospitalization for an acute myocardial infarction. Data Source. Random 5 percent sample of Medicare beneficiaries. Study Design. Difference-in-difference analysis of drug adherence by AMI patients stratified by low-income subsidy (LIS) status and benefit phase. Data Collection/Extraction Methods. Subjects were identified with an AMI diagnosis in Medicare Part A files between April 2006 and December 2007 and followed until December 2008 or death (N = 8,900). Adherence was measured as percent of days covered (PDC) per month with four drug classes used in AMI treatment: angiotensin-converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARBs), beta-blockers, statins, and clopidogrel. Monthly exposure to Part D benefit phases was calculated from flags on each Part D claim. Principal Findings. For non-LIS enrollees, transitioning from the initial coverage phase into the Part D coverage gap was associated with statistically significant reductions in mean PDC for all four drug classes: statins (−7.8 percent), clopidogrel (−7.0 percent), beta-blockers (−5.9 percent), and ACE inhibitor/ARBs (−5.1 percent). There were no significant changes in adherence associated with transitioning from the gap to the catastrophic coverage phase. Conclusions. As the Part D doughnut hole is gradually filled in by 2020, Medicare Part D enrollees with critical diseases such as AMI who rely heavily on brand name drugs are likely to exhibit modest increases in adherence. Those reliant on generic drugs are less likely to be affected. PMID:23742013

  9. Acute tubular necrosis (ATN) presenting with an unusually prolonged period of marked polyuria heralded by an abrupt oliguric phase

    2014-01-01

    A 50-year-old African-American man presented with acute tubular necrosis (ATN) secondary to hypotension from non-typhoid Salmonella gastroenteritis and bacteraemia. The oliguric phase lasted only 24 h followed by prolonged polyuria for 20 days, with urine output in excess of 16 L/day at maximum. As indexed in PubMed this is only the second published case of this nature since 1974, in which an abrupt oliguric phase of 24 h or less heralded prolonged polyuria in ATN. The diagnosis is challenging as fractional excretion of sodium early in the clinical course and rapid normalisation of serum creatinine with intravenous fluids (IVF) may point towards prerenal azotaemia resulting in a premature discharge from hospital. Patients with an abrupt oliguric phase may suffer a secondary renal insult from the profound fluid loss that is to follow and may need inpatient monitoring with supplemental IVF to prevent deleterious outcomes.

    Hematological malignancies present abnormal blood cells that may have altered functions. This study aimed to evaluate nutritional status, acute phase proteins, parameters of cell's functionality, and oxidative stress of patients with hematological malignancies, providing a representation of these variables at diagnosis, comparisons between leukemias and lymphomas and establishing correlations. Nutritional status, C-reactive protein (CRP), albumin, phagocytic capacity and superoxide anion production of mononuclear cells, lipid peroxidation and catalase activity in plasma were evaluated in 16 untreated subjects. Main diagnosis was acute leukemia (n = 9) and median body mass index (BMI) indicated overweight (25.6 kg/m(2)). Median albumin was below (3.2 g/dL) and CRP above (37.45 mg/L) the reference values. Albumin was inversely correlated with BMI (r = -0.53). Most patients were overweight before the beginning of treatment and had a high CRP/albumin ratio, which may indicate a nutrition inflammatory risk. BMI values correlated positively with lipid peroxidation and catalase activity. A strong correlation between catalase activity and lipid peroxidation was found (r = 0.75). Besides the elevated BMI, these patients also have elevated CRP values and unexpected relations between nutritional status and albumin, reinforcing the need for nutritional counseling during the course of chemotherapy, especially considering the correlations between oxidative stress parameters and nutritional status evidenced here.

    Background Recently, the application of meditative practices to the treatment of depressive disorders has met with increasing clinical and scientific interest, due to a lower side-effect burden, potential reduction of polypharmacy, as well as theoretical considerations that such interventions may target some of the cognitive roots of depression. We aimed to determine the state of the evidence supporting this application. Methods Randomized, controlled trials of techniques meeting the Agency for Healthcare Research and Quality (AHRQ) definition of meditation, for participants suffering from clinically diagnosed depressive disorders, not currently in remission, were selected. Meditation therapies were separated into praxis (i.e. how they were applied) components, and trial outcomes were reviewed. Results Eighteen studies meeting inclusionary criteria were identified, encompassing seven distinct techniques and 1173 patients, with Mindfulness-Based Cognitive Therapy comprising the largest proportion. Studies including patients suffering from acute major depressive episodes (N = 10 studies), and those with residual subacute clinical symptoms despite initial treatment (N = 8), demonstrated moderate to large reductions in depression symptoms within group, and relative to control groups. There was significant heterogeneity of techniques and trial designs. Conclusions A substantial body of evidence indicates that meditation therapies may have salutary effects on patients suffering from clinical depressive disorders during the acute and subacute phases of treatment. Due to methodological deficiences and trial heterogeneity, large-scale, randomized controlled trials with well-described comparator interventions and measures of expectation are needed to clarify the role of meditation in the depression treatment armamentarium.

    Rotaviral enteritis has emerged as a major cause of morbidity and mortality in piglets during their post-natal life. The present study was carried out to examine high-mobility group box 1 (HMGB1) protein, acute phase response and oxidative stress indices in the serum of suckling piglets suffering from enteritis with or without association of porcine group A rotavirus infection. The present investigation utilized 23 clinical cases with signs of acute enteritis and 12 more healthy piglets of a similar age group as control animals. Out of 23 enteritis cases, 12 cases were found to be positive for porcine group A rotavirus infection as confirmed by reverse transcription-polymerase chain reaction (RT-PCR) using specific primers for group A rotavirus, and the rest were found negative. The acute enteritis cases in piglets were associated with an elevated level of HMGB1 protein and serum haptoglobin and ceruloplasmin suggestive of an acute phase response. Among the oxidative stress indices, the concentrations of malondialdehyde (MDA) and nitric oxide (NO) in serum were significantly increased. A pronounced drop of total antioxidant capacity and the activity of antioxidant enzymes such as catalase and superoxide dismutase in the serum of piglets suffering from acute enteritis compared to healthy ones were also noticed. The alterations in HMGB1 protein, acute phase response and oxidative stress indices were more pronounced in cases with the involvement of porcine rotavirus as compared to rotavirus-negative cases. It is concluded that HMGB1 protein, markers of oxidative stress and acute phase proteins might play an important role in the aetiopathogenesis of porcine diarrhoea caused by rotavirus and might be true markers in diagnosing the conditions leading to the extension of the prompt and effective therapeutic care.

    The intact crossed pathway via which the contralesional hemisphere responds to the ipsilesional somatosensory input has shown to be affected by unilateral stroke. The aim of this study was to investigate the plasticity of the intact crossed pathway in response to different intensities of stimulation in a rodent photothrombotic stroke model. Using optical intrinsic signal imaging, an overall increase of the contralesional cortical response was observed in the acute phase (≤48 hours) after stroke. In particular, the contralesional hyperactivation is more prominent under weak stimulations, while a strong stimulation would even elicit a depressed response. The results suggest a distinct stimulation-response pattern along the intact crossed pathway after stroke. We speculate that the contralesional hyperactivation under weak stimulations was due to the reorganization for compensatory response to the weak ipsilateral somatosensory input. PMID:27144032

    Chagas' disease, or American trypanosomiasis, is caused by the protozoan parasite Trypanasoma cruzi. It is estimated that 15,000 new cases of congenital T. cruzi transmission occur in the Americas each year. The aim of this study was to estimate the rate of congenital T. cruzi infection in infants born to infected women living in Ushuaia, Argentina, as well to assess a serologic test using Shed Acute Phase Antigen (SAPA) for a timely diagnosis of congenital infection. The rate of congenital infection among children in the study was 4.4% (3/68). Our results show that for infants younger than 30 days of age, matched blood samples from mother and infant were capable of identifying congenital transmission of infection using an enzyme-linked immunosorbent assay with SAPA. For infants older than 3 months, congenital infection could be ruled out using the same procedure. PMID:20064996

    We present an analysis of the Fabry{endash}P{acute e}rot response to a phase-modulated light in the reflection mode, by considering the general problem of the lock-in detection at the {ital p}th harmonics of the rf modulating frequency. Suitable frequency modulation conditions for servo-locking purposes are obtained and the values of modulation index which maximize the sensitivity for the first, third, and fifth harmonics are found. Moreover, we investigate the effects of the residual amplitude modulation introduced by the electro-optic frequency modulator, the presence of laser amplitude and frequency noise, and the dependence of the achievable closed-loop frequency fluctuation spectrum on the modulation index and detection noise. {copyright} {ital 1996 American Institute of Physics.}

    The concentrations and sequential changes of some acute phase proteins, factor B, and lysozyme have been assayed in recurrent oral ulceration and Behçet's syndrome. C9 was elevated in both groups of patients and was the sensitive index of disease activity; however, it failed to discriminate between the three types of recurrent oral ulcers and four types of Behçet's syndrome. The level of alpha 1 acid glycoprotein and lysozyme were significantly increased predominantly in the ocular type, whereas factor B was significantly increased especially in the neurological type of Behçet's syndrome. It is suggested that the changes in the concentrations of some plasma proteins may help our understanding of tissue involvement in Behçet's syndrome, as well as in the selection of therapeutic agents in this disease.

    In a sample of 100 patients with recurrent major depression, we collected depression severity data early and late in acute-phase cognitive therapy, plus a wide range of psychosocial variables that have been studied extensively in depression research, including measures of interpersonal, cognitive, and social functioning, and personality traits using an inventory that is linked with the Big-Three tradition in personality assessment theory. By assessing this broad range of variables in a single study, we could examine the extent to which relations of these variables with depression were due to (a) a common factor shared across this diverse set of constructs, (b) factors shared among each type of construct (personality vs. psychosocial measures), or (c) specific aspects of the individual measures. Only the most general factor shared across the personality and psychosocial variables predicted later depression. PMID:14632375

    Hydrolytic enzymes are the major constituents of alveolar macrophages (AM) and have been shown to be involved in many aspects of the inflammatory pulmonary response. The aim of this study was to evaluate the role of lysosomal enzymes in the acute phase of hypersensitivity pneumonitis (HPs). An experimental study on AM lysosomal enzymes of an HP-guinea-pig model was performed. The results obtained both in vivo and in vitro suggest that intracellular enzymatic activity decrease is, at least partly, due to release of lysosomal enzymes into the medium. A positive but slight correlation was found between extracellular lysosomal activity and four parameters of lung lesion (lung index, bronchoalveolar fluid total (BALF) protein concentration, BALF LDH and BALF alkaline phosphatase activities). All the above findings suggest that the AM release of lysosomal enzymes during HP is a factor involved, although possibly not the only one, in the pulmonary lesions appearing in this disease.

    The purpose of this study was to examine ethanol's delayed effects (termed hangover) using conditioned place testing. Four groups of rats received a single pairing of a distinctive environment (tactile and visual) 10 h after injection with ethanol (0, 2, 3, 4 g/kg, i.p. ) or saline in a counterbalanced design. Rats receiving 3 and 4 g/kg ethanol showed a conditioned place aversion to ethanol hangover. Conditioning 10 h after 0 or 2 g/kg ethanol did not produce a significant place preference or aversion. The results suggest that the hangover following an acute injection of high doses of ethanol (3-4 g/kg) produces a significant and dose-related conditioned place aversion in the rat.

  1. Establishment of a Persistent Escherichia coli Reservoir during the Acute Phase of a Bladder Infection

    The vast majority of urinary tract infections are caused by strains of uropathogenic Escherichia coli that encode filamentous adhesive organelles called type 1 pili. These structures mediate both bacterial attachment to and invasion of bladder epithelial cells. However, the mechanism by which type 1 pilus-mediated bacterial invasion contributes to the pathogenesis of a urinary tract infection is unknown. Here we show that type 1-piliated uropathogens can invade the superficial epithelial cells that line the lumenal surface of the bladder and subsequently replicate, forming massive foci of intracellular E. coli termed bacterial factories. In response to infection, superficial bladder cells exfoliate and are removed with the flow of urine. To avoid clearance by exfoliation, intracellular uropathogens can reemerge and eventually establish a persistent, quiescent bacterial reservoir within the bladder mucosa that may serve as a source for recurrent acute infections. These observations suggest that urinary tract infections are more chronic and invasive than generally assumed. PMID:11402001

    The acute phase response as indicated by serum haptoglobin and total haemolytic complement activity (CH50) was measured in 72 cross-bred steer calves purchased at sales in Ontario. During the 28 day (d) trial, 18 steers were randomly assigned to each of the following groups: 1) control; 2) vaccinated (Infectious Bovine Rhinotracheitis, Parainfluenza-3, Bovine Viral Diarrhea, Bovine Respiratory Synctial Virus vaccine plus Pasteurella haemolytica vaccine); 3) supplemental chelated Cr (0.14 mg/kg); and 4) Cr plus vaccines. Haptoglobin concentrations were low at arrival, increased (P < 0.05) on day 7, and returned to near initial levels (P > 0.05) by day 14. Supplemental Cr reduced (P < 0.05) haptoglobin on day 7 when morbidity was highest. Following antibiotic treatment for respiratory disease haptoglobin was lower (P < 0.05) than during morbidity; however, during morbidity, haptoglobin concentrations were not greater in sick calves (P > 0.05) than in healthy calves. Complement activity was lowest on day 7 (P < 0.05) and peaked on day 14 (P < 0.05). Complement activity tended to be lower on day 7 for vaccine, Cr, and Cr+ vaccine groups; however, the difference from controls was not significant (P > 0.10). Complement activity did not increase on day 14 (P > 0.05) with Cr supplementation as in other treatments. Morbid calves had lower (P < 0.05) CH50 activity than healthy calves on day 14. Following antibiotic treatment, the Cr-supplemented group had higher (P < 0.05) CH50 than during morbidity. In general, chromium supplementation reduced the acute phase response in newly arrived feeder calves. PMID:8548694

    Preeclampsia is an inflammatory-mediated hypertensive disorder of pregnancy and seems to be an early indicator of increased cardiovascular risk, but mechanisms underlying this association are unclear. In this study, we identified levels of circulating inflammatory markers and dynamic changes in the systemic acute-phase response in 44 women with a history of severe early-onset preeclampsia, compared with 29 controls with only uneventful pregnancies at 1.5 to 3.5 years postpartum. Models used were in vivo seasonal influenza vaccination and in vitro whole-blood culture with T-cell stimulants and the toll-like receptor-4 ligand lipopolysaccharide. Outcome measures were C-reactive protein, interleukin-6 (IL-6), IL-18, fibrinogen, myeloperoxidase, and a panel of 13 cytokines representative of the innate and adaptive inflammatory response, in addition to established cardiovascular markers. The in vivo acute-phase response was higher for women with previous preeclampsia than that for controls without such a history, although only significant for C-reactive protein (P=0.04). Preeclampsia was associated with higher IL-1β (P<0.05) and IL-8 (P<0.01) responses to T-cell activation. Hierarchical clustering revealed 2 distinct inflammatory clusters associated with previous preeclampsia: an adaptive response cluster associated with increased C-reactive protein and IL-6 before and after vaccination, increased weight, and low high-density lipoprotein cholesterol; and a toll-like receptor-4 mediated the cluster associated with increased IL-18 before and after vaccination but not associated with other cardiovascular markers. Furthermore, we found interactions between previous preeclampsia, common TLR4 gene variants, and the IL-18 response to vaccination. In conclusion, preeclampsia is associated with alterations in the inflammatory response postpartum mostly independent of other established cardiovascular risk markers.

    The present study aimed to investigate the diagnostic and prognostic importance of oxidative stress biomarkers and acute phase proteins in urinary tract infection (UTI) in camels. We describe the clinical, bacteriological and biochemical findings in 89 camels. Blood and urine samples from diseased (n = 74) and control camels (n = 15) were submitted to laboratory investigations. The urine analysis revealed high number of RBCS and pus cells. The concentrations of serum and erythrocytic malondialdehyde (sMDA & eMDA), Haptoglobin (Hp), serum amyloid A (SAA), Ceruloplasmin (Cp), fibrinogen (Fb), albumin, globulin and interleukin 6 (IL-6) were higher in diseased camels when compared to healthy ones. Catalase, super oxide dismutase and glutathione levels were lower in diseased camels when compared with control group. Forty one of 74 camels with UTI were successfully treated. The levels of malondialdehyde, catalase, super oxide dismutase, glutathione, Hp, SAA, Fb, total protein, globulin and IL-6 were associated with the odds of treatment failure. The MDA showed a great sensitivity (Se) and specificity (Sp) in predicting treatment failure (Se 85%/Sp 100%) as well as the SAA (Se 92%/Sp 87%) and globulin levels (Se 85%/Sp 100%) when using the cutoffs that maximizes the sum of Se + Sp. Multivariate logistic regression analysis revealed that two models had a high accuracy to predict failure with the first model including sex, sMDA and Hp as covariates (area under the receiver operating characteristic curve (AUC) = 0.92) and a second model using sex, SAA and Hp (AUC = 0.89). Conclusively, the oxidative stress biomarkers and acute phase proteins could be used as diagnostic and prognostic biomarkers in camel UTI management. Efforts should be forced to investigate such biomarkers in other species with UTI. PMID:26587339

    Our objective was to develop a lipopolysaccharide (LPS) inflammation model in calves to evaluate the acute-phase response with respect to the release of pro-inflammatory cytokines and acute-phase proteins, fever development and sickness behaviour. Fourteen 4-week-old male Holstein Friesian calves were included and randomly assigned to a negative control group (n=3) and an LPS-challenged group (n=11). The latter received an intravenous bolus injection of 0.5 μg of LPS/kg body weight. Blood collection and clinical scoring were performed at 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12, 18, 24, 28, 32, 48, 54 and 72 h post LPS administration (p.a.). In the LPS group, the following clinical signs were observed successively: tachypnoea (on average 18 min p.a.), decubitus (29 min p.a.), general depression (1.75 h p.a.), fever (5h p.a.) and tachycardia (5h p.a.). Subsequent to the recovery from respiratory distress, general depression was prominent, which deteriorated when fever increased. One animal did not survive LPS administration, whereas the other animals recovered on average within 6.1h p.a. Moreover, the challenge significantly increased plasma concentrations of tumour necrosis factor-α, interleukin 6, serum amyloid A and haptoglobin, with peaking levels at 1, 3.5, 24 and 18 h p.a., respectively. The present LPS model was practical and reproducible, caused obvious clinical signs related to endotoxemia and a marked change in the studied inflammatory mediators, making it a suitable model to study the immunomodulatory properties of drugs in future research.

    Protein-energy malnutrition (PEM), present in 12%-19% of stroke patients upon hospital admission, appears to be a detrimental comorbidity factor that impairs functional outcome, but the mechanisms are not fully elucidated. Because ischemic brain injury is highly temperature-sensitive, the objectives of this study were to investigate whether PEM causes sustained changes in temperature that are associated with an inflammatory response. Activity levels were recorded as a possible explanation for the immediate elevation in temperature upon introduction to a low protein diet. Male, Sprague-Dawley rats (7 weeks old) were fed a control diet (18% protein) or a low protein diet (PEM, 2% protein) for either 7 or 28 days. Continuous core temperature recordings from bioelectrical sensor transmitters demonstrated a rapid increase in temperature amplitude, sustained over 28 days, in response to a low protein diet. Daily mean temperature rose transiently by day 2 (p = 0.01), falling to normal by day 4 (p = 0.08), after which mean temperature continually declined as malnutrition progressed. There were no alterations in activity mean (p = 0.3) or amplitude (p = 0.2) that were associated with the early rise in mean temperature. Increased serum alpha-2-macroglobulin (p < 0.001) and decreased serum albumin (p ≤ 0.005) combined with a decrease in serum alpha-1-acid glycoprotein (p < 0.001) suggest an atypical acute-phase response. In contrast, a low protein diet had no effect on the signaling pathway of the pro-inflammatory transcription factor, NFκB, in the hippocampus. In conclusion, PEM induces an aberrant and sustained acute-phase response coupled with long-lasting effects on body temperature.

    Preeclampsia is an inflammatory-mediated hypertensive disorder of pregnancy and seems to be an early indicator of increased cardiovascular risk, but mechanisms underlying this association are unclear. In this study, we identified levels of circulating inflammatory markers and dynamic changes in the systemic acute-phase response in 44 women with a history of severe early-onset preeclampsia, compared with 29 controls with only uneventful pregnancies at 1.5 to 3.5 years postpartum. Models used were in vivo seasonal influenza vaccination and in vitro whole-blood culture with T-cell stimulants and the toll-like receptor-4 ligand lipopolysaccharide. Outcome measures were C-reactive protein, interleukin-6 (IL-6), IL-18, fibrinogen, myeloperoxidase, and a panel of 13 cytokines representative of the innate and adaptive inflammatory response, in addition to established cardiovascular markers. The in vivo acute-phase response was higher for women with previous preeclampsia than that for controls without such a history, although only significant for C-reactive protein (P=0.04). Preeclampsia was associated with higher IL-1β (P<0.05) and IL-8 (P<0.01) responses to T-cell activation. Hierarchical clustering revealed 2 distinct inflammatory clusters associated with previous preeclampsia: an adaptive response cluster associated with increased C-reactive protein and IL-6 before and after vaccination, increased weight, and low high-density lipoprotein cholesterol; and a toll-like receptor-4 mediated the cluster associated with increased IL-18 before and after vaccination but not associated with other cardiovascular markers. Furthermore, we found interactions between previous preeclampsia, common TLR4 gene variants, and the IL-18 response to vaccination. In conclusion, preeclampsia is associated with alterations in the inflammatory response postpartum mostly independent of other established cardiovascular risk markers. PMID:26711734

    The current study investigated the effectiveness of a combined mindfulness-CBT group therapy program for women with binge eating problems. Questionnaires were completed by group participants pre-program (n = 30), post-program (n = 30) and 3 month follow-up (n = 28). Significant reductions between pre- and post-program scores were found on standardised measures assessing binge eating, dieting, and body image dissatisfaction, with all reductions maintained at follow-up. Qualitative interviews with 16 women following completion of the program revealed the value of mindfulness in improving eating behaviour through increased self-awareness. This exploratory study supports the value of adding mindfulness to the more commonly utilised CBT-based programs for binge eating.

  9. Pedophilia: the problem with diagnosis and limitations of CBT in treatment.

    PubMed

    Studer, Lea H; Aylwin, A Scott

    2006-01-01

    This paper asserts two main points. First, there is little reason to include pedophilia among the mental disorders of the Diagnostic and Statistical Manual (DSM). The diagnostic criteria as specified in the DSM-IV-TR (2000) are both over-inclusive in that all acts of child molestation warrant diagnosis, and under-inclusive in that individuals who have not acted upon, and who are not distressed by their sexual interest in children do not meet diagnostic criteria. On both sides of this debate there are problems. A diagnosis of pedophilia seems to "medicalize" an illegal behavior, or "criminalize" fantasy; depending on the diagnostic criteria used, or the use made of the diagnosis. Secondly, the typical CBT-based relapse prevention treatment for pedophilia, which represents current best practice, is reviewed. It is suggested that this, as a stand alone therapy, is suboptimal. CBT components are necessary but not sufficient for comprehensive therapy. It is imperative that process issues are given primacy in treatment programs. The common factors literature makes it clear that the therapeutic relationship is at least as potent a factor promoting change as the system or techniques that clinicians employ. Diagnosis per se is not required for adequate treatment of these individuals. For the CBT components, some offence specific information is required but that is a far cry from true diagnosis.

    There are high rates of comorbidity between heavy drinking and depressive symptoms among college students, often resulting in severe alcohol-related consequences. No empirically supported treatment exists that concurrently addresses both of these problems in this population. Research with college students has demonstrated that brief motivational interventions (BMIs) reduce heavy drinking and alcohol-related consequences, and that cognitive behavioral therapy for depression (CBT-D) is effective in reducing depressive symptoms. Thus, a program combining BMI and CBT-D appears ideal for college students with co-occurring binge drinking and depressive symptoms. This manuscript presents the rationale and format of a BMI + CBT-D treatment protocol for this population, and provides a case example of a female college student who received the protocol and experienced improvement in depressive symptoms, a reduction in alcohol use and alcohol-related negative consequences, and an increase in readiness to change alcohol consumption. We discuss theoretical and clinical implications of these findings, and suggest directions for future research. PMID:25170188

    Objective Little is known about the temporal variability of the alliance-symptom change and cohesion-symptom change relationships over the course of group therapy. These questions were examined in a sample of 373 clients receiving a transdiagnostic cognitive behavior therapy (tCBT), which culled the principle research-supported mechanisms of change for anxiety disorders. Method We examined relationships between the client versions of the Working Alliance Inventory and Group Cohesion Scale in predicting subsequent symptom change, as assessed by the state scale of the State-Trait Anxiety Inventory. Results Alliance and cohesion were significant predictors of next session anxiety scores. The alliance was consistently associated with anxiety symptoms (rs = −.152 to −.198, ps < .05), but cohesion only showed significant relationships with anxiety symptoms at sessions 8 and 10 (Session 8, r = −.233, p = .020, and 10, r = −.236, p = .027). Alliance-anxiety relations remained constant, whereas cohesion-anxiety relations substantially increased from earlier to later sessions. Discussion Differences that were obtained in the relation of alliance and cohesion with anxiety symptoms suggests that these processes have different roles within group tCBT. If replicated, the present findings would suggest that the dynamic relationships between alliance and cohesion and symptoms within group CBT for anxiety disorders have been an important omission in process-outcome studies.

    Based on a global survey of bacterial derived branched glycerol dialkyl glycerol tetraether (GDGT) membrane lipids in soils, it has been found that the degree of methylation and the degree of cyclisation of branched tetraethers (MBT and CBT, respectively) correlates with annual mean air temperature (MAT) and soil pH. This relation is used in the MBT-CBT proxy to reconstruct past annual MAT based on the distribution of branched GDGTs in ancient sediments. Although in the global soil dataset the best correlation of this proxy is with annual MAT, it remains unknown whether a seasonal bias in reconstructed temperatures could occur, such as towards a season of ‘optimal growth’ of the, as yet, unknown soil bacteria which produce branched GDGTs. To investigate this possibility, eight different soil plots from mid-latitudes in the USA, The Netherlands and the UK have been sampled for one year at regular intervals and analyzed for their branched GDGT content. In addition, for two soils, branched GDGTs present as core lipids (the presumed fossil pool) and intact polar lipids (the presumed extant pool) were analyzed to see if the concentration and distribution of GDGTs in the two pools differ. The results are compared with annual MAT as well as with continuously measured in situ soil temperature to see whether or not seasonally changing temperatures are recorded by these membrane lipids and whether this could lead to a bias in temperatures reconstructed using the MBT-CBT proxy.

    Research indicates that cognitive processes linked to the detection of threat stimuli are associated with poor attentional control, placing children and adolescents at increased risk for the development of anxious affect. The current study aimed to provide preliminary data to assess whether an intervention designed to improve attentional control (via working memory; WM) would lead to better performance in tests of WM and would be associated with positive changes in symptoms of trait and test anxiety, increased inhibitory control and reduced attention to threat. Forty adolescents aged 11-14 years who reported elevated anxiety and low attentional control were randomly allocated to a WM training or an active cognitive behavioural therapy (CBT) control group. Post intervention, WM training was associated with greater improvements (versus. CBT) in trained WM tasks. Both groups, however, reported fewer anxiety symptoms, demonstrated increased inhibitory control and a reduction in attentional biases to threat post intervention and these results were maintained at follow up. The study provides indicative evidence which suggests that WM training has similar benefits to a more traditional CBT intervention on reduced anxiety and attentional biases for threat. Future research should aim to replicate the findings in a large sample size and explore the broader impact of training on day-to-day functioning. In addition, further research is needed to identify which participants benefit most from different interventions (using baseline characteristics) on treatment compliance and outcome.

    In 120 patients with atherosclerosis, complicated in 43 patients by a haemorrhagic, in 47 patients by an ischaemic, and in 30 patients by a transient cerebral insult, phase analysis of platelet aggregation was performed by the turbidimetric method according to Born with graphic recording according to O'Brien. An increase in the platelet activity was found in ischaemic insult, manifesting itself by the occurrence of spontaneous aggregationin 60% of the cases, an acceleration of ADP-induced aggregation, and the second aggregation phase in all patients examined. A direct correlation was revealed between the secondary aggregation and the intensity of spontaneous and of ADP-induced aggregation, and the possibility of a transformation of the spontaneous into the secondary aggregation of platelets was demonstrated. Haemorrhagic insults were characterized by the absence of spontaneous and secondary aggregation and by the suppression of ADP-induced aggregation. In a transient insult, the mean values of the aggregatogram items did differ from normal. In vitro, the role of increased permeability of platelet membranes in the mechanism triggering off spontaneous aggregation and the second phase of ADP-induced aggregation was documented.

    Patients with acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS) may respond to treatment with epigenetic-modifying agents. Histone deacetylase inhibitors may synergize with hypomethylating agents. This phase 1 dose-escalation study was designed to determine the maximum tolerated dose, recommended phase 2 dose, safety and tolerability of vorinostat plus decitabine in patients with relapsed/refractory AML, newly-diagnosed AML, or intermediate- to high-grade MDS. Thirty-four patients received concurrent therapy with decitabine plus vorinostat and 37 received sequential therapy with decitabine followed by vorinostat. Twenty-nine patients had relapsed/refractory AML, 31 had untreated AML and 11 had MDS. The target maximum administered dose (MAD) of decitabine 20 mg/m(2) daily for 5 d plus vorinostat 400 mg/d for 14 d was achieved for concurrent and sequential schedules, with one dose-limiting toxicity (Grade 3 QTc prolongation) reported in the sequential arm. Common toxicities were haematological and gastrointestinal. Responses were observed more frequently at the MAD on the concurrent schedule compared with the sequential schedule in untreated AML (46% vs. 14%), relapsed/refractory AML (15% vs. 0%) and MDS (60% vs. 0%). Decitabine plus vorinostat given concurrently or sequentially appears to be safe and well-tolerated. Concurrent therapy shows promising clinical activity in AML or MDS, warranting further investigation.

    When delivered within 1 and in most cases 2 hours of permanent middle cerebral artery occlusion (pMCAO), mild sensory stimulation (intermittent single whisker stimulation) was shown to be completely neuroprotective according to assessment with multiple techniques 24 hours after pMCAO in a rodent model of ischemic stroke (Lay et al., 2010). The acute effect of stimulation treatment on the ischemic cortex however, had yet to be reported. Here we characterize cortical function and perfusion during the 120 minute whisker stimulation period in four experimental groups with treatment initiated 0, 1, 2 hours (protected groups) or 3 hours post-pMCAO (unprotected group) using multiple techniques. According to functional imaging, a gradual return of evoked whisker functional representation to baseline levels was initiated with treatment onset and completed within the treatment period. Evoked neuronal activity and reperfusion to the ischemic area also showed a gradual recovery in protected animals. Surprisingly, a similar recovery profile was observed in response to treatment in all protected animals, irrespective of treatment onset time. Non-stimulated pMCAO control group data demonstrate that reperfusion is not spontaneous. This makes the complete protection observed in the majority of animals stimulated at 2 hours post-pMCAO even more surprising as these animals recovered despite having been in this severely ischemic state for two full hours. In summary, when delivered within a 2 hour window post- pMCAO, whisker stimulation treatment initiated reperfusion and a gradual recovery of cortical function that was completed or nearly completed within the treatment period.

    Earth's climate experienced dramatic changes throughout the last 65 Ma. Starting at the Paleocene/Eocene thermal maximum, the global climate underwent a gradual cooling that eventually resulted in the glaciations in the Neogene. Most reconstructions of climate variability are derived from the marine realm using global deep sea oxygen isotope curves or molecular paleotemperature proxies. In contrast, only little information on the changes of the continental climate is available, which is mainly due to a lack of continuous high resolution records and suitable quantitative temperature proxies. The MBT/CBT paleothermometer is a novel temperature proxy based on temperature-driven changes in the branched glycerol dialkyl glycerol tetraether (GDGT) content of soil-living bacteria. These changes have been demonstrated to correlate well with ambient air temperature and the MBT/CBT proxy has thus been used to reconstruct paleotemperature records of terrestrial as well as coastal marine sediments (1). In this study, we employed the MBT/CBT paleothermometer on a number of maar lake deposits that - due to their exceptional well preserved organic matter content and finely-laminated sediments - comprise excellent archives of a continental climate. The analysed lacustrine deposits were all situated in the middle European Tertiary volcanic belt and ranged in age from the Early Eocene to the Late Oligocene, allowing for the detailed reconstruction of climate evolution of the Central European continent. Calculated mean annual air temperatures (MAAT) of the Messel oil shale, deposited during the Eocene climate optimum, averaged at 25 °C. This agrees well with previous temperature estimates based on paleontological observations, suggesting a paratropical climate in Eocene Central Europe with an average air temperature of ca. 25-30 °C (2). In contrast, to the green house period of the Early Eocene, the climate of the Oligocene was significantly cooler reflected by low MAAT of 8-15

  20. Quantifying factors determining the rate of CTL escape and reversion during acute and chronic phases of HIV infection

    Human immunodeficiency virus (HIV) often evades cytotoxic T cell (CTL) responses by generating variants that are not recognized by CTLs. However, the importance and quantitative details of CTL escape in humans are poorly understood. In part, this is because most studies looking at escape of HIV from CTL responses are cross-sectional and are limited to early or chronic phases of the infection. We use a novel technique of single genome amplification (SGA) to identify longitudinal changes in the transmitted/founder virus from the establishment of infection to the viral set point at 1 year after the infection. We find that HIV escapes from virus-specific CTL responses as early as 30-50 days since the infection, and the rates of viral escapes during acute phase of the infection are much higher than was estimated in previous studies. However, even though with time virus acquires additional escape mutations, these late mutations accumulate at a slower rate. A poor correlation between the rate of CTL escape in a particular epitope and the magnitude of the epitope-specific CTL response suggests that the lower rate of late escapes is unlikely due to a low efficacy of the HIV-specific CTL responses in the chronic phase of the infection. Instead, our results suggest that late and slow escapes are likely to arise because of high fitness cost to the viral replication associated with such CTL escapes. Targeting epitopes in which virus escapes slowly or does not escape at all by CTL responses may, therefore, be a promising direction for the development of T cell based HIV vaccines.

    The outcome of intracerebral hemorrhage (ICH) is mainly determined by the volume of the hemorrhage core and the secondary brain damage to penumbral tissues due to brain swelling, microcirculation disturbance and inflammation. The present study aims to investigate the protective effects of cerebrolysin on brain edema and inhibition of the inflammation response surrounding the hematoma core in the acute stage after ICH. The ICH model was induced by administration of type VII bacterial collagenase into the stratum of adult rats, which were then randomly divided into three groups: ICH + saline; ICH + Cerebrolysin (5 ml/kg) and sham. Cerebrolysin or saline was administered intraperitoneally 1 h post surgery. Neurological scores, extent of brain edema content and Evans blue dye extravasation were recorded. The levels of pro-inflammatory factors (IL-1β, TNF-α and IL-6) were assayed by Real-time PCR and Elisa kits. Aquaporin-4 (AQP4) and tight junction proteins (TJPs; claudin-5, occludin and zonula occluden-1) expression were measured at multiple time points. The morphological and intercellular changes were characterized by Electron microscopy. It is found that cerebrolysin (5 ml/kg) improved the neurological behavior and reduced the ipsilateral brain water content and Evans blue dye extravasation. After cerebrolysin treated, the levels of pro-inflammatory factors and AQP4 in the peri-hematomal areas were markedly reduced and were accompanied with higher expression of TJPs. Electron microscopy showed the astrocytic swelling and concentrated chromatin in the ICH group and confirmed the cell junction changes. Thus, early cerebrolysin treatment ameliorates secondary injury after ICH and promotes behavioral performance during the acute phase by reducing brain edema, inflammatory response, and blood-brain barrier permeability.

    Ciguatoxins (CTX) are polyether neurotoxins that target voltage-gated sodium channels and are responsible for ciguatera, the most common fish-borne food poisoning in humans. This study characterizes the global transcriptional response of mouse liver to a symptomatic dose (0.26 ng/g) of the highly potent Pacific ciguatoxin-1 (P-CTX-1). At 1 h post-exposure 2.4% of features on a 44K whole genome array were differentially expressed (p < or = 0.0001), increasing to 5.2% at 4 h and decreasing to 1.4% by 24 h post-CTX exposure. Data were filtered (/fold change/ > or = 1.5 and p < or = 0.0001 in at least one time point) and a trend set of 1550 genes were used for further analysis. Early gene expression was likely influenced prominently by an acute 4 degrees C decline in core body temperature by 1 h, which resolved by 8 h following exposure. An initial downregulation of 32 different solute carriers, many involved in sodium transport, was observed. Differential gene expression in pathways involving eicosanoid biosynthesis and cholesterol homeostasis was also noted. Cytochrome P450s (Cyps) were of particular interest due to their role in xenobiotic metabolism. Twenty-seven genes, mostly members of Cyp2 and Cyp4 families, showed significant changes in expression. Many Cyps underwent an initial downregulation at 1 h but were quickly and strongly upregulated at 4 and 24 h post-exposure. In addition to Cyps, increases in several glutathione S-transferases were observed, an indication that both phase I and phase II metabolic reactions are involved in the hepatic response to CTX in mice.

    The haematological changes and release of soluble mediators, particularly C-reactive protein (CRP) and nitric oxide (NO), during uncomplicated malaria have not been well studied, especially in Brazilian areas in which the disease is endemic. Therefore, the present study examined these factors in acute (day 0) and convalescent phase (day 15) patients infected with Plasmodium falciparum and Plasmodium vivax malaria in the Brazilian Amazon. Haematologic parameters were measured using automated cell counting, CRP levels were measured with ELISA and NO plasma levels were measured by the Griess reaction. Our data indicate that individuals with uncomplicated P. vivax and P. falciparum infection presented similar inflammatory profiles with respect to white blood cells, with high band cell production and a considerable degree of thrombocytopaenia during the acute phase of infection. Higher CRP levels were detected in acute P. vivax infection than in acute P. falciparum infection, while higher NO was detected in patients with acute and convalescent P. falciparum infections. Although changes in these mediators cannot predict malaria infection, the haematological aspects associated with malaria infection, especially the roles of platelets and band cells, need to be investigated further.

    Purpose: Acute radiation proctitis is the most relevant complication of pelvic radiation and is still mainly treated supportively. Considering the negative impact of acute proctitis symptoms on patients' daily activities and the potential relationship between the severity of acute radiation injury and late damage, misoprostol was tested in the prevention of acute radiation-induced proctitis. Methods and Materials: A total of 100 patients who underwent radiotherapy for prostate cancer were entered into this phase III randomized, placebo-controlled, double-blind study with misoprostol or placebo suppositories. Radiation-induced toxicity was evaluated weekly during radiotherapy using the Common Toxicity Criteria. Results: Between the placebo and the misoprostol groups, no significant differences in proctitis symptoms occurred: 76% of patients in each group had Grade 1 toxicity, and 26% in the placebo group and 36% in the misoprostol group had Grade 2 toxicity. No differences were found in onset or symptom duration. Comparing the peak incidence of patients' toxicity symptoms, significantly more patients experienced rectal bleeding in the misoprostol group (p = 0.03). Conclusion: Misoprostol given as a once-daily suppository did not decrease the incidence and severity of radiation-induced acute proctitis and may increase the incidence of acute bleeding.

    Porcine reproductive and respiratory syndrome (PRRS) virus (PRRSV) is the etiologic agent of PRRS, one of the most important diseases in swine worldwide. In the present work, the effects of different PRRSV strains were tested on a piglet experimental model to study the induced acute phase response. For this purpose, pigs (n=15 for each group) were intranasally inoculated with one of five PRRSV strains (isolates EU10, 12, 17, 18 from genotype 1 and isolate JA-142 from genotype 2). The acute phase response was monitored by measuring acute phase proteins (APPs). Specifically, the serum concentration of haptoglobin (Hp), C-reactive protein (CRP) and Pig-Major Acute Protein (Pig-MAP) was determined at 0, 3, 6, 9, 12, 15, 18 and 21 days p.i. Clinical signs and growth performance were also monitored during the experiment. All animals became viremic after inoculation during the study period. The APP response was heterogeneous and dependent on the strain, being strains EU10, EU 18 and JA-142 those that induced the highest response and the strongest clinical signs. In general, Hp was the most sensitive biomarker for PRRSV infection, CRP behaved as moderate and Pig-MAP was the less responsive during the course of PRRSV experimental infection. Hp and CRP were significantly discriminatory between infected and control pigs, but not Pig-MAP.

    Protein-energy malnutrition (PEM) is a common post-stroke problem. PEM can independently induce a systemic acute-phase response, and pre-existing malnutrition can exacerbate neuroinflammation induced by brain ischemia. In contrast, the effects of PEM developing in the post-ischemic period have not been studied. Since excessive inflammation can impede brain remodeling, we investigated the effects of post-ischemic malnutrition on neuroinflammation, the acute-phase reaction, and neuroplasticity-related proteins. Male, Sprague-Dawley rats were exposed to global forebrain ischemia using the 2-vessel occlusion model or sham surgery. The sham rats were assigned to control diet (18% protein) on day 3 after surgery, whereas the rats exposed to global ischemia were assigned to either control diet or a low protein (PEM, 2% protein) diet. Post-ischemic PEM decreased growth associated protein-43, synaptophysin and synaptosomal-associated protein-25 immunofluorescence within the hippocampal CA3 mossy fiber terminals on day 21, whereas the glial response in the hippocampal CA1 and CA3 subregions was unaltered by PEM. No systemic acute-phase reaction attributable to global ischemia was detected in control diet-fed rats, as reflected by serum concentrations of alpha-2-macroglobulin, alpha-1-acid glycoprotein, haptoglobin, and albumin. Acute exposure to the PEM regimen after global brain ischemia caused an atypical acute-phase response. PEM decreased the serum concentrations of albumin and haptoglobin on day 5, with the decreases sustained to day 21. Serum alpha-2-macroglobulin concentrations were significantly higher in malnourished rats on day 21. This provides the first direct evidence that PEM developing after brain ischemia exerts wide-ranging effects on mechanisms important to stroke recovery.

    The aim of the present study was to evaluate the psychometric properties of the Competence and Adherence Scale for Cognitive Behavioral Therapy (CAS-CBT). The CAS-CBT is an 11-item scale developed to measure adherence and competence in cognitive-behavioral therapy (CBT) for anxiety disorders in youth. A total of 181 videotapes from the treatment sessions in a randomized controlled effectiveness trial (Wergeland et al., 2014) comprising youth (N = 182, M age = 11.5 years, SD = 2.1, range 8-15 years, 53% girls, 90.7% Caucasian) with mixed anxiety disorders were assessed with the CAS-CBT to investigate interitem correlations, internal consistency, and factor structure. Internal consistency was good (Cronbach's alpha = .87). Factor analysis suggested a 2-factor solution with Factor 1 representing CBT structure and session goals (explaining 46.9% of the variance) and Factor 2 representing process and relational skills (explaining 19.7% of the variance). The sum-score for adherence and competence was strongly intercorrelated, r = .79, p < .001. Novice raters (graduate psychology students) obtained satisfactory accuracy (ICC > .40, n = 10 videotapes) and also good to excellent interrater reliability when compared to expert raters (ICC = .83 for adherence and .64 for competence, n = 26 videotapes). High rater stability was also found (n = 15 videotapes). The findings suggest that the CAS-CBT is a reliable measure of adherence and competence in manualized CBT for anxiety disorders in youth. Further research is needed to investigate the validity of the scale and psychometric properties when used with other treatment programs, disorders and treatment formats. (PsycINFO Database Record

    Computer-based training (CBT) development has evolved from electronic page turners to a sophisticated instructional environment. The use of numerous large image files, large digital audio files, and complex computer-generated graphics files places great demands on a system's capacity for binary storage (disk space). One solution is the use of compact disc-read only memory (CD-ROM). The explosive growth of CD-ROM players in the marketplace makes CD-ROM a viable delivery medium for CBT. Recently, a CBT package for radiation protection technicians at Los Alamos National Laboratory was produced on CD-ROM. The course is delivered on a multimedia system consisting of the following: MS DOS-based computer, CD-ROM player, high-resolution video graphics array monitor, scanned color images with graphic overlays, digital audio, and mouse interface. This paper will allow the reader to assess the appropriateness of CD-ROM for a specific project, report on lessons learned from the RPT project, demonstrate that CD-ROM is within reach of the average CBT developer, and provide guidelines for successfully developing CD-ROM based CBT. This paper can serve as a basic primer on how to adapt CD-ROM as a CBT medium. Some of the technical aspects that are discussed are listed here: CD-ROM basics for CBT development, availability of low-cost development environments, file organization, optimization of CD-ROM response times, effective use of digital audio and still frame graphics, and animation with CD-ROM.

    This phase I trial evaluated two schedules of escalating vorinostat in combination with decitabine every 28 days: (i) sequential or (ii) concurrent. There were three dose-limiting toxicities: grade 3 fatigue and generalized muscle weakness on the sequential schedule (n = 1) and grade 3 fatigue on the concurrent schedule (n = 2). The maximum tolerated dose was not reached on both planned schedules. The overall response rate (ORR) was 23% (three complete response [CR], two CR with incomplete incomplete blood count recovery [CRi], one partial response [PR] and two morphological leukemic free state [MLFS]). The ORR for all and previously untreated patients in the sequential arm was 13% (one CRi; one MLFS) and 0% compared to 30% (three CR; one CRi; one PR; one MLFS) and 36% in the concurrent arm (p = 0.26 for both), respectively. Decitabine plus vorinostat was safe and has clinical activity in patients with previously untreated acute myeloid leukemia. Responses appear higher with the concurrent dose schedule. Cumulative toxicities may limit long-term usage on the current dose/schedules.

    A phase 1 study was conducted to evaluate the safety, pharmacokinetics (PK), efficacy and pharmacogenetic characteristics of clofarabine in seven Japanese pediatric patients with relapsed/refractory acute lymphoblastic leukemia (ALL). Patients in Cohort 1 received clofarabine 30 mg/m(2)/day for 5 days, followed by 52 mg/m(2)/day for 5 days in subsequent cycles. Cohort 2 patients were consistently treated with 52 mg/m(2)/day for 5 days. No more than six cycles were performed. Every patient had at least one ≥Grade 3 adverse event (AE). AEs (≥Grade 3) related to clofarabine were anaemia, neutropenia, febrile neutropenia, thrombocytopenia, alanine aminotransferase increased, aspartate aminotransferase increased, haemoglobin decreased, and platelet (PLT) count decreased. C max and AUC of clofarabine increased in a dose-dependent fashion, but its elimination half-life (T 1/2) did not appear to be dependent on dose or duration of treatment. Clofarabine at 52 mg/m(2)/day shows similarly tolerable safety and PK profiles compared to those in previous studies. No complete remission (CR), CR without PLT recovery, or partial remission was observed. Since clofarabine is already used as a key drug for relapsed/refractory ALL patients in many countries, the efficacy of clofarabine in Japanese pediatric patients should be evaluated in larger study including more patients, such as by post-marketing surveillance.

    RG7356, a recombinant anti-CD44 immunoglobulin G1 humanized monoclonal antibody, inhibits cell adhesion and has been associated with macrophage activation in preclinical models. We report results of a phase I dose-escalation study of RG7356 in relapsed/refractory acute myeloid leukemia (AML).Eligible patients with refractory AML, relapsed AML after induction chemotherapy, or previously untreated AML not eligible for intensive chemotherapy were enrolled and received intravenous RG7356 at dosages ≤ 2400 mg every other week or ≤ 1200 mg weekly or twice weekly; dose escalation started at 300 mg.Forty-four patients (median age, 69 years) were enrolled. One dose-limiting toxicity occurred (grade 3 hemolysis exacerbation) after one 1200 mg dose (twice-weekly cohort). The majority of adverse events were mild/moderate. Infusion-related reactions occurred in 64% of patients mainly during cycle 1. Two patients experienced grade 3 drug-induced aseptic meningitis. Pharmacokinetics increased supraproportionally, suggesting a target-mediated drug disposition (TMDD) at ≥ 1200 mg. Two patients achieved complete response with incomplete platelet recovery or partial response, respectively. One patient had stable disease with hematologic improvement.RG7356 was generally safe and well tolerated. Maximum tolerated dose was not reached, but saturation of TMDD was achieved. The recommended dose for future AML evaluations is 2400 mg every other week. PMID:27081038

    Activation of the immune system to clear pathogens and mitigate infection is a costly process that might incur fitness costs. When vertebrates are exposed to pathogens, their first line of defense is the acute-phase response (APR), which consists of a suite of physiological and behavioral changes. The dynamics of the APR are relatively well investigated in mammals and domesticated birds but still rather unexplored in passerine birds. In this study, we injected male zebra finches (Taeniopygia guttata) with a bacterial endotoxin (lipopolysaccharide [LPS]) to assess the potential physiological, immunological, and behavioral responses during the time course of an APR and also to record any potential short-term effects by measuring the birds during the days after the expected APR. We found that LPS-injected zebra finches decreased activity and gained less body mass during the APR, compared to control individuals. In addition, LPS-injected birds increased their production of LPS-reactive antibodies and reduced their metabolic rate during the days after the expected APR. Our results show that zebra finches demonstrate sickness behaviors during an APR but also that physiological effects persist after the expected time course of an APR. These delayed effects might be either a natural part of the progression of an APR, which is probably true for the antibody response, or a short-term carryover effect, which is probably true for the metabolic response.

    Molecular characterization of Philadelphia chromosome-negative (Ph−) chronic myeloproliferative disorders, such as systemic mastocytosis (SM), has provided a clear rationale for investigating novel targeted therapies. The tyrosine kinase (TK) inhibitor dasatinib is 325-fold more potent against Bcr-Abl TK than imatinib in vitro, significantly inhibiting wild-type KIT and PDGFR-B TKs, and is active against cells carrying the mutant KIT-D816V gene. In this phase 2, open-label study, the efficacy of dasatinib (140 mg/day) was investigated in 67 patients with various Ph− myeloid disorders, including SM (N=33; 28 KIT-D816V positive). The overall response rate to dasatinib in patients with SM was 33%. Only two patients, one with SM-myelofibrosis and one with SM-chronic eosinophilic leukemia, achieved complete response (elimination of mastocytosis) lasting for 5 and 16 months, respectively. Both patients were negative for KIT-D816V mutation, had low tryptase levels, abnormal WBC counts, and anemia, and had failed prior therapy with erythropoietin. Additional 9 SM patients had symptomatic response, lasting 3 to 18+ months. Complete responses were achieved in two other patients (acute myeloid leukemia, hypereosinophilic syndrome). No responses were observed among patients with myelodysplastic syndromes and primary myelofibrosis. The majority of adverse events were grade 1/2. These data show that dasatinib may benefit a selected group of SM patients, primarily by improving their symptoms. PMID:18559612

    Changes in interleukin (IL)-1beta, IL-6 and IL-8 in serum, and their mRNA expression on neutrophils from a 4.6-month old Holstein young calf with bovine leukocyte adhesion deficiency (BLAD) during the acute phase were evaluated. IL-1beta concentrations in the serum of the calf with BLAD at age 143-162 days ranged from 8.7 to 16.6 ng/ml, whereas the values were less than 2.7 ng/ml in control calves. Serum IL-6 (0.04 ng/ml) was only detected on the 1st day when the animal was diagnosed with the BLAD. IL-1beta and IL-8 mRNA expression on neutrophils from the affected calf appeared to be similar to those of controls. Serum cytokine levels and their mRNA expression on neutrophils from the calf with BLAD appeared to be little affected by the deficient expression of beta(2)-integrin on leukocytes, and are considered to be modulated by the inflammatory stimuli.

    Effect of Calendula officinalis flower extract was investigated against experimentally induced thermal burns in rats. Burn injury was made on the shaven back of the rats under anesthesia and the animals were treated orally with different doses of the flower extract (20 mg, 100 mg and 200 mg/kg body weight). The animals treated with the extract showed significant improvement in healing when compared with the control untreated animals. The indicators of the wound healing such as collagen-hydroxyproline and hexosamine contents were significantly increased in the treated group indicating accelerated wound healing in the treated animals. The acute phase proteins-haptoglobin and orosomucoid which were increased due to burn injury were found to be decreased significantly in 200 mg/kg body weight extract treated animals. The antioxidant defense mechanism, which was decreased in the liver during burn injury, was found to be enhanced in treated animals. The lipid peroxidation was significantly lowered in the treated group when compared to control animals. Tissue damage marker enzymes- alkaline phosphatase, alanine and aspartate transaminases were significantly lowered in the treated groups in a dose dependant manner. The histopathological analyses of skin tissue also give the evidence of the increased healing potential of the extract after burn injury.

    Objectives. The changes in the serum levels of lipopolysaccharide binding protein (LBP) and sCD14 during cardiac surgery were followed in this study. Design. Thirty-four patients, 17 in each group, were randomly assigned to coronary artery bypass grafting surgery performed either with (“on-pump”) or without (“off-pump”) cardiopulmonary bypass. LBP and sCD14 were evaluated by ELISA. Results. The serum levels of LBP were gradually increased from the 1st postoperative day and reached their maximum on the 3rd postoperative day in both “on-pump” and “off-pump” patients (30.33±9.96 μg/mL; 37.99±16.58 μg/mL), respectively. There were no significant differences between “on-pump” and “off-pump” patients regarding LBP. The significantly increased levels of sCD14 from the 1st up to the 7th postoperative day in both “on-pump” and “off-pump” patients were found with no significant differences between these groups. No correlations between LBP and sCD14 and IL-6, CRP and long pentraxin PTX3 levels were found. Conclusions. The levels of LBP and sCD14 are elevated in cardiac surgical patients being similar in both groups. These molecules are not produced as acute phase proteins in these patients. PMID:18288274

    The acute-phase protein orosomucoid (ORM) exhibits a variety of activities in vitro and in vivo, notably modulation of immunity and transportation of drugs. We found in this study that mice lacking ORM1 displayed aberrant energy homeostasis characterized by increased body weight and fat mass. Further investigation found that ORM, predominantly ORM1, is significantly elevated in sera, liver, and adipose tissues from the mice with high-fat diet (HFD)-induced obesity and db/db mice that develop obesity spontaneously due to mutation in the leptin receptor (LepR). Intravenous or intraperitoneal administration of exogenous ORM decreased food intake in C57BL/6, HFD, and leptin-deficient ob/ob mice, which was absent in db/db mice and was significantly reduced in mice with arcuate nucleus (ARC) LepR knockdown, whereas enforced expression of ORM1 in ARC significantly decreased food intake, body weight, and serum insulin level. Furthermore, we found that ORM is able to bind directly to LepR and activate the receptor-mediated JAK2-STAT3 signaling in hypothalamus tissue and GT1-7 cells, which was derived from hypothalamic tumor. These data indicated that ORM could function through LepR to regulate food intake and energy homeostasis in response to nutrition status. Modulating the expression of ORM is a novel strategy for the management of obesity and related metabolic disorders.

    Sarcoptic mange is a contagious skin disease caused by Sarcoptes scabiei, affecting both domestic and wild mammals, including the Iberian ibex (Capra pyrenaica), a medium-sized mountain ungulate almost endemic to the Iberian Peninsula. Acute phase proteins (APPs) could be an indicator of sarcoptic mange disease and severity in Iberian ibex. Serum samples from 131 healthy and sarcoptic mange-affected Iberian ibexes were collected from 2005 to 2012 in Sierra Nevada Natural Space in southern Spain. Serum alpha-1-acid glycoprotein (AGP), serum amyloid A (SAA) and haptoglobin (Hp) concentrations were quantified, and statistically significant differences according to sarcoptic mange disease and severity were assessed. Both AGP and SAA were significantly higher in the sarcoptic mange-affected ibexes than in the healthy ones as well as in the severely affected ibexes as compared to those with less than 50 % of the body surface affected. For the first time, changes in APP are reported in relation to sarcoptic mange in Iberian ibex. It is also reported for the first time that the intensity of APP increase depends on the severity of sarcoptic mange, which could be related with the pathological secondary amyloidosis, leading to organ dysfunction in severely mange-affected animals. Species and population differences in the increase of APP in response to sarcoptic mange could indicate individual and population differences in the immune capability of each population to deal with mange, population prevalence and mortality being the last indicators of such sensitivity.

    Molecular hydrogen (H2 ) has been proven to be an effective agent that can cure multiple organ diseases by reducing oxidative stress. Although the protective effect of hydrogen on acute pancreatitis (AP) has been confirmed, its molecular mechanism is still unclear. In this article, we aimed to investigate the changes in pancreatic cell protein expression associated with the protective effect of H2 against AP and attempted to uncover the molecular mechanism underlying this process. A proteomic analysis identified 73 differentially expressed proteins and generated the protein-protein interaction networks of these proteins. The results triggered our interest in mitogen-activated protein kinase (MAPK) and heat shock cognate 71 kDa protein (Hsc70). The subsequent in vitro experiments showed that H2 treatment inhibited the phosphorylation of extracellular signal-regulated kinase (ERK), c-jun N-terminal kinase (JNK), and p38 MAPK, and activated NF-κB and the expression of tumor necrosis factor α and interleukin-1β, while simultaneously preventing the translocation of phospho-ERK, phospho-JNK, and phospho-p38 from the cytoplasm to the nucleus. Furthermore, Hsc70 expression was upregulated by H2 administration. The animal experimental results were consistent with those of the in vitro experiments. In conclusion, H2 treatment can ameliorate the inflammatory response and reduce the expression of inflammatory mediators during the early phase of AP by inhibiting the MAPK pathways and increasing Hsc70 expression.

    Major depressive disorder is a highly prevalent and debilitating condition in youth, so developing efficient treatments is a priority for mental health professionals. Psychotherapy (i.e., cognitive behavioral therapy/CBT), pharmacotherapy (i.e., SSRI medication), and their combination have been shown to be effective in treating youth depression; however, the results are still mixed and there are few studies engaging multi-level analyses (i.e., subjective, cognitive, and biological). Therefore, the aims of this randomized control study (RCT) were both theoretical - integrating psychological and biological markers of depression in a multi-level outcome analysis - and practical - testing the generalizability of previous results on depressed Romanian youth population. Eighty-eight (N=88) depressed Romanian youths were randomly allocated to one of the three treatment arms: group Rational Emotive Behavior Therapy (REBT)/CBT (i.e., a form of CBT), pharmacotherapy (i.e., sertraline), and group REBT/CBT plus pharmacotherapy. The results showed that all outcomes (i.e., subjective, cognitive, and biological) significantly change from pre to post-treatment under all treatment conditions at a similar rate and there were no significant differences among conditions at post-test. In case of categorical analysis of the clinical response rate, we found a non-significant trend favoring group REBT/CBT therapy. Results of analyses concerning outcome interrelations are discussed.

    Summary Objectives Carotid Body Tumor (CBT) is a rare lesion of the neuroendocrine system but it is the most common form of head and neck paraganglioma (PGL). Our objective is to discuss the optimal management of these lesions to provide the best outcome of patients treated by surgical resection. Patients and Methods A retrospective evaluation was obtained by review of the records of 20 patients with 26 CBT treated at our institution between 2000 and 2012. Primary tumor characteristics, diagnostic protocols, surgical treatment, short and long-term outcomes were collected and analyzed. Results A total of 26 CBTs resections were performed on 20 patients; the age range was 21–89 years. There was a female prevalence (14 women-80% and 6 men-20%). Familial cases occurred in 6 patients (30%); of these, 3 patients had bilateral lesions and 1 patient multiple paragangliomas. In all cases no lymph node metastasis was found. All lesions were grouped into three groups according to the latero-lateral diameter: Group I < 3 cm; Group II 3<>5cm; Group III >5cm. All patients were managed by surgical resection of the CBT. There were no operative deaths. Overall we found transitory neurological impairment in 15,3% and permanent neurological deficit in 7,6% of cases. No complications occurred in all resections of Group I tumors. In Group II only 1 resection was followed by dysphonia by recurrent nerve palsy (after vagal nerve en-bloc resection). In Group III only 1 resection was followed by permanent vagus nerve palsy. Conclusions Surgical removal of the tumor is the only treatment that can ensure a complete eradication of the disease. Family screening is of great importance in patients with hereditary forms. Careful preoperative planning of surgical procedure by integrated diagnostic imaging and a full mastery of the surgical technique can minimize the risk of the most common postoperative complications. Lifelong follow-up is mandatory to make early diagnosis of recurrent disease

    Full appreciation of the effectiveness of cognitive behavioral therapy (CBT) requires both effect size data and individual rates of positive response. Response rates are particularly helpful for clinicians when choosing among treatment options. However, systematic reviews on cross-study response rates have not been conducted, possibly due to the absence of a standardized metric for calculating response rates. We conducted a systematic review of the treatment outcome literature to determine overall response rates to CBT for anxiety disorders and whether current methods of defining treatment response influence overall response rates. Our database search (2000-2014) resulted in 87 studies that reported response rates and included at least one CBT condition. Results showed that overall treatment response rates across anxiety disorders averaged 49.5% at post-treatment and 53.6% at follow-up. Response rates varied significantly as a function of the properties used to define them. Measures that incorporated more than one criterion, the combination of a reliable change index with a clinical cutoff (a clinically significant change), and intent-to-treat samples yielded lower response rates at post-treatment. Blinded independent assessors yielded higher response rates than unblinded assessors. Based on previous empirical and theoretical work, we recommend that future studies use a clinically significant change index, in an intent-to-treat analysis (using a mixed-model approach), reflecting multiple modalities, and assessed by independent blinded assessors. Our results indicate that such measures are likely to reduce response rates, but may result in a less biased and more accurate representation of improvement and achievement of normative functioning.

    Dasatinib is a second generation tyrosine kinase inhibitor, with activity in imatinib resistant Ph-positive ALL.We have treated 34 patients with relapsed Philadelphia chromosome positive acute lymphoblastic leukemia(ALL) (n519) or lymphoid blast phase of chronic myelogenous leukemia (CML-LB) (n515) with the combination of dasatinib and the hyper CVAD regimen. Prior regimens included hyper CVAD plus imatinib(n511, 4 had transplant in first CR), other combination chemotherapy (n512), monotherapy with kinase inhibitors other than dasatinib (n59), and investigational agents (n52). Pretreatment ABL mutations were noted in 10 patients. The overall response rate was 91%, with 24 patients (71%) achieving complete response(CR), and 7(21%) CR with incomplete platelet recovery (CRp). Two patients died during induction and one had progressive disease. Twenty-six patients (84%) achieved complete cytogenetic remission after one cycle of therapy. Overall, 13 patients (42%) achieved complete molecular response, and 11 patients (35%) had major molecular response (BCR-ABL/ABL<0.1%). Nine patients proceeded to allogeneic transplantation.Grades 3 and 4 toxicities included hemorrhage, pleural and pericardial effusions and infections. The median follow-up for patients with CML-LB is 37.5 months (range, 7–70 months) with a 3-year overall survival of 70%;68% remained in CR at 3 years. For ALL patients, the median follow-up is 52 months (range, 45–59 months)with a 3-year survival of 26%; 30% remain in CR at 3 years. The combination of Hyper CVAD regimen with dasatinib is effective in patients with relapsed Ph-positive ALL and CML-LB. PMID:24779033

    The degree of methylation and cyclization of bacteria-derived branched glycerol dialkyl glycerol tetraether (GDGT) membrane lipids in soils depends on temperature and soil pH. Expressed in the methylation index of branched tetraethers (MBT) and cyclization ratio of branched tetraethers (CBT), these relationships are used to reconstruct past annual mean air temperature (MAT) based on the distribution of branched GDGTs in ancient sediments; the MBT-CBT proxy. Although it was shown that the best correlation of this proxy is with annual MAT, it remains unknown whether a seasonal bias in temperature reconstructions could occur, such as towards a seasonal period of 'optimal growth' of the, as yet, unidentified soil bacteria which produce branched GDGTs. To investigate this possibility, soils were sampled from eight different plots in the USA (Minnesota and Ohio), The Netherlands (Texel) and the UK (Devon) in time series over 1 year and analyzed for their branched GDGT content. Further analyses of the branched GDGTs present as core lipids (CLs; the presumed fossil pool) and intact polar lipids (IPLs; the presumed extant pool) were undertaken for two of the investigated soil plots. The amount of IPL-derived branched GDGTs is low relative to the branched GDGT CLs, i.e. only 6-9% of the total branched GDGT pool. In all soils, no clear change was apparent in the distribution of branched GDGT lipids (either core or IPL-derived) with seasonal temperature change; the MBT-CBT temperature proxy gave similar temperature estimates year-round, which generally matched the mean annual soil temperature. In addition to a lack of coherent changes in relative distributions, concentrations of the branched GDGTs did not show clear changes over the seasons. For IPL-derived GDGTs these results suggest that their turnover time in soils is in the order of 1 year or more. Thus, our study does not provide evidence for seasonal effects on the distribution of branched GDGTs in soils, at least at mid

    Several trials have demonstrated the efficacy of online cognitive behavioral therapy (CBT) for insomnia. However, few studies have examined putative mechanisms of change based on the cognitive model of insomnia. Identification of modifiable mechanisms by which the treatment works may guide efforts to further improve the efficacy of insomnia treatment. The current study therefore has two aims: (1) to replicate the finding that online CBT is effective for insomnia and (2) to test putative mechanism of change (i.e., safety behaviors and dysfunctional beliefs). Accordingly, we conducted a randomized controlled trial in which individuals with insomnia were randomized to either online CBT for insomnia (n = 36) or a waiting-list control group (n = 27). Baseline and posttest assessments included questionnaires assessing insomnia severity, safety behaviors, dysfunctional beliefs, anxiety and depression, and a sleep diary. Three- and six-month assessments were administered to the CBT group only. Results show moderate to large statistically significant effects of the online treatment compared to the waiting list on insomnia severity, sleep measures, sleep safety behaviors, and dysfunctional beliefs. Furthermore, dysfunctional beliefs and safety behaviors mediated the effects of treatment on insomnia severity and sleep efficiency. Together, these findings corroborate the efficacy of online CBT for insomnia, and suggest that these effects were produced by changing maladaptive beliefs, as well as safety behaviors. Treatment protocols for insomnia may specifically be enhanced by more focused attention on the comprehensive fading of sleep safety behaviors, for instance through behavioral experiments.

    Purpose: To report the acute toxicity profile and compliance from a randomized Phase III trial comparing accelerated radiotherapy (AR) with accelerated radiotherapy plus carbogen and nicotinamide (ARCON) in laryngeal cancer. Methods and Materials: From April 2001 to February 2008, 345 patients with cT2-4 squamous cell laryngeal cancer were randomized to AR (n = 174) and ARCON (n = 171). Acute toxicity was scored weekly until Week 8 and every 2-4 weeks thereafter. Compliance to carbogen and nicotinamide was reported. Results: Between both treatment arms (AR vs. ARCON) no statistically significant difference was observed for incidence of acute skin reactions (moist desquamation: 56% vs. 58%, p = 0.80), acute mucosal reactions (confluent mucositis: 79% vs. 85%, p = 0.14), and symptoms related to acute mucositis (severe pain on swallowing: 53% vs. 58%, p = 0.37; nasogastric tube feeding: 28% vs. 28%, p = 0.98; narcotic medicines required: 58% vs. 58%, p = 0.97). There was a statistically significant difference in median duration of confluent mucositis in favor of AR (2.0 vs 3.0 weeks, p = 0.01). There was full compliance with carbogen breathing and nicotinamide in 86% and 80% of the patients, with discontinuation in 6% and 12%, respectively. Adjustment of antiemesis prophylaxis was needed in 42% of patients. Conclusion: With the exception of a slight increase in median duration of acute confluent mucositis, the present data reveal a similar acute toxicity profile between both regimens and a good compliance with ARCON for clinical stage T2-4 laryngeal cancers. Treatment outcome and late morbidity will determine the real therapeutic benefit.

    The acute phase of ischemic stroke patients are often treated with both Chinese patent medicine:and western medicine therapies in clinical practice. This research included 27,678 cases of the acute phase of ischemic stroke came from 14 3A level hospitals. We collected data from patients with ischemic stroke who used both Chinese patent medicine and western medicine and were hopitalized within 14 days from hospital information system (HIS). Constructing complex network of Chinese patent medicine and western medicine were found to show scale-free network. Hierarchical structure of the core algorithm was used to analyze the characteristics of combined core Chinese patent medicine and western medicine in admission condition of "acute", "critically", and "general" of ischemic stroke acute phase patient within one day, 2-3 days, 4-7 days and 8-14 days. We found that the core Chinese patent medicine mainly used for activate blood and resolve stasis medicine, and phlegm eliminating brain refreshing medicine in all kinds of patients, but the phlegm eliminating brain refreshing medicine were used to reduce with time elapsing. The core western medicine mainly used for anti-platelet medicine, improve circulation medicine, neuroprotective medicine, anticoagulants medicine and dehydration medicine. The dehydration medicine as the core western medicine for critically patients within 14 days, but the patients for general admission as core western medicine within 3 days. The neuroprotective medicine was used to decreases after 7 days in hospital. Combination of Chinese patent medicine and western medicine were mainly for neuroprotective medicine + activate blood and resolve stasis medicine, and anti-platelet medicine + activate blood and resolve stasis medicine, and improve circulation medicine + activate blood and resolve stasis medicine. The phlegm eliminating brain refreshing medicine was mainly combined with neuroprotective medicine by urgent and general admission condition

    In most of the 129 patients with a recent stroke by cerebral hemorrhage or infarction a note-worthy acute-phase response was found, as demonstrated by important quantitative alterations of blood levels of several acute-phase proteins (APP). These alterations were different in patients with cerebral hemorrhage as compared to those with cerebral infarction. The alterations due to cerebral infarction were not different according to the site of the infarction in brain, i.e. in the brain territories irrigated by the carotid artery system or by the basilar artery system. The APP alterations do not depend on the sex of patients or on the time elapsed from stroke-onset to blood collection.

    Among the various systemic reactions against infection or injury, the acute phase response is the cascade of reaction and mostly coordinated by cytokines-mediated acute phase proteins (APPs) production. Since APPs are sensitive innate immune molecules, they are useful for early detection of inflammation in bovines and believed to be better discriminators than routine hematological parameters. Therefore, the possibility of using APPs as a diagnostic and prognostic marker of inflammation in major bovine health disorders including postpartum uterine infection has been explored by many workers. In this review, we discussed specifically importance of postpartum uterine infection, the role of energy balance in uterine infections and potential of APPs as a predictor of postpartum uterine infections during the transition period and its regulatory mechanism in dairy cattle.

    Curcumin and capsaicin are dietary xenobiotics with well-documented anti-inflammatory properties. Previously, the beneficial effect of these spice principles in lowering chronic inflammation was demonstrated using a rat experimental model for arthritis. The extent of lowering of arthritic index by the spice principles was associated with a significant shift in macrophage function favoring the reduction of pro-inflammatory molecules such as reactive oxygen species and production and release of anti-inflammatory metabolites of arachidonic acid. Beyond the cellular effects on macrophage function, oral administration of curcumin and capsaicin caused alterations in serum protein profiles of rats injected with adjuvant to develop arthritis. Specifically, a 72 kDa acidic glycoprotein, GpA72, which was elevated in pre-arthritic rats, was significantly lowered by feeding either curcumin or capsaicin to the rats. Employing the tandem mass spectrometric approach for direct sequencing of peptides, here we report the identification of GpA72 as T-kininogen I also known as Thiostatin. Since T-kininogen I is an early acute-phase protein, we additionally tested the efficiency of curcumin and capsaicin to mediate the inflammatory response in an acute phase model. The results demonstrate that curcumin and capsaicin lower the acute-phase inflammatory response, the molecular mechanism for which is, in part, mediated by pathways associated with the lowering of T-kininogen I.

    Elevated plasma or serum levels of thrombomodulin (TM), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin have been reported in several diseases. However, plasma or serum levels of TM, ICAM-1, VCAM-1, and E-selectin have not been investigated in the acute phase of Plasmodium vivax malaria. Serum TM, ICAM-1, VCAM-1, E-selectin, and creatinine levels were determined in six Japanese patients in the acute phase of vivax malaria and in seven healthy Japanese controls. Parasitemias of the peripheral blood were < 0.1% in five patients and 0.8% in one patient. The patients' mean +/- SD serum levels of TM, ICAM-1, VCAM-1, and E-selectin were 5.7 +/- 1.3 Fujirebio units/ml, 709 +/- 397 ng/ml, 2,112 +/- 782 ng/ml, and 99 +/- 28 ng/ml, respectively, and all were significantly greater than those in the controls (TM; P < 0.005, ICAM-1; P < 0.025, VCAM-1; P < 0.005, E-selectin; P < 0.025). However, no significant difference was identified between patients and controls for serum creatinine values. The serum levels of TM and VCAM-1 were not related to parasitemia. The elevation of serum TM levels suggests that endothelial cell damage occurs in the acute phase of vivax malaria.

    This preliminary randomized controlled trial (RCT) examines the feasibility of dismantling cognitive behavioral therapy (CBT) for childhood anxiety disorders. Fourteen children (10 girls) ages 7 to 14 (m = 10.2) with social phobia, generalized anxiety disorder, separation anxiety disorder, or panic disorder were randomized to receive 6 sessions of either a) the pre-exposure anxiety management strategies presented in traditional CBT, or b) parent-coached exposure therapy. The sample was selected from a treatment seeking population and is representative of children in clinical settings. Examination of fidelity ratings, dropouts, and satisfaction ratings indicated that the interventions were distinguishable, safe, and tolerable. The overall sample improved significantly with pre-post effect sizes generally in the large range for both conditions. Between-group effect sizes indicating greater improvement with parent-coached exposure therapy were moderate or large for ten of 12 variables (i.e., 0.53 to 1.52). Re-evaluation after three months of open treatment suggested that the intervention emphasizing exposure early maintained its superiority while requiring fewer appointments. PMID:26275761

    Performance anxiety, or stage fright, is anxiety aroused about potential mishaps in performance that expose feared inadequacies before an audience and which evoke feelings of embarrassment and humilation. For affected musicians, performance anxiety can be emotionally devastating, as their career choice in music may be terminated or severely compromised. This paper focuses on the cognitive and psychodynamic literature about music performance anxiety, with the emphasis that for treatment "one size does not fit all." It reviews the factors underlying performance anxiety and those factors which can exacerbate the condition in musicians. The two major clinical treatment modalities within contemporary psychology, cognitive behavior therapy (CBT) and psychodynamic treatments, are reviewed. While there are more empirical studies of CBT in various populations in the literature, until recently there was an indifference to empirical research by psychodynamic investigators. However, meta-analyses show strong efficacy for psychodynamic psychotherapy (in various disorders, not specifically music performance anxiety), but also that the benefits of psychodynamic psychotherapy may endure longer and increase with time.

    This study examined improvement in emotion regulation throughout Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) and the degree to which improvement in emotion regulation predicted improvement in symptoms. Traumatized children, 7-12 years (69.9% female), received TF-CBT. Data from 4 time periods were used: pre-assessment (n=107), pre-treatment (n=78), post-treatment (n=58), and 6-month follow-up (n=44). Questionnaires measured emotion regulation in the form of inhibition and dysregulation (Children's Emotion Management Scales) and lability/negativity and emotion regulation skill (Emotion Regulation Checklist), as well as child-reported (Trauma Symptom Checklist for Children) and parent-reported (Trauma Symptom Checklist for Young Children) posttraumatic stress, and internalizing and externalizing problems (Child Behaviuor Checklist). To the extent that children's dysregulation and lability/negativity improved, their parents reported fewer symptoms following therapy. Improvements in inhibition best predicted improvements in child-reported posttraumatic stress (PTS) during clinical services, but change in dysregulation and lability/negativity best predicted improvement in child-reported PTS symptoms at 6-month follow-up. Moreover, statistically significant improvements of small effect size were found following therapy, for inhibition, dysregulation, and lability/negativity, but not emotion regulation skill. These findings suggest that emotion regulation is a worthy target of intervention and that improvements in emotion regulation can be made. Suggestions for future research are discussed.

    This article describes (a) a web-based course for substance abuse counselors on Cognitive-Behavioral Therapy (CBT), and (b) the evaluation of a prototype module from the web-based course to determine the feasibility of the e-learning program for a community-based counselor audience. The course is part of a unique study that trains counselor-supervisor teams to increase the transfer of learned skills to the agency. Following curriculum design, we sought counselor reactions to the prototype module on strengths/limitations of the design, functionality, and effectiveness. Results showed that counselors learned new information, found this format effective compared to other training, and wanted to complete a full CBT web course. Counselors’ evaluation led content and technology changes: we add and segmented material aimed at the advanced, more theoretically-oriented counselor, and housed these topics behind an “advanced concept” graphics button; added 7 screens to accommodate text broken into smaller units; and increased the difficulty of the end-of-module quiz.

    Cognitive behaviour therapy (CBT), incorporating exposure and response prevention (ERP), has received strong empirical support for the treatment of paediatric OCD, and moreover, is considered the first line treatment of choice (Geller & March, 2012). However, despite the availability of effective treatments for this chronic and debilitating disorder, only a small proportion of youth receive these evidence-based approaches. The present study aimed to examine the effectiveness of an intensive ERP-based treatment for youth OCD, using a multiple baseline controlled design. Children and youth (N=10; aged 11-16 years) with a primary diagnosis of OCD were randomly assigned to a 1- or 2-week baseline monitoring condition followed by the intervention. The efficacy of the intensive treatment, involving 1 session psychoeducation, 2-sessions ERP plus e-therapy maintenance was examined across parent- child- and clinician-rated measures at post-treatment and 6-month follow-up. Overall, there were significant reductions across time on almost all measures (except self-report anxiety), and moreover, the majority of the sample (80%) were considered reliably improved, and meeting clinically significant change. At post-treatment, 60% were in remission of symptoms, and at 6-month follow-up this increased to 70%. These findings provide strong support for intensive, time-limited approaches to ERP-based CBT for children and youth with OCD.

    We report the results of a phase I study with four dose levels of bortezomib in combination with idarubicin. Eligible patients were newly diagnosed with acute myeloid leukemia (AML) age ≥60 years, or any adult with relapsed AML. Bortezomib was given twice weekly at 0.8, 1.0, or 1.2 mg/m(2) with once weekly idarubicin 10 mg/m(2) for four weeks. Twenty patients were treated: 13 newly diagnosed (median age 68, range 61-83) and 7 relapsed (median age 58, range 40-77). Prior myelodysplastic syndrome (MDS) was documented in 10/13 (77%) newly diagnosed and 1/7 (14%) relapsed patients; the three newly diagnosed patients without prior MDS had dyspoietic morphology. Two dose-limiting toxicities occurred at the initial dose level (bortezomib 0.8 mg/m(2) and idarubicin 10 mg/m(2)); idarubicin was reduced to 8 mg/m(2) without observing subsequent dose-limiting toxicities. The maximum tolerated dose in this study was bortezomib 1.2 mg/m(2) and idarubicin 8 mg/m(2). Common adverse events included: neutropenic fever, infections, constitutional symptoms, and gastrointestinal symptoms. No subjects experienced neurotoxicity. Most patients demonstrated hematologic response as evidenced by decreased circulating blasts. Four patients (20%) achieved complete remission. There was one treatment-related death. The combination of bortezomib and idarubicin in this mostly poor-risk, older AML group was well tolerated and did not result in high mortality. This trial was registered at www.clinicaltrials.gov as #NCT00382954.

    Purpose: To report on early results of a single-institution phase 2 trial of a 5-fraction, once-weekly radiation therapy regimen for patients undergoing breast-conserving surgery (BCS). Methods and Materials: Patients who underwent BCS for American Joint Committee on Cancer stage 0, I, or II breast cancer with negative surgical margins were eligible to receive whole breast radiation therapy to a dose of 30 Gy in 5 weekly fractions of 6 Gy with or without an additional boost. Elective nodal irradiation was not permitted. There were no restrictions on breast size or the use of cytotoxic chemotherapy for otherwise eligible patients. Patients were assessed at baseline, treatment completion, and at first posttreatment follow-up to assess acute toxicity (Common Terminology Criteria for Adverse Events, version 3.0) and quality of life (European Organization for Research and Treatment of Cancer QLQ-BR23). Results: Between January and September 2011, 42 eligible patients underwent weekly hypofractionated breast irradiation immediately following BCS (69.0%) or at the conclusion of cytotoxic chemotherapy (31.0%). The rates of grade ≥2 radiation-induced dermatitis, pain, fatigue, and breast edema were 19.0%, 11.9%, 9.5%, and 2.4%, respectively. Only 1 grade 3 toxicity—pain requiring a course of narcotic analgesics—was observed. One patient developed a superficial cellulitis (grade 2), which resolved with the use of oral antibiotics. Patient-reported moderate-to-major breast symptoms (pain, swelling, and skin problems), all decreased from baseline through 1 month, whereas breast sensitivity remained stable over the study period. Conclusions: The tolerance of weekly hypofractionated breast irradiation compares well with recent reports of daily hypofractionated whole-breast irradiation schedules. The regimen appears feasible and cost-effective. Additional follow-up with continued accrual is needed to assess late toxicity, cosmesis, and disease-specific outcomes.

    Background Mechanical ventilation at birth causes airway injury and lung inflammation in preterm sheep. Continuous positive airway pressure (CPAP) is being increasingly used clinically to transition preterm infants at birth. Objective To test if distending pressures will activate acute phase reactants and inflammatory changes in the airways of fetal, preterm lambs. Methods The head and chest of fetal lambs at 128±1 day GA were surgically exteriorized. With placental circulation intact, fetal lambs were then randomized to one of five 15 minute interventions: PEEP of 0, 4, 8, 12, or 16 cmH2O. Recruitment volumes were recorded. Fetal lambs remained on placental support for 30 min after the intervention. The twins of each 0 cmH2O animal served as controls. Fetal lung fluid (FLF), bronchoalveolar lavage fluid (BAL), right mainstem bronchi and peripheral lung tissue were evaluated for inflammation. Results Recruitment volume increased from 0.4±0.04 mL/kg at 4 cmH2O to 2.4±0.3 mL/kg at 16 cmH2O. The lambs were surfactant deficient, and all pressures were below the opening inflection pressure on pressure-volume curve. mRNA expression of early response genes and pro-inflammatory cytokines did not increase in airway tissue or lung tissue at any pressure compared to controls. FLF and BAL also did not have increases in early response proteins. No histologic changes or Egr-1 activation was present at the pressures used. Conclusion Distending pressures as high as 16 cmH2O did not recruit lung volume at birth and did not increase markers of injury in the lung or airways in non-breathing preterm fetal sheep.

    TAK-442 is an oral direct factor Xa inhibitor. We sought to determine the dose-dependent effect of TAK-442 on major bleeding when added to standard treatment in stabilised patients with acute coronary syndrome (ACS). In this phase II double-blind study, 2,753 ACS patients were randomised to TAK-442 or placebo in addition to usual care using a three-stage adaptive design. Patients were randomised to placebo in all stages, but doses of TAK-442 escalated from 10 mg BID, 20 mg twice-daily (BID), or 40 mg once-daily (QD) in stage 1; to 40 mg BID, 80 mg QD, or 80 mg BID in stage 2; and to 160 mg QD or 120 mg BID in stage 3. Study drug was started 36 hours after emergent treatment of ACS and within seven days of admission, and continued for 24 weeks. The primary endpoint was incidence of TIMI (thrombolysis in myocardial infarction) major bleeding. TIMI major bleeding incidence was low, but higher with the pooled TAK-442 doses than with placebo (17 [0.9%] vs 4 [0.5%]; p=0.47), although the difference was neither significant nor dose-dependent. However, a dose response was evident when using the modified ISTH scale. The incidence of cardiovascular events was similar among TAK-442 dose groups and placebo. When administered over a wide range of doses after an ACS event, TAK-442 treatment did not result in a dose-dependent increase in TIMI major bleeding, but increased bleeding was observed when a more sensitive bleeding scale was used. There was no evidence for efficacy.

The daily production of 11 plasma proteins was measured by electroimmunoassay and compared with the concentrations of the same proteins in the plasma of normal rats and of those with experimental inflammation. Hepatocytes from normal rats synthesized proteins in relative amounts which were similar to the relative proportions of the same proteins in the plasma of turpentine-injected animals. The pattern changed only slowly during 5 days in culture, but it did so profoundly either when the medium was devoid of dexamethasone or when human cytokines (from endotoxin-stimulated monocytes or unstimulated human squamous-carcinoma cell line COLO-16) were added. The cytokines consistently increased the synthesis of alpha 2-macroglobulin and fibrinogen and depressed that of albumin; variable increases in the synthesis of alpha 1-acute-phase globulin, alpha 1-acid glycoprotein, haptoglobin and alpha 1-proteinase inhibitor, and variable decreases in transferrin synthesis, were seen, whereas the synthesis of antithrombin III, alpha 1-macroglobulin and prothrombin remained virtually unaffected. The cytokine effects on protein synthesis required the presence of dexamethasone. The hepatocyte-stimulating activity derived from monocytes chromatographed on Sephadex G-100 corresponding to 30 000 Da, as opposed to the lymphocyte-activating factor, which was eluted as a molecule of approx. 15 000 Da. This suggests that both activities probably reside with distinct molecular species in the preparations of human cytokines. Images Fig. 3. PMID:6083778

    Acute phase proteins (APPs) and immune responses in pigs after experimental infection with H1N2 swine influenza virus (SwH1N2) were studied. Eight piglets were infected intranasally with SwH1N2. Four served as controls. Antibodies against swine influenza virus (SIV)s were measured by hemagglutination inhibition assay. The proliferation assay was used to measure influenza-specific cell-mediated response. Hematological parameters were measured on a hematology analyzer. C-reactive protein (CRP), haptoglobin (Hp), serum amyloid A (SAA) and pig major APP (Pig-MAP) concentrations in serum were measured using commercial ELISAs. Antibodies against SwH1N2 in the serum of infected pigs were detected from 7 dpi. SwH1N2-specific T-cell response was observed from 5 dpi. A significant drop in lymphocyte numbers and an increase in medium-sized cell (MID) counts with no accompanying leukopenia was observed in all infected pigs from 3 to 7 dpi. In infected pigs, concentrations of CRP, Hp and SAA increased significantly when the greatest amounts of virus were shed (from 1 to 3 dpi). The level of Pig-MAP remained unchanged during study. The significant positive correlation found between maximum concentrations of SAA in serum and lung scores, makes SAA a potentially useful indicator in experimental infection studies (e.g. vaccine efficiency investigations) or as a marker for disease severity, but to confirm this hypothesis more studies are needed.

    To increase understanding of the influence of blood pressure (BP) changes on functional outcome, we designed a multicenter, prospective, observational study involving patients with ischemic stroke. We included 1092 patients with ischemic stroke. BP was measured on admission and after 8, 16, 24, 32, 40, and 48 hours, and the averages of the readings were taken every 8 hours on days 3 to 7, at the day of discharge, and at 3 months. The main study variable was modified Rankin scale at 3 months. Systolic BPs >181 mm Hg at the emergency department and after 24 hours were associated with poor prognosis (odds ratio [OR]: 2.2, 95% CI: 1.2 to 4.2 and OR: 1.3, 95% CI: 1.1 to 2.3, respectively); systolic BP <136 mm Hg at the emergency department also determined worse prognosis at 3 months (OR: 1.3; 95% CI: 1.1 to 2.9). The influence of systolic BP changes in the first hours depended on patient age. In elder patients (>70 years), reductions in systolic BP determined a significant increase in the proportion of patients with worse prognosis. In patients >80 years of age, decreases in systolic BP >27.2 mm Hg determined a worse prognosis in patients with antihypertensive treatment at the emergency department (n=91) compared with those who did not receive treatment (n=106; OR: 21.7, 95% CI: 13.6 to 33.5 versus OR: 8.5, 95% CI: 3.2 to 19.6). In summary, the effect of BP modification during the acute phase of ischemic stroke on functional outcome is strongly dependent on age.

    Although primary infections with Toxoplasma gondii or herpes viruses during pregnancy are established teratogens, chronic maternal infections with these pathogens are considered far less serious. However, such chronic infections have been associated with neuropsychiatric disorders in the offspring. The risks of non-affective psychoses, including schizophrenia, in offspring associated with these exposures during pregnancy have not been completely defined. We used data from neonatal dried blood samples from 199 cases of non-affective psychosis and 525 matched controls (born 1975–1985). We measure immunoglobulin G antibodies directed at T. gondii, cytomegalovirus and herpes simplex virus type-1 and -2, as well as levels of nine acute phase proteins (APPs). We assessed the interaction between maternal antibodies and neonatal APP in terms of risk of non-affective psychosis. Among controls, maternal exposure to T. gondii or cytomegalovirus, but not to the other herpes viruses, was associated with significantly higher levels of neonatal APPs. Among cases, none of the maternal exposures were associated with any significant change in APPs. We observed increased RR for non-affective psychosis associated with maternal infection with T. gondii (odds ratio 2.1, 95% confidence interval 1.1–4.0) or cytomegalovirus (1.7, 0.9–3.3) only among neonates with low APP levels. These findings suggest that chronic maternal infection with T. gondii or cytomegalovirus affect neonatal markers of innate immunity. Deficient fetal immune responses in combination with maternal chronic infections may contribute to subsequent risk for psychosis. A greater understanding of the maternal–fetal immunological interplay may ultimately lead to preventive strategies toward neuropsychiatric disorders. PMID:25646591

    Anaplasma phagocytophilum immunodominant polymorphic major surface protein P44s have been hypothesized to go through antigenic variation, but the within-host dynamics of p44 expression has not been demonstrated. In the present study we investigated the composition and changes of p44 transcripts in the blood during the acute phase of well-defined laboratory A. phagocytophilum infections in naïve equine hosts. Three traveling waves of sequential population changeovers of the p44 transcript species were observed within a single peak of rickettsemia of less than 1 month. During the logarithmic increase, the rapid switch-off of the initial dominant transcript p44-18 occurred regardless of whether the bacterium was transmitted by ticks or by intravenous inoculation. Each of the subsequently dominant p44 transcript species was phylogenetically dissimilar from p44-18. Development of antibody to the hypervariable region of P44-18 during the rickettsemia suggests the suppression of dominance of immuno-cross-reactive p44 populations. When A. phagocytophilum was preincubated with plasma from the infected horse and then coincubated with HL-60 cells, the dominance of the p44-18 transcript was rapidly suppressed in vitro and most of the newly emerged p44 transcript species were previously undetected in this horse. This work provides experimental evidence of within-host p44 antigenic variation. Results suggest that the rapid and synchronized switch of expression is an intrinsic property of p44s reinitiated after transmission to naïve mammalian hosts and shaped upon exposure to immune plasma.

  9. Transfer of manualized CBT for social phobia into clinical practice (SOPHO-PRAX): a study protocol for a cluster-randomized controlled trial

    PubMed Central

    2012-01-01

    Background Cognitive-behavioral therapy (CBT) is generally known to be efficacious in the treatment of social phobia when applied in RCTs, namely when the treatment manual is based on the Clark-Wells approach. However, little is known about the efficacy of manualized treatments in routine clinical practice (Phase IV of psychotherapy research). The present study (SOPHO-PRAX) is a continuation of a large multicenter randomized clinical trial (SOPHO-NET) and analyzes the extent to which additional training practitioners in manualized procedures enhances treatment effect. Methods/design Thirty-six private practitioners will be included in three treatment centers and randomly designated to either training in manualized CBT or no specific training. The treatment effects of the therapies conducted by both groups of therapists will be compared. A total of 162 patients (n = 116 completers; n = 58 per condition) will be enrolled. Liebowitz Social Anxiety Scale (LSAS) will serve as primary outcome measure. Remission from social phobia is defined as LSAS total ≤30 points. Data will be collected at treatment begin, after 8, 15, and 25 sessions (50 min each), at treatment completion, as well at 6 and 12 months post-treatment. Discussion The present CBT trial combines elements of randomized controlled trials and naturalistic studies in an innovative way. It will directly inform about the incremental effects of procedures established in a controlled trial into clinical practice. Study results are relevant to healthcare decisions and policy. They may serve to improve quality of treatment, and shorten the time frame between the development and widespread dissemination of effective methods, thereby reducing health cost expenditure. The results of this study will not only inform about the degree to which the new methods lead to an improvement of treatment course and outcome, but also about whether the effects of routine psychotherapeutic treatment are comparable to those

    The MBT-CBT proxy for the reconstruction of paleotemperatures and past soil pH is based on the distribution of branched glycerol dialkyl glycerol tetraether (brGDGT) membrane lipids. The Methylation of Branched Tetraether (MBT) and the Cyclisation of Branched Tetraether (CBT) indices were developed to quantify these distributions, and significant empirical relations between these indices and annual mean air temperature (MAT) and/or soil pH were found in a large data set of soils. In this study, we extended this soil dataset to 278 globally distributed surface soils. Of these soils, 26% contains all nine brGDGTs, while in 63% of the soils the seven most common brGDGTs were detected, and the latter were selected for calibration purposes. This resulted in new transfer functions for the reconstruction of pH based on the CBT index: pH = 7.90-1.97 × CBT (r2 = 0.70; RMSE = 0.8; n = 176), as well as for MAT based on the CBT index and methylation index based on the seven most abundant GDGTs (defined as MBT‧): MAT = 0.81-5.67 × CBT + 31.0 × MBT‧ (r2 = 0.59; RMSE = 5.0 °C; n = 176). The new transfer function for MAT has a substantially lower correlation coefficient than the original equation (r2 = 0.77). To investigate possible improvement of the correlation, we used our extended global surface soil dataset to statistically derive the indices that best describe the relations of brGDGT composition with MAT and soil pH. These new indices, however, resulted in only a relatively minor increase in correlation coefficients, while they cannot be explained straightforwardly by physiological mechanisms. The large scatter in the calibration cannot be fully explained by local factors or by seasonality, but MAT for soils from arid regions are generally substantially (up to 20 °C) underestimated, suggesting that absolute brGDGT-based temperature records for these areas should be interpreted with caution. The applicability of the new MBT‧-CBT calibration function was tested

    Liver is the central organ of iron metabolism. During acute-phase-response (APR), serum iron concentration rapidly decreases. The current study aimed to compare expression and localization of iron transport protein ferroportin-1 (Fpn-1) and of other iron import proteins after experimental tissue damage induced by injecting turpentine oil in the hind limbs of rats and mice. Serum and spleen iron concentration decreased with an increase in total liver, cytoplasmic and nuclear iron concentration. In liver, mRNA amount of Fpn-1, Fpn-1a, Fpn-1b, HFE, hemojuvelin (HJV) and hephaestin (heph) genes showed a rapid decrease. Hepcidin, divalent metal transporter-1 (DMT-1), transferrin (Tf) and Tf-receptor-1 (TfR1), TfR-2 (TfR2) gene expression was increased. Western blot analysis of liver tissue lysate confirmed the changes observed at mRNA level. In spleen, a rapid decrease in gene expression of Fpn-1, Fpn-1a, Fpn-1b, DMT-1, Tf, TfR1 and TfR2, and an increase in hepcidin was observed. Immunohistochemistry of DMT-1 and TfR2 were mainly detected in the nucleus of rat liver and spleen, whereas TfR1 was clearly localized in the plasma membrane. Fpn-1 was mostly found in the nuclei of liver cells, whereas in spleen, the protein was mainly detected in the cell membrane. Western blot analysis of liver fractions confirmed immunohistochemical results. In livers of wild-type mice, gene expression of Fpn-1, Fpn-1a and Fpn-1b was downregulated, whereas hepcidin gene expression was increased. In contrast, these changes were less pronounced in IL-6ko-mice. Cytokine (IL-6, IL-1b and TNF-a) treatment of rat hepatocytes showed a downregulation of Fpn-1, Fpn-1a and Fpn-1b, and upregulation of hepcidin gene expression. Moreover, western blot analysis of cell lysate of IL-6-treated hepatocytes detected, as expected, an increase of a2-macroglobulin (positive acute-phase protein), whereas albumin (negative acute-phase protein) and Fpn-1 were downregulated. Our results demonstrate that liver

    We report a case of Cyberlindnera fabianii fungemia after umbilical cord blood transplantation (CBT). A 69-year-old woman was diagnosed as having mixed phenotype acute leukemia. The patient received CBT for primary refractory disease. After preconditioning chemotherapy, the patient's condition deteriorated, leading to acute respiratory failure from capillary leak syndrome and consequent admittance to the intensive care unit. The patient recovered temporarily following the administration of noninvasive positive pressure ventilation and continuous hemodiafiltration, but died of fungemia with the presence of yeast-like cells 15 days post-CBT. The yeast-like cells were analyzed by sequencing of the D1/D2 domain of the large subunit and the internal transcribed spacer domain, and were identified as C. fabianii. This case shows that molecular genetic-based methods may be effective for detecting undetermined invasive fungal infections in stem cell transplantation settings. PMID:26879198

    Growing evidence supports the efficacy of cord blood transplantation (CBT), and the number of CBTs is increasing. Numerous studies confirm the presence of a graft-versus-leukemia effect following CBT, and preliminary data suggests that double unit CBT may be associated with a decreased risk of relapse. We have observed a low relapse rate following CBT among patients with acute leukemias in morphologic CR at the time of myeloablative transplant. To further assess this observation we conducted a matched cohort analysis comparing relapse rates and outcomes for patients receiving CBTs versus patients receiving matched unrelated donor (MURD) and mismatched unrelated donor (MMURD) transplants at our center. Thirty-one consecutive CBT patients (ages 0.6–42, median 22) transplanted between April 2006 and June 2008 were compared to matched subjects selected on the basis of disease type and remission number, cytogenetic risk status, minimal residual disease status (MRD), time from diagnosis to first relapse (for patients beyond CR1), use of imatinib for CML and Philadelphia chromosome positive ALL patients, age, and date of transplant. With a median follow-up among surviving CBT patients of 21.1 months (range 6.6–32.6), there has been one relapse among cord patients versus eight relapses among MURD patients (p=0.018) and seven relapses among MMURD patients (p=0.019). Transplant related mortality (TRM) between cohorts is comparable. Though we have observed a high incidence of acute graft-versus-host disease (GVHD) following CBT, the incidence of National Institutes of Health (NIH) consensus criteria chronic GVHD has been low. These data support increased investigation of the use of CBT. PMID:19660726

    Relatively little is known about the application of cognitive behavioural therapy (CBT) to people with intellectual disabilities (ID). This review sought to synthesise available evidence on the effectiveness of CBT for anxiety or depression to assess the current level of evidence and make recommendations for future research. A comprehensive systematic literature search was conducted to identify qualitative and quantitative studies. Robust criteria were applied to select papers that were relevant to the review. Included papers were subject to quality appraisal. Eleven out of the 223 studies considered met our inclusion criteria and were included in the review in which CBT was used with participants with ID and anxiety (n=3), depression (n=4) or a mixed clinical presentation (n=4). There remains a paucity of evidence of effectiveness, however, the studies indicate that CBT is feasible and well-tolerated and may be effective in reducing symptoms of depression among adults with mild ID. Qualitative data reflect a positive perception of CBT amongst clients and carers. Further research is required to investigate the components of CBT, suitability for CBT, and requisite skills for CBT, which uses valid, sensitive and more holistic outcome measures.

    Study Objectives: Despite considerable evidence supporting cognitive behavioral therapy for insomnia (CBT-I) for chronic insomnia, it remains untested within the context of acute insomnia. This study examined the efficacy of a single session of CBT-I, with an accompanying self-help pamphlet, for individuals with acute insomnia. Design: A pragmatic parallel group randomized controlled trial. Setting: Community. Participants: Forty adults (mean age 32.9 ± 13.72 y) with Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) defined insomnia disorder, except a self-reported duration of less than 3 mo (i.e., acute insomnia), who reported no previous exposure to CBT-I and were not currently taking medication for sleep. Interventions: A single 60- to 70-min session of CBT-I (n = 20), with an accompanying self-help pamphlet, or wait list control group (n = 20). All subjects were offered a full individual course of CBT-I on completion of the study, regardless of group allocation. Measurements and Results: Subjects completed sleep diaries and the Insomnia Severity Index (ISI) pretreatment and 1 mo following treatment. There were no between-group differences on baseline ISI scores or subjective sleep continuity. The intervention group reported significantly lower ISI scores than controls (t(38) 2.24, P < 0.05) at follow-up. Further, using proposed ISI scores for identifying insomnia caseness (i.e., ≥ 10), 60% of those in the CBT-I group had remitted by 1 mo compared to 15% of those in the control group. Conclusions: This single session of cognitive behavioral therapy for insomnia (CBT-I) is sufficiently efficacious for a significant proportion of those with acute insomnia. The results are discussed in terms of integrating this brief form of CBT-I into the “stepped care” model of insomnia.

  16. Radiometric ligand binding assay for C-reactive protein. Complexed C-reactive protein is not detectable in acute phase serum.

    A radiometric ligand binding assay for human C-reactive protein (CRP) was established using pneumococcal C polysaccharide (CPS) coupled to magnetizable cellulose particles as the solid phase ligand. Competition for binding to the solid phase between 125I-CRP and unlabelled CRP permitted detection of 30 micrograms/l of CRP and the precise assay of concentrations up to 3000 micrograms/l. Identical results were obtained when the assay was used to quantitate isolated pure CRP and pure CRP added to normal human serum. However in vitro addition of known ligands for CRP to acute phase serum resulted in lowering of the apparent CRP concentration in this assay and addition of as little as 1 microgram/l of free CPS or 1 mg/l of lecithin was demonstrable in this way. A combination of the ligand binding assay and the standard electroimmunoassay for CRP was therefore used to test acute phase sera for the presence of CRP complexed in vitro. No evidence of complexed CRP was detected among sera containing between 1-319 mg/l of CRP from patients with Hodgkin's disease (10), rheumatoid arthritis (10), Crohn's disease (19) and various microbial infections (11), including six with subacute bacterial endocarditis. Since it is likely that CRP does form complexes with its ligands in the plasma these results suggest that complexed CRP is rapidly cleared from the circulation.

    Although L-asparaginase related hyperglycemia is well known adverse event, it is not studied whether the profile of this adverse event is affected by intensification of L-asparaginase administration. Here, we analyzed the profile of L-asparaginase related hyperglycemia in a 1,176 patients with pediatric acute lymphoblastic leukemia treated according to the Japan Association of Childhood Leukemia Study ALL-02 protocol using protracted L-asparaginase administration in maintenance phase. We determined that a total of 75 L-asparaginase related hyperglycemia events occurred in 69 patients. Although 17 events (17/1176, 1.4%) developed in induction phase, which was lower incidence than those (10-15%) in previous reports, 45 events developed during the maintenance phase with protracted L-asparaginase administration. Multivariate analysis showed that older age at onset (≥ 10 years) was a sole independent risk factor for L-asparaginase-related hyperglycemia (P<0.01), especially in maintenance phase. Contrary to the previous reports, obesity was not associated with L-asparaginase-related hyperglycemia. These findings suggest that protracted administration of L-asparaginase is the risk factor for hyperglycemia when treating adolescent and young adult acute lymphoblastic leukemia patients.

    Despite Cognitive Behavioural Therapy for Insomnia (CBT-I) being effective, barriers to adherence have been documented. Perceived partner alliance has been shown to influence adherence and treatment outcome across a range of other health conditions. The present study examined patients’ perceptions regarding the role of their partner in CBT-I and the impact of perceived partner alliance on treatment outcome. Twenty-one patients were interviewed, following CBT-I, to examine the areas where partners were thought to influence the process of CBT-I. The majority of statements made during interviews explicitly mentioned a partner’s influence (65%). Additionally, the production of more positive partner statements was associated with better treatment outcome (using the Insomnia Severity Index). The integration of perceived partner alliance, into CBT-I, is discussed. PMID:24527869

    A total of 314 patients exhibiting symptoms consistent with a viral disease provided, during the early stage of hospitalization, at least one specimen from a peripheral site (throat or stools or both) and a serum specimen in order to evaluate the neutralizing immunoglobulin M (IgM) antibody response in acute-phase serum in comparison with virus isolation for the rapid diagnosis of enterovirus (EV) infection. IgM antibodies were fractionated by ion-exchange chromatography and tested by seroneutralization against the various types of EV that have been recently circulating. A total of 189 patients (60%) were negative, and 21 (7%) were positive by both methods; in 51 patients (16%), a virus was isolated without IgM antibody response; 53 patients (17%) showed the opposite pattern. In all age groups except for children under 6 months, the frequency of positive results was higher with IgM serology than with virus isolation (27 and 22%, respectively). Apart from meningitis, for which isolation was more efficient, the other clinical conditions were associated with similar percentages of positivity by both methods. Regarding the 21 cases with positive results by the two techniques, the same serotype was detected in 9 cases and different serotypes were detected in 12, suggesting crossreactivities. Thus, IgM neutralizing antibody response on acute-phase serum appears to be of limited value in the rapid diagnosis of acute EV infection but may prove useful for the investigation of the wide range of chronic diseases associated with EV.

    The biosynthesis of rat alpha 1-inhibitor3, a negative acute-phase reactant specifically found in rodents, was studied in vitro in a cell-free translation system from rabbit reticulocytes, in rat hepatocyte primary cultures and in vivo by immunocytochemistry using normal and turpentine-injected rats. By sucrose-gradient centrifugation and subsequent translation of the fractionated RNA in vitro it was found that the mRNA coding for alpha 1-inhibitor3 exhibited a size of about 28S. For the alpha 1-inhibitor3 translated in vitro an apparent Mr of 155,000 was determined. A continuous decrease in the level of alpha 1-inhibitor3 in serum during experimental inflammation induced by turpentine injection was demonstrated by means of quantitative 'rocket' immunoelectrophoresis. This result agrees with the observation by immunocytochemistry of a drastic decrease in alpha 1-inhibitor3 levels in hepatocytes 24 h after turpentine injection. At that time alpha 1-inhibitor3 is mainly located in the Golgi apparatus, whereas it is also present in the membranes of the rough and smooth endoplasmic reticulum when normal liver is used. All hepatocytes, but no other hepatic cells, contain alpha 1-inhibitor3. When hepatocyte primary cultures were labelled with [35S]methionine and alpha 1-inhibitor3 was immunoprecipitated from the hepatocyte medium and the supernatant of homogenized cells, two different forms of alpha 1-inhibitor3 were found. The intracellular form of alpha 1-inhibitor3, with an apparent Mr of 173,000, is characterized by oligosaccharide side chains of the high-mannose type. The form of alpha 1-inhibitor3 in the medium exhibited an Mr of 186,000 and carried carbohydrate side chains of the complex type. After labelling hepatocytes with radioactive sugars, [3H]mannose was found in both forms of alpha 1-inhibitor3, whereas [3H]fucose and [3H]galactose were incorporated only into the form found in the medium.

    This phase III study evaluated the efficacy and safety of cariprazine, a dopamine D3 and D2 receptor partial agonist with preferential binding to D3 receptors, in patients with acute exacerbation of schizophrenia. Patients were randomized to 6-week double-blind treatment with placebo, cariprazine 3 to 6 mg/d, or cariprazine 6 to 9 mg/d. Primary and secondary efficacy: change from baseline to week 6 in Positive and Negative Syndrome Scale total and Clinical Global Impressions-Severity scores, respectively, analyzed using a mixed-effects model for repeated measures adjusting for multiple comparisons. Safety included treatment-emergent adverse events, clinical laboratory values, vital signs, electrocardiograms, ophthalmologic examination, Columbia-Suicide Severity Rating Scale, and extrapyramidal symptom scales. In the Safety Population (placebo, n = 147; cariprazine 3-6 mg/d, n = 151; cariprazine 6-9 mg/d, n = 148), 60.5% of patients completed the study. At week 6, statistically significant least squares mean differences in favor of cariprazine versus placebo were observed for Positive and Negative Syndrome Scale total score (3-6 mg/d: -6.8, P = 0.003; 6-9 mg/d: -9.9, P < 0.001) and Clinical Global Impressions-Severity (3-6 mg/d: -0.3, P = 0.012; 6-9 mg/d: -0.5, P < 0.001). Common treatment-emergent adverse events (≥5% and twice the rate of placebo) in both cariprazine groups were akathisia, extrapyramidal disorder, and tremor; most were mild to moderate in severity. Mean changes in metabolic parameters were generally small and similar between groups. Prolactin levels decreased in all groups. In conclusion, cariprazine 3 to 6 and 6 to 9 mg/d versus placebo demonstrated significant improvement on primary and secondary efficacy parameters. Cariprazine was generally well tolerated. These results suggest that cariprazine may be a new and effective treatment for schizophrenia. PMID:26075487

    At 14:46 on March 11, 2011, the Great East Japan Earthquake and tsunami occurred off the coast of Honshu, Japan. In the acute phase of this catastrophe, one of our teams was deployed as a Tokyo Disaster Medical Assistance Team (DMAT) to Kudan Kaikan in Tokyo, where the ceiling of a large hall had partially collapsed as the result of the earthquake, to conduct triage at the scene: 6 casualties were assigned to the red category (immediate), which included 1 case of cardiopulmonary arrest and 1 of flail chest; 8 casualties in the yellow category (delayed); and 22 casualties in the green category (minor). One severely injured person was transported to our hospital. Separately, our medical team was deployed to Miyagi 2 hours after the earthquake in our multipurpose medical vehicle as part of Japan DMAT (J-DMAT). We were the first DMAT from the metropolitan area to arrive, but we were unable to start medical relief activities because the information infrastructure had been destroyed and no specific information had yet reached the local headquarters. Early next morning, J-DMAT decided to support Sendai Medical Center and search and rescue efforts in the affected area and to establish a staging care unit at Camp Kasuminome of the Japan Self-Defense Force. Our team joined others to establish the staging care unit. Because information was still confused until day 3 of the disaster and we could not adequately grasp onsite medical needs, our J-DMAT decided to provide onsite support at Ishinomaki Red Cross Hospital, a disaster base hospital, and relay information about its needs to the local J-DMAT headquarters.

  6. Dependence of the cyclization of branched tetraethers (CBT) on soil moisture in the Chinese Loess Plateau and the adjacent areas: implications for palaeorainfall reconstructions

    Branched glycerol dialkyl glycerol tetraethers (bGDGTs) have been show promising for continental paleotemperature studies in loess-paleosol sequences (LPSs). Thus far, however, little is known about the effect of soil moisture on their distributions on the Chinese Loess Plateau (CLP). In this study, the relationships between environmental variables and the cyclization of bGDGTs (the so called CBT index) were investigated in a comprehensive set of surface soils in the CLP and its adjacent arid/semi-arid areas. We find that CBT correlates best with soil water content (SWC) or mean annual precipitation (MAP) for the total sample set. Particularly for the CLP soils, there is a significant positive relationship between CBT and MAP (CBT = -0.0021 · MAP + 1.7, n = 37, R2 = 0.87; MAP range: 210-680 mm). This indicates that CBT is mainly controlled by soil moisture in the alkalescent soils (pH > 7) in arid/semi-arid regions, where it is not sensitive to soil pH. Therefore, we suggest that CBT can potentially be used as a palaeorainfall proxy on the CLP. According to the preliminary CBT-MAP relationship for modern CLP soils, palaeorainfall history was reconstructed from three LPSs (Yuanbao, Lantian, and Mangshan) with published bGDGT data spanning the past 70 ka. The CBT-derived MAP records of the three sites consistently show precession-driven variations resembling the speleothem δ18O monsoon record, and are also in general accord with the fluctuations of the respective magnetic susceptibility (MS) record, supporting CBT as a reasonable proxy for palaeorainfall reconstruction in LPS studies. Moreover, the comparison of CBT-derived MAP and bGDGT-derived temperature may enable us to further assess the relative timing and magnitude of hydrological and thermal changes on the CLP, independent of chronology.

    The traditional treatment of venous thromboembolism (VTE) has been use of heparin and vitamin K antagonists (VKA), and although shown to be effective, they have numerous limitations. New oral anticoagulants (NOACs) including direct thrombin (factor IIa) inhibitors (dabigatran) and selective factor Xa inhibitors (rivaroxaban, apixaban and edoxaban) have emerged as promising alternatives with the potential to overcome the limitations of traditional treatments. Clinical trials have been performed with a view to making significant changes to the acute, long-term and extended treatment of VTE. Data are now available on the efficacy and safety, including bleeding rates, of the NOACs in comparison with VKA in the acute treatment and secondary prevention of VTE as well as in comparison with placebo extended VTE treatment. This review compares and contrasts the design and results of the Phase III trials of NOACs in VTE and discusses the implications of the NOACs in terms of treatment strategies in VTE patients.

    Clinical studies in adults and children with obsessive–compulsive disorder (OCD) have shown that d-cycloserine (DCS) can improve treatment response by enhancing fear extinction learning during exposure-based psychotherapy. Some have hypothesized that improved treatment response is a function of increased compliance and engagement in therapeutic homework tasks, a core component of behavioral treatment. The present study examined the relationship between DCS augmented cognitive-behavioral therapy (CBT) and homework compliance in a double-blind, placebo controlled trial with 30 youth with OCD. All children received 10 CBT sessions, the last seven of which included exposure and response prevention paired with DCS or placebo dosed 1 h before the session started. Results suggested that DCS augmented CBT did not predict improved homework compliance over the course of treatment, relative to the placebo augmented CBT group. However, when groups were collapsed, homework compliance was directly associated with treatment outcome. These findings suggest that while DCS may not increase homework compliance over time, more generally, homework compliance is an integral part of pediatric OCD treatment outcome. PMID:24999301

    After immersion in a foreign language, speakers often have difficulty retrieving native-language words and may experience a decrease in its proficiency, this phenomenon, in the non-pathological form, is known as first language attrition. Self-perception of this low native-language proficiency and apprehension occurring when speaking is expected and, may sometimes lead these people to a state of social anxiety and, in extreme forms, can involve the withholding of speech as a primitive tool for self-protection, linking them to selective mutism. We report an unusual case of selective mutism arising from first language attrition in an Italian girl after attending a two-year "German language school", who successfully responded to a paroxetine-cognitive behavioral treatment (CBT) combination treatment.

    Transdiagnostic cognitive-behavioral treatments for anxiety disorders have been gaining increased attention and empirical study in recent years. Despite this, all of the research on transdiagnostic anxiety treatments to date have either not used a control condition, or have relied on no-treatment or delayed-treatment controls, thus limiting inferences about comparative efficacy. The current study was a randomized clinical trial examining the efficacy of a 12-week transdiagnostic cognitive-behavioral group treatment in comparison to a 12-week comprehensive relaxation training program. Results from 87 treatment initiators suggested significant and statistically equivalent/non-inferior outcomes across conditions, although relaxation was associated with a greater rate of dropout despite no differences in treatment credibility. No evidence was found for any differential effects of transdiagnostic CBT for any primary or comorbid diagnoses. PMID:22697440

    Acute pancreatitis is an acute inflammation of the pancreas. Several classification systems have been used in the past but were considered unsatisfactory. A revised Atlanta classification of acute pancreatitis was published that assessed the clinical course and severity of disease; divided acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis; discerned an early phase (first week) from a late phase (after the first week); and focused on systemic inflammatory response syndrome and organ failure. This article focuses on the revised classification of acute pancreatitis, with emphasis on imaging features, particularly on newly-termed fluid collections and implications for the radiologist.

    Substantial attention and resources have been directed to improving outcomes of patients with critical illnesses, in particular sepsis, but all recent clinical trials testing various interventions or strategies have failed to detect a robust benefit on mortality. Acute heart failure is also a critical illness, and although the underlying etiologies differ, acute heart failure and sepsis are critical care illnesses that have a high mortality in which clinical trials have been difficult to conduct and have not yielded effective treatments. Both conditions represent a syndrome that is often difficult to define with a wide variation in patient characteristics, presentation, and standard management across institutions. Referring to past experiences and lessons learned in acute heart failure may be informative and help frame research in the area of sepsis. Academic heart failure investigators and industry have worked closely with regulators for many years to transition acute heart failure trials away from relying on dyspnea assessments and all-cause mortality as the primary measures of efficacy, and recent trials have been designed to assess novel clinical composite endpoints assessing organ dysfunction and mortality while still assessing all-cause mortality as a separate measure of safety. Applying the lessons learned in acute heart failure trials to severe sepsis and septic shock trials might be useful to advance the field. Novel endpoints beyond all-cause mortality should be considered for future sepsis trials. PMID:27034779

    In 2009, deep drilling at El'gygytgyn Crater Lake (Far East Russian Arctic) recovered sediments covering the past 3.6 Ma. These sediments provide the first terrestrial Arctic paleoclimate record spanning the Pliocene-Pleistocene from the largest and oldest unglaciated Arctic lake basin. Lake El'gygytgyn sediments thus offer a unique opportunity to examine high-latitude climate variability beyond the 100 Ka interval captured by Greenland ice core records. In this study we utilize an organic geochemical paleothermometer, the MBT/CBT Index based on branched glycerol dialkyl glycerol tetraethers (GDGTs; Weijers et al., 2007), to examine continental temperature variability during several key time intervals of interest. In particular, we focus on Marine Isotope Stages (MIS) 1-6, MIS 9-11, MIS 31 and during the earliest formation of lacustrine sediments in the impact basin in the middle Pliocene. Previous work on Lake El'gygytgyn sediments has identified MIS 11c and MIS 31 as "super" interglacials, which were characterized by significantly warmer temperatures than at present largely based on pollen spectra and modern analog analysis (Melles et al., 2012). Our results show that relative changes in MBT/CBT-derived temperatures display similar overall patterns of glacial-interglacial climate variability noted in temperature reconstructions from Lake El'gygytgyn (Melles et al., 2012) as well as Greenland ice core records, North Atlantic sea surface temperature records (e.g. Lawrence et al., 2010), and the global benthic δ18O stack (Lisiecki and Raymo, 2005). We demonstrate that MBT/CBT is a sensitive proxy for recording temperature variability at Lake El'gygytgyn. Interestingly, while pronounced warming is noted during interglacials, a number of abrupt and short-lived temperature reversals are also observed within these intervals, such as during MIS 5a and MIS 5e. Overall, we find that MBT/CBT temperatures closely track changes in local summer insolation at 67°N, in

    2011-01-01

    Background Several studies have showed that people with intellectual disabilities (ID) have suitable skills to undergo cognitive behavioural therapy (CBT). Case studies have reported successful use of cognitive behavioural therapy techniques (with adaptations) in people with ID. Modified cognitive behavioural therapy may be a feasible and effective approach for the treatment of depression, anxiety, and other mood disorders in ID. To date, two studies have reported group-based manaulised cognitive behavioural treatment programs for depression in people with mild ID. However, there is no individual manualised programme for anxiety or depression in people with intellectual disabilities. The aims of the study are to determine the feasibility of conducting a randomised controlled trial for CBT in people with ID. The data will inform the power calculation and other aspects of carrying out a definitive randomised controlled trial. Methods Thirty participants with mild ID will be allocated randomly to either CBT or treatment as usual (TAU). The CBT group will receive up to 20 hourly individual CBT over a period of 4 months. TAU is the standard treatment which is available to any adult with an intellectual disability who is referred to the intellectual disability service (including care management, community support, medical, nursing or social support). Beck Youth Inventories (Beck Anxiety Inventory & Beck Depression Inventory) will be administered at baseline; end of treatment (4 months) and at six months to evaluate the changes in depression and anxiety. Client satisfaction, quality of life and the health economics will be secondary outcomes. Discussion The broad outcome of the study will be to produce clear guidance for therapists to apply an established psychological intervention and identify how and whether it works with people with intellectual disabilities.

    Patients with sepsis or after major surgery have decreased plasma levels of the anticoagulant protein antithrombin. In such patients elevated levels of interleukin-6 (IL-6) are present and this interleukin is known to induce positive and negative acute phase responses. To investigate the possibility that antithrombin acts as a negative acute phase response-protein we performed studies on the human hepatoma cell line HepG2 in vitro and baboons in vivo. HepG2 cells were treated with recombinant human IL-6, IL-1beta, or combinations of the latter two, and tested for production of antithrombin, fibrinogen and prealbumin (transthyretin). This treatment resulted in a dose dependent increase in fibrinogen concentration (with a maximum effect of 2.8-2.9-fold) and a dose dependent decrease in prealbumin (with a maximum effect of 0.6-0.7-fold) and antithrombin concentrations (with a maximum effect of 0.6-0.8-fold). Simultaneous treatment of the HepG2 cells with IL-6 (1,000 pg/ml or 2,500 pg/ml) and IL-1beta (25 pg/ml), provided more extensively decreased prealbumin (0.8 and 0.6-fold, respectively) and antithrombin concentration (0.7 and 0.6-fold, respectively) compared to the single interleukin treatment at these concentrations. Baboons treated with 2 microg IL-6 x kg body-weight(-1) x day(-1) showed increased plasma CRP levels (59-fold, p <0.05) and decreased prealbumin (0.9-fold, p <0.05) and antithrombin (0.8-fold, p <0.05) plasma levels, without evidence for coagulation activation. Our results indicate that antithrombin acts as a negative acute phase protein, which may contribute to the decreased antithrombin plasma levels observed after major surgery or in sepsis.

    In healthy adults, transfusion of older stored red blood cells (RBCs) produces extravascular hemolysis and circulating non-transferrin-bound iron. In a prospective, observational study of critically ill children, we examined the effect of RBC storage duration on the extent of hemolysis by comparing laboratory measurements obtained before, and 4 hr after, RBC transfusion (N = 100) or saline/albumin infusion (N = 20). Transfusion of RBCs stored for longer than 4 weeks significantly increased plasma free hemoglobin (P < 0.05), indirect bilirubin (P < 0.05), serum iron (P < 0.001), and non-transferrin-bound iron (P < 0.01). However, days of storage duration poorly correlated (R(2) <0.10) with all measured indicators of hemolysis and inflammation. These results suggest that, in critically ill children, most effects of RBC storage duration on post-transfusion hemolysis are overwhelmed by recipient and/or donor factors. Nonetheless, we identified a subset of patients (N = 21) with evidence of considerable extravascular hemolysis (i.e., increased indirect bilirubin ≥0.4 mg/dL). In these patients, transfusion-associated hemolysis was accompanied by increases in circulating non-transferrin-bound iron and free hemoglobin and by an acute phase response, as assessed by an increase in median C-reactive protein levels of 21.2 mg/L (P < 0.05). In summary, RBC transfusions were associated with an acute phase response and both extravascular and intravascular hemolysis, which were independent of RBC storage duration. The 21% of transfusions that were associated with substantial hemolysis conferred an increased risk of inducing an acute phase response.

    To assess the initial and long-term results of 149 percutaneous transluminal coronary angioplasty (PTCA) procedures performed within 1 month of an acute myocardial infarction (AMI), 83 of them because of recurrent ischemia (post-infarction angina) after thrombolytic therapy with initial reperfusion success in the AMI (100 lesions attempted) (group I) and 66 PTCAs (69 lesions) performed during the acute phase of the AMI (group II). Mean age was 56 +/- 14 and 127 (85%) patients were male. Although successful dilation was obtained in 151 (89%) of the 169 attempted lesions, (96[96%] in group I vs 55[78%] in group II), clinical success was obtained in only 123 (82%) (76[92%] vs 64[77%] in both groups, respectively). Late occlusion occurred in 14 (9%) of the 151 lesions successfully dilated (6[6%] and 8[15%], respectively) and reinfarction was documented in 7 (5%) patients (5[5%] and 2[3%]). One patient in group I underwent coronary bypass surgery. There were 4 (3%) hospital deaths (1[1%] and 3[4%]) in group I and II, respectively). Event-free (no occurrence of death, AMI, coronary surgery, repeat PTCA or angina recurrence) survival rate was 76%, 73% and 67% in group I versus 62%, 57% and 40% in group II, at 1, 2 and 4 years respectively. During follow-up, 1 (1%) patient of the group I and 4 of the group II died. At last follow-up, 63 (78%) of the 81 patients alive vs 33 (67%) of the 59 patients in the group I and II respectively remained asymptomatic. In conclusion, in our experience elective PTCA performed in the subacute phase after an AMI provides better initial and long-term outcome than that performed in the acute phase. Therefore, the procedure would be delayed whenever possible.

    In chronic liver disease, high circulating interleukin (IL)-6 contrasts with a poor acute phase response. We evaluated the impact of liver and circulating IL-6-receptor (IL-6R) forms on IL-6 bioactivity in chronic liver disease. IL-6, soluble IL-6-receptor and sgp130 levels were assayed in plasma from 45 patients with alcoholic liver disease, 84 with hepatitis C virus (HCV) infection undergoing transjugular liver biopsies and 15 healthy subjects. IL-6R mRNA was quantified on liver extracts from 54 patients with alcoholic liver disease with or without cirrhosis and 18 HCV-infected patients. The effect of gp130–Fc on fibrinogen secretion induced by IL-6 trans-signalling was evaluated on hepatocyte cultures. Levels of plasma IL-6 and sgp130, but not soluble IL-6R, increased with the stage of chronic liver disease, and correlated significantly with disease severity. Alcoholic liver disease patients had higher plasma IL-6 levels than hepatitis C, but lower liver IL-6R expression. In alcoholic and HCV-related liver diseases, liver IL-6R expression decreased with advanced fibrosis stage. In vitro, on hepatocytes, gp130–Fc blunted the acute phase response while soluble IL-6R enhanced IL-6 stimulation. In advanced chronic liver disease, high plasma IL-6 is associated with low liver IL-6R expression. This situation enables high plasma sgp130 to act as a major negative regulator of liver IL-6 trans-signalling, as demonstrated functionally here on hepatocytes. This might explain the poor acute phase response induced by IL-6 in chronic liver disease. PMID:19438606

    Efficacy of conventional opioids can be limited by adverse events (AEs). TRV130 is a structurally novel biased ligand of the μ-opioid receptor that activates G protein signaling with little β-arrestin recruitment. In this phase 2, randomized, placebo- and active-controlled study, we investigated the efficacy and tolerability of TRV130 in acute pain after bunionectomy. We used an adaptive study design in which 144 patients experiencing moderate-to-severe acute pain after bunionectomy were randomized to receive double-blind TRV130, placebo, or morphine in a pilot phase. After pilot phase analysis, 195 patients were randomized to receive double-dummy TRV130 0.5, 1, 2, or 3 mg every 3 hours (q3h); placebo; or morphine 4 mg q4h intravenously. The primary end point was the time-weighted average change in numeric rating scale pain intensity over the 48-hour treatment period. Secondary end points included stopwatch and categorical assessments of pain relief. Safety and tolerability were also assessed. TRV130 2 and 3 mg q3h, and morphine 4 mg q4h produced statistically greater mean reductions in pain intensity than placebo over 48 hours (P < 0.005). TRV130 at 2 and 3 mg produced significantly greater categorical pain relief than morphine (P < 0.005) after the first dose, with meaningful pain relief occurring in under 5 minutes. TRV130 produced no serious AEs, with tolerability similar to morphine. These results demonstrate that TRV130 rapidly produces profound analgesia in moderate-to-severe acute pain, suggesting that G-protein-biased μ-opioid receptor activation is a promising target for development of novel analgesics.

    Objective Rupture of abdominal aortic aneurysm (AAA), a major cause of death in the aged population, is characterized by vascular inflammation and matrix degradation. Serum amyloid A (SAA), an acute phase reactant linked to inflammation and matrix metalloproteinase induction, correlates with aortic dimensions before aneurysm formation in humans. We investigated whether SAA deficiency in mice impacts AAA formation during angiotensin II (AngII) infusion. Approach and Results Plasma SAA increased ~60-fold in apoE−/− mice 24 hours after i.p. AngII injection (100 μg/kg; n = 4) and ~15-fold after chronic 28-day AngII infusion (1,000 ng/kg/min; n = 9). AAA incidence and severity after 28-day AngII infusion was significantly reduced in apoE−/− mice lacking both acute phase SAA isoforms (SAAKO; n = 20) compared to apoE−/− mice (SAAWT; n = 20) as assessed by in vivo ultrasound and ex vivo morphometric analyses, despite a significant increase in systolic blood pressure in SAAKO mice compared to SAAWT mice after AngII infusion. Atherosclerotic lesion area of the aortic arch was similar in SAAKO and SAAWT mice after 28-day AngII infusion. Immunostaining detected SAA in AAA tissues of AngII-infused SAAWT mice that co-localized with macrophages, elastin breaks, and enhanced matrix metalloproteinase (MMP) activity. MMP-2 activity was significantly lower in aortas of SAAKO mice compared to SAAWT mice after 10-day AngII infusion. Conclusion Lack of endogenous acute phase SAA protects against experimental AAA through a mechanism that may involve reduced MMP-2 activity. PMID:25745063

    Objective Development of an in vivo imaging method to assess lymphatic draining function in the K/B×N mouse model of inflammatory arthritis. Methods Indocyanine green (ICG), a near-infrared (NIR) fluorescent dye, was injected intradermally into the footpad of wild-type mice, the limb was illuminated with an 806 nm NIR laser, and the movement of ICG from the injection site to the draining popliteal lymph node (PLN) was recorded with a CCD camera. ICG-NIR images were analyzed to obtain 5 measures of lymphatic function across time. K/B×N arthritic mice and control non-arthritic littermates were imaged at one-month of age when acute joint inflammation commenced, and repeated at 3 months when joint inflammation became chronic. Lymphangiogenesis in PLNs was assessed by immunochemistry. Results ICG and its transport within lymphatic vessels were readily visualized and quantitative measures derived. During the acute phase of arthritis, the lymphatic vessels were dilated with increased ICG signal intensity and lymphatic pulses, and PLNs became fluorescent quickly. During the chronic phase, new lymphatic vessels were present near the foot. However, ICG appearance in lymphatic vessels was delayed. The size and area of PLN lymphatic sinuses progressively increased in the K/B×N mice. Conclusion ICG-NIR lymphatic imaging is a valuable method to assess the lymphatic draining function in mice with inflammatory arthritis. ICG-NIR imaging of K/B×N mice identified two distinct lymphatic phenotypes during the acute and chronic phase of inflammation. This technique can be used to assess new therapies for lymphatic disorders. PMID:20309866

    A woman had been followed since 1957 for acute phase Chagas disease. Parasitological and serological tests were positive, and treatment included benznidazole in 1974. Following treatment, parasitological test results were negative and conventional serology remained positive until 1994, with subsequent discordant results (1995-1997). The results became consistently negative since 1999. She had an indeterminate chronic form until 1974. Only two minor and transitory nonspecific alterations on electrocardiogram were noted, with the last nine records normal until June 2014. This case confirms the possibility of curing chronic disease and suggests the benefit of specific treatments for preventing long-term morbidity. PMID:26516979

    A 32-year-old woman with acute myeloid leukemia failed to achieve remission with two courses of induction chemotherapy, and she received cord blood transplantation (CBT) in a non-remission state, using an HLA-matched cord blood (CB) graft after a conditioning regimen of fludarabine (Flu) at 125 mg/m² + melphalan at 140 mg/m² + total body irradiation (TBI) at 4 Gy. Chimerism analysis of the bone marrow (BM) cells performed on day 21 after CBT revealed 99% of these cells to be the recipient type. We diagnosed the patient as having graft failure (GF), and then carried out a second CBT using an HLA-matched male CB graft on day 29 after the first CBT. The conditioning regimen (modified 'one-day'-based regimen) consisted of Flu at 30 mg/m² (3 days) + cyclophosphamide (CY) at 2 g/m² (1 day) + TBI 2 Gy. She achieved neutrophil engraftment on day 18. FISH analysis of BM cells on day 13 showed 96% to be of male origin. She has remained in complete remission for 18 months, to date, since the salvage CBT. This case suggests that salvage CBT following a modified 'one-day'-based regimen may preserve a strong graft versus leukemia effect.

    The objective of this study was to evaluate the efficacy, safety and tolerability of brexpiprazole versus placebo in adults with acute schizophrenia. This was a 6-week, multicenter, placebo-controlled double-blind phase 3 study. Patients with acute schizophrenia were randomized to brexpiprazole 1, 2 or 4 mg, or placebo (2:3:3:3) once daily. The primary endpoint was changed from baseline at week 6 in Positive and Negative Syndrome Scale (PANSS) total score; the key secondary endpoint was Clinical Global Impressions-Severity (CGI-S) at week 6. Brexpiprazole 4 mg showed statistically significant improvement versus placebo (treatment difference: -6.47, p=0.0022) for the primary endpoint. Improvement compared with placebo was also seen for the key secondary endpoint (treatment difference: -0.38, p=0.0015), and on multiple secondary efficacy outcomes. Brexpiprazole 1 and 2mg also showed numerical improvements versus placebo, although p>0.05. The most common treatment-emergent adverse events were headache, insomnia and agitation; incidences of akathisia were lower in the brexpiprazole treatment groups (4.2%-6.5%) versus placebo (7.1%). Brexpiprazole treatment was associated with moderate weight gain at week 6 (1.23-1.89 kg versus 0.35 kg for placebo); there were no clinically relevant changes in laboratory parameters and vital signs. In conclusion, brexpiprazole 4 mg is an efficacious and well-tolerated treatment for acute schizophrenia in adults. Clinical Trials.gov NCT01393613; BEACON trial.

    After ovulation, non-pregnant female giant pandas experience pseudopregnancy. During pseudopregnancy, non-pregnant females exhibit physiological and behavioral changes similar to pregnancy. Monitoring hormonal patterns that are usually different in pregnant mammals are not effective at determining pregnancy status in many animals that undergo pseudopregnancy, including the giant panda. Therefore, a physiological test to distinguish between pregnancy and pseudopregnancy in pandas has eluded scientists for decades. We examined other potential markers of pregnancy and found that activity of the acute phase protein ceruloplasmin increases in urine of giant pandas in response to pregnancy. Results indicate that in term pregnancies, levels of active urinary ceruloplasmin were elevated the first week of pregnancy and remain elevated until 20-24 days prior to parturition, while no increase was observed during the luteal phase in known pseudopregnancies. Active ceruloplasmin also increased during ultrasound-confirmed lost pregnancies; however, the pattern was different compared to term pregnancies, particularly during the late luteal phase. In four out of the five additional reproductive cycles included in the current study where females were bred but no birth occurred, active ceruloplasmin in urine increased during the luteal phase. Similar to the known lost pregnancies, the temporal pattern of change in urinary ceruloplasmin during the luteal phase deviated from the term pregnancies suggesting that these cycles may have also been lost pregnancies. Among giant pandas in captivity, it has been presumed that there is a high rate of pregnancy loss and our results are the first to provide evidence supporting this notion.

    Older patients with acute myeloid leukemia (AML) have worse rates of complete remission and shorter overall survival than younger patients. The epigenetic modifier CC-486 is an oral formulation of azacitidine with promising clinical activity in patients with AML in Phase I studies. The Phase III, randomized, double-blind, placebo-controlled QUAZAR AML Maintenance trial (CC-486-AML-001) examines CC-486 maintenance therapy (300 mg/day for 14 days of 28-day treatment cycles) for patients aged ≥55 years with AML in first complete remission. The primary end point is overall survival. Secondary end points include relapse-free survival, safety, health-related quality of life and healthcare resource utilization. This trial will investigate whether CC-486 maintenance can prolong remission and improve survival for older patients with AML.

    Abstract Efficacy and security of a plasmapheresis procedure in complex of treatment of nonbiliary acute pancreatitis in early phase of the disease were established, basing on the treatment results analysis in 48 patients. The plasmapheresis results were estimated in accordance to changes revealed in the intoxication leukocytic index (ILI), a general protein (GP) content, general calcium (GC) in the blood plasm and of the activated partial thrombin time (APTHT). Application of plasmapheresis in patients, suffering purulent pancreatitis in the enzymal phase, have guaranteed a staged reduction of ILI by (34.86 ± 1.27)%, the APTHT enhancement from (35.15 ± 0.37) to (52.01 ± 0.62) sec, a trustworthy lowering of the GP by (4.35 ± 0.02) g/L at average and of GC in a blood plasmby (10.45 ± 0.38)%.

    Purpose: To evaluate with a randomized clinical trial the possibility of treating the index quadrant with external intensity-modulated radiotherapy (IMRT) in a selected group of patients with early-stage breast cancer and to analyze the acute toxicity. Methods and Materials: From September 2005, a randomized Phase III clinical trial has been conducted to compare conventional (tangential field) fractionated whole breast treatment (Arm A) with accelerated partial breast irradiation plus intensity-modulated radiotherapy (Arm B). For intensity-modulated radiotherapy, the clinical target volume was drawn with a uniform 1-cm margin around the surgical clips in three dimensions. The ipsilateral and contralateral breast, ipsilateral and contralateral lung, heart, and spinal cord were contoured as organs at risk. All the regions of interest were contoured according to the International Commission on Radiation Units and Measurements reports 50 and 62 recommendations. Results: In September 2008, 259 patients were randomized and treated. The mean clinical target volume in Arm B was 44 cm{sup 3} and the mean planning target volume was 123 cm{sup 3}. The mean value of the ratio between the planning target volume and the ipsilateral breast volume was 21%. The rate of Grade 1 and Grade 2 acute skin toxicity was 22% and 19% in Arm A (Radiation Therapy Oncology Group scale), respectively. The tolerance in Arm B was excellent with only 5% Grade 1 and 0.8% Grade 2 acute skin toxicity. The planning constraints were fully satisfied in most patients. In a very few cases, this was not possible because of very unfavorable anatomy. Quality assurance procedures were performed according to our internal quality assurance protocol, with excellent results. Conclusion: In the present preliminary analysis, we have demonstrated that accelerated partial breast irradiation is feasible, with very low acute toxicity.

    This study examines how injury mechanisms and early neuroimaging and clinical measures impact white matter (WM) fractional anisotropy (FA), mean diffusivity (MD), and tract volumes in the chronic phase of traumatic brain injury (TBI) and how WM integrity in the chronic phase is associated with different outcome measures obtained at the same time. Diffusion tensor imaging (DTI) at 3 T was acquired more than 1 year after TBI in 49 moderate-to-severe-TBI survivors and 50 matched controls. DTI data were analyzed with tract-based spatial statistics and automated tractography. Moderate-to-severe TBI led to widespread FA decreases, MD increases, and tract volume reductions. In severe TBI and in acceleration/deceleration injuries, a specific FA loss was detected. A particular loss of FA was also present in the thalamus and the brainstem in all grades of diffuse axonal injury. Acute-phase Glasgow Coma Scale scores, number of microhemorrhages on T2*, lesion volume on fluid-attenuated inversion recovery, and duration of posttraumatic amnesia were associated with more widespread FA loss and MD increases in chronic TBI. Episodes of cerebral perfusion pressure <70 mmHg were specifically associated with reduced MD. Neither episodes of intracranial pressure >20 mmHg nor acute-phase Rotterdam CT scores were associated with WM changes. Glasgow Outcome Scale Extended scores and performance-based cognitive control functioning were associated with FA and MD changes, but self-reported cognitive control functioning was not. In conclusion, FA loss specifically reflects the primary injury severity and mechanism, whereas FA and MD changes are associated with objective measures of general and cognitive control functioning.

    The overall CD8 T cell response to human/simian immunodeficiency virus (HIV/SIV) targets a collection of discrete epitope specificities. Some of these epitope-specific CD8 T cells emerge in the weeks and months following infection and rapidly select for sequence variants, whereas other CD8 T cell responses develop during the chronic infection phase and rarely select for sequence variants. In this study, we tested the hypothesis that acute-phase CD8 T cell responses that do not rapidly select for escape variants are unable to control viral replication in vivo as well as those that do rapidly select for escape variants. We created a derivative of live attenuated SIV (SIVmac239Δnef) in which we ablated five epitopes that elicit early CD8 T cell responses and rapidly accumulate sequence variants in SIVmac239-infected Mauritian cynomolgus macaques (MCMs) that are homozygous for the M3 major histocompatibility complex (MHC) haplotype. This live attenuated SIV variant was called m3KOΔnef. Viremia was significantly higher in M3 homozygous MCMs infected with m3KOΔnef than in either MHC-mismatched MCMs infected with m3KOΔnef or MCMs infected with SIVmac239Δnef. Three CD8 T cell responses, including two that do not rapidly select for escape variants, predominated during early m3KOΔnef infection in the M3 homozygous MCMs, but these animals were unable to control viral replication. These results provide evidence that acute-phase CD8 T cell responses that have the potential to rapidly select for escape variants in the early phase of infection are needed to establish viral control in vivo.

    In recent years, combinations of pharmacological treatments have become common for the treatment of bipolar disorder type I (BP I); however, this practice is usually not evidence-based and rarely considers monotherapy drug regimen (MDR) as an option in the treatment of acute phases of BP I. Therefore, we evaluated comparative data of commonly prescribed MDRs for both manic and depressive phases of BP I. Medline, PsycINFO, EMBASE, the Cochrane Library, the ClinicalStudyResults.org and other data sources were searched from 1949 to March 2009 for placebo and active controlled randomized clinical trials (RCTs). Risk ratios (RRs) for response, remission, and discontinuation rates due to adverse events (AEs), lack of efficacy, or discontinuation due to any cause, and the number needed to treat or harm (NNT or NNH) were calculated for each medication individually and for all evaluable trials combined. The authors included 31 RCTs in the analyses comparing a MDR with placebo or with active treatment for acute mania, and 9 RCTs comparing a MDR with placebo or with active treatment for bipolar depression. According to the collected evidence, most of the MDRs when compared to placebo showed significant response and remission rates in acute mania. In the case of bipolar depression only quetiapine and, to a lesser extent, olanzapine showed efficacy as MDR. Overall, MDRs were well tolerated with low discontinuation rates due to any cause or AE, although AE profiles differed among treatments. We concluded that most MDRs were efficacious and safe in the treatment of manic episodes, but very few MDRs have demonstrated being efficacious for bipolar depressive episodes. PMID:20128953

    In habitually shod recreational runners, we studied the combined influence of footwear and stretch-shortening cycle (SSC) fatigue on treadmill running pattern, paying special attention to neuro-mechanical adjustments in the acute and 2-day delayed recovery periods. The SSC exercise consisted of a series of 25 sub-maximal rebounds on a sledge apparatus repeated until exhaustion. The acute and delayed functional fatigue effects were quantified in a maximal drop jump test. The neuro-mechanical adjustments to fatigue were examined during two submaximal treadmill run tests of 3 min performed either barefoot or with shoes on. Surface electromyographic (EMG) activities, tibial accelerations and kinematics of the right lower limb were recorded during the first and last 15 s of each run. The main result was that neuro-mechanical differences between the shod and barefoot running patterns, classically reported in the absence of fatigue, persisted in the fatigued state. However, in the delayed recovery phase, rearfoot eversion was found to significantly increase in the shod condition. This specific footwear effect is considered as a potential risk factor of overuse injuries in longer runs. Therefore, specific care should be addressed in the delayed recovery phase of SSC fatigue and the use of motion control shoes could be of interest.

    The aim of this study was to evaluate the concentration of acute phase proteins, milk production, and resumption of postpartum ovarian activity of clinically healthy dairy cows in a semi-extensive system with different Liver Functionality Index (LFI) values. The animals were divided into two groups: Low LFI (LLFI: -7 to -12; n: 10) and High LFI (HLFI: -7 to -4; n: 10). Animals with LLFI had lower paraoxonase activity and lower albumin concentration in the pre- and postpartum periods (P<0.05), higher non-esterified fatty acids prepartum (P<0.005), and higher haptoglobin concentration postpartum (P<0.01). The LLFI group showed lower resumption of ovarian activity until 44days postpartum (29%; P<0.05) than HLFI (86%). Milk production did not differ between groups. Therefore, this study suggests that the LFI is an important biomarker of synthesis of acute phase proteins and the first ovulation interval, and it can be used to improve the production and reproductive performance.

    Champedak (Artocarpus integer) lectin-M is a lectin with high specificity and affinity for the core-mannosyl residues of the N-linked oligosaccharides of glycoproteins. We have studied the interaction of the champedak seed lectin with human serum glycoproteins that were resolved by 2-dimensional (2-D) gel electrophoresis. The lectin demonstrated strong interaction with haptoglobin beta chain, orosomucoid, alpha1-antitrypsin, alpha2-HS glycoprotein, transferrin, hemopexin, alpha1B-glycoprotein, and the heavy chains of IgA, IgM and IgG of the human serum. With exceptions of the heavy chains of the immunoglobulins and alpha1B-glycoprotein, all the other lectin-M-probed glycopeptides are acute-phase proteins. The use of champedak lectin-M to probe for serum glycoproteins that were separated in a 2-D gel electrophoresis and Western blotting technique may be conveniently applied to analyse the acute-phase and humoral immune responses simultaneously. Subjecting human serum to immobilised-lectin-M affinity chromatography was able to isolate intact haptoglobin, alpha1-antitrypsin, alpha1B-glycoprotein, hemopexin and IgA.

    In habitually shod recreational runners, we studied the combined influence of footwear and stretch-shortening cycle (SSC) fatigue on treadmill running pattern, paying special attention to neuro-mechanical adjustments in the acute and 2-day delayed recovery periods. The SSC exercise consisted of a series of 25 sub-maximal rebounds on a sledge apparatus repeated until exhaustion. The acute and delayed functional fatigue effects were quantified in a maximal drop jump test. The neuro-mechanical adjustments to fatigue were examined during two submaximal treadmill run tests of 3 min performed either barefoot or with shoes on. Surface electromyographic (EMG) activities, tibial accelerations and kinematics of the right lower limb were recorded during the first and last 15 s of each run. The main result was that neuro-mechanical differences between the shod and barefoot running patterns, classically reported in the absence of fatigue, persisted in the fatigued state. However, in the delayed recovery phase, rearfoot eversion was found to significantly increase in the shod condition. This specific footwear effect is considered as a potential risk factor of overuse injuries in longer runs. Therefore, specific care should be addressed in the delayed recovery phase of SSC fatigue and the use of motion control shoes could be of interest. PMID:26222328

    The current study has been designed to examine the effect of multifunctional drug therapy on carbofuran induced acute (2.187 mg/kg, s.c.) and sub-acute (0.2187 mg/kg, s.c.) neurotoxicity in male wistar rats. Drug treatment which includes nimodipine (Ca(2+) channel blocker), diazepam, ropinirole (dopamine agonist) and GSPE (antioxidant) was started 2h after carbofuran administration. Morris water maze was employed for aiming spatial memory. Narrow beam walk and rotarod were employed for testing motor functions. Brain acetylcholinesterase activity, thiobarbituric acid reactive species, nitrite, reduced glutathione, catalase levels, and mitochondrial complexes were also estimated. Carbofuran treatment resulted in significant development of cognitive and motor functions manifested as impairment in learning and memory along with increased thiobarbituric acid reactive species, nitrite levels and decreased acetylcholinesterase activity, reduced glutathione, catalase levels, and mitochondrial complexes. The standard antidote therapy (atropine) was not able to provide neuroprotection but was able to provide symptomatic relief. The multifunctional drug therapy attenuated carbofuran induced cognitive and motor dysfunction, acetylcholinesterase activity and other biochemical parameters. The triple combination in sub-acute study may be avoided in future as two drug combinations provide adequate neuroprotection. Thus it can be concluded that standard antidotal therapy may not provide neuroprotection while the multifunctional drug therapy offers neuroprotection against carbofuran and may dramatically increase survival and life quality.

    The subjective experience of anxiety plays a central role in cognitive behavioral models of social anxiety disorder (SAD). However, much remains to be learned about the temporal dynamics of anxiety elicited by feared social situations. The aims of the current study were: (1) to compare anxiety trajectories during a speech task in individuals with SAD (n=135) versus healthy controls (HCs; n=47), and (2) to compare the effects of CBT on anxiety trajectories with a waitlist control condition. SAD was associated with higher levels of anxiety and greater increases in anticipatory anxiety compared to HCs, but not differential change in anxiety from pre- to post-speech. CBT was associated with decreases in anxiety from pre- to post-speech but not with changes in absolute levels of anticipatory anxiety or rates of change in anxiety during anticipation. The findings suggest that anticipatory experiences should be further incorporated into exposures.

    With funding from the National Institute on Drug Abuse, we delivered a Web training program on cognitive behavioral therapy (CBT) to addiction counselors and supervisors in 54 U.S. addiction units and conducted a randomized controlled trial with 127 counselors in 2006–07. Adequate adherence to CBT practice at pre- and post-training was judged from audiotapes of client sessions using an adequacy rating guide of counseling skills. A web-administered questionnaire assessed demographics, prior training, attitudes, and self-report counseling practices. Logistic regression model findings are described with discussion of dissemination of evidence-based practices, study limitations, and future research needs for empirically-supported training programs.

    Background Accruing evidence suggests that positive imagery-based cognitive bias modification (CBM) could have potential as a standalone targeted intervention for depressive symptoms or as an adjunct to existing treatments. We sought to establish the benefit of this form of CBM when delivered prior to Internet cognitive behavioral therapy (iCBT) for depression Methods A randomized controlled trial (RCT) of a 1-week Internet-delivered positive CBM vs. an active control condition for participants (N=75, 69% female, mean age=42) meeting diagnostic criteria for major depression; followed by a 10-week iCBT program for both groups. Results Modified intent-to-treat marginal and mixed effect models demonstrated no significant difference between conditions following the CBM intervention or the iCBT program. In both conditions there were significant reductions (Cohen׳s d .57–1.58, 95% CI=.12–2.07) in primary measures of depression and interpretation bias (PHQ9, BDI-II, AST-D). Large effect size reductions (Cohen׳s d .81–1.32, 95% CI=.31–1.79) were observed for secondary measures of distress, disability, anxiety and repetitive negative thinking (K10, WHODAS, STAI, RTQ). Per protocol analyses conducted in the sample of participants who completed all seven sessions of CBM indicated between-group superiority of the positive over control group on depression symptoms (PHQ9, BDI-II) and psychological distress (K10) following CBM (Hedges g .55–.88, 95% CI=−.03–1.46) and following iCBT (PHQ9, K10). The majority (>70%) no longer met diagnostic criteria for depression at 3-month follow-up. Limitations The control condition contained many active components and therefore may have represented a smaller ‘dose’ of the positive condition. Conclusions Results provide preliminary support for the successful integration of imagery-based CBM into an existing Internet-based treatment for depression. PMID:25805405

    Objective To evaluate the efficacy and safety of osmotic-release methylphenidate (OROS-MPH) compared to placebo for attention deficit hyperactivity disorder (ADHD) and impact on substance treatment outcomes in adolescents concurrently receiving cognitive behavioral therapy (CBT) for substance use disorders (SUD). Method 16-week randomized controlled multi-site trial of OROS-MPH + CBT versus placebo + CBT in 303 adolescents (aged 13-18), meeting DSM-IV diagnostic criteria for ADHD and SUD. Primary outcomes: (1) ADHD- clinician-administered ADHD Rating Scale (ADHD-RS), adolescent informant; (2) Substance- adolescent reported days of use in the past 28 days. Secondary outcome measures included parent ADHD-RS and weekly urine drug screens (UDS). Results There were no group differences on reduction in ADHD-RS scores (OROS-MPH: −19.2, 95% confidence interval [CI], −17.1 to −21.2; placebo,−21.2, 95% CI, −19.1 to −23.2) or reduction in days of substance use (OROS-MPH: −5.7 days, 95% CI, 4.0-7.4; placebo: −5.2 days, 95% CI, 3.5-7.0). Some secondary outcomes favored OROS-MPH including lower parent ADHD-RS scores at 8 (mean difference [md]=4.4, 95% CI, 0.8-7.9) and 16 weeks (md=6.9; 95% CI, 2.9-10.9) and more negative UDS in OROS-MPH (mean=3.8) compared to placebo (mean=2.8; P=0.04). Conclusions OROS-MPH did not show greater efficacy than placebo for ADHD or on reduction in substance use in adolescents concurrently receiving individual CBT for co-occurring SUD. However, OROS-MPH was relatively well tolerated and was associated with modestly greater clinical improvement on some secondary ADHD and substance outcome measures. PMID:21871372

    Evidence for the effectiveness of Culturally adapted CBT for psychosis in Low And Middle Income Countries (LAMIC) is limited. Therefore, brief Culturally adapted CBT for psychosis (CaCBTp) targeted at symptoms of schizophrenia for outpatients plus treatment as usual (TAU) is compared with TAU. A total of 116 participants with schizophrenia were recruited from 2 hospitals in Karachi, Pakistan, and randomized into two groups with 1:1 allocation (CaCBTp plus TAU=59, TAU=57). A brief version of CaCBTp (6 individual sessions with the involvement of main carer, plus one session for the family) was provided over 4months. Psychopathology was measured using Positive and Negative Syndrome Scale of Schizophrenia (PANSS), Psychotic Symptom Rating Scales (PSYRATS), and the Schedule for Assessment of Insight (SAI) at baseline and end of therapy. Participants in treatment group, showed statistically significant improvement in all measures of psychopathology at the end of the study compared with control group. Participants in treatment group showed statistically significant improvement in Positive Symptoms (PANSS, Positive Symptoms Subscale; p=0.000), Negative Symptoms (PANSS, Negative Symptoms subscales; p=0.000), Delusions (PSYRATS, Delusions Subscale; p=0.000), Hallucinations (PSYRATS, Hallucination Subscale; p=0.000) and Insight (SAI; p=0.007). The results suggest that brief, Culturally adapted CBT for psychosis can be an effective treatment when provided in combination with TAU, for patients with schizophrenia in a LAMIC setting. This is the first trial of CBT for psychosis from outside the western world. These findings need replicating in other low and middle income countries.

    This phase Ib/II trial combined the pan-deacetylase inhibitor panobinostat with chemotherapy followed by panobinostat maintenance in elderly patients with newly diagnosed acute myeloid leukemia. Patients with prior history of myelodysplastic syndrome were excluded and 38 evaluable patients were included in the study (median age: 71 years; range: 65–83). Study patients received an induction with idarubicin (8 mg/m2 iv days 1–3) plus cytarabine (100 mg/m2 iv days 1–7) plus panobinostat po at escalating doses (days 8, 10, 12, 15, 17 and 19) that could be repeated in non-responding patients. Patients achieving complete remission received a consolidation cycle with the same schema, followed by panobinostat maintenance (40 mg po 3 days/week) every other week until progression. Thirty-one patients were treated at the maximum tolerated dose of panobinostat in the combination (10 mg) with good tolerability. Complete remission rate was 64% with a time to relapse of 17.0 months (12.8–21.1). Median overall survival for the whole series was 17 months (5.5–28.4). Moreover, in 4 of 5 patients with persistent minimal residual disease before maintenance, panobinostat monotherapy reduced its levels, with complete negativization in two of them. Maintenance phase was well tolerated. The most frequent adverse events were thrombocytopenia (25% grades 3/4), and gastrointestinal toxicity, asthenia and anorexia (mainly grades 1/2). Five patients required dose reduction during this phase, but only one discontinued therapy due to toxicity. These results suggest that panobinostat is one of the first novel agents with activity in elderly acute myeloid leukemia patients, and suggest further investigation is warranted, particularly in the context of maintenance therapy. This trial is registered at clinicaltrials.gov identifier: 00840346. PMID:26160880

    We hypothesized that a high-protein diet and/or resveratrol supplementation will improve acute inflammatory responses in rats after receiving experimental abdominal radiation treatment (ART). Based on our previous study, the period of 10 days after ART was used as an acute inflammation model. Rats were exposed to a radiation dose of 17.5 Gy and were supplied with a control (C), 30% high-protein diet (HP), resveratrol supplementation (RES), or HP with RES diet ([HP+RES]). At day 10 after ART, we measured profiles of lipids, proteins, and immune cells in blood. The levels of clusters of differentiating 4(+) (CD4(+)) cells and regulatory T cells, serum proinflammatory cytokines, and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in urine were also measured. ART caused significant disturbances of lipid profiles by increasing triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C), and decreasing high-density lipoprotein cholesterol. The proinflammatroy cytokine levels were also increased by ART. All the experimental diets (HP, RES, and [HP+RES]) significantly decreased levels of TG, monocytes, proinflammatory cytokines, and 8-OHdG, whereas the platelet counts were increased. In addition, the HP and [HP+RES] diets decreased the concentrations of plasma LDL-C and total cholesterol. Also, the HP and RES diets decreased regulatory T cells compared with those of the control diet in ART group. Further, the HP diet led to a significant recovery of white blood cell counts, as well as increased percentages of lymphocyte and decreased percentages of neutrophils. In summary, RES appeared to be significantly effective in minimizing radiation-induced damage to lipid metabolism and immune responses. Our study also demonstrated the importance of dietary protein intake in recovering from acute inflammation by radiation.

    The present study examined the relationship between quality of life and symptom change following group CBT treatment for anxiety or depression in a psychiatric hospital outpatient setting. One hundred seventy seven outpatients undergoing eight sessions of group CBT for anxiety (n=124) or mood disorders (n=53) participated. The Beck Anxiety Inventory (BAI), Zung Self-Rating Depression Scale (Zung-SRDS), Quality of Life Inventory (QOLI), and Satisfaction with Life Scale (SWLS) were administered at baseline and post-treatment. Additionally, the QOLI and SWLS scores of those who achieved reliable improvement or clinically significant symptom change were compared to those who experienced no reliable symptom improvement. There were significant changes across the QOLI, SWLS, BAI and Zung-SRDS outcome measures between baseline and post-treatment, with moderate to very large effect sizes observed. Patients with reliable or clinically significant change in their symptoms experienced significant increases in QOLI and SWLS scores when compared to those whose symptoms did not change reliably. Overall, in a psychiatric hospital outpatient setting, group CBT appeared to be successful in increasing quality of life and satisfaction with life in addition to reducing anxiety and depression symptoms.

    Little research has investigated changes in subjective distress during cognitive-behavioral therapy (CBT) for anxiety disorders in youth. In the current study, 40 youth diagnosed with primary obsessive-compulsive disorder (OCD; M age=11.9 years, 60% male, 80% Caucasian) and 36 parent informants completed separate weekly ratings of child distress for each OC symptom during a 12-session course of CBT. Between-session changes in distress were calculated at the start of, on average throughout, and at the end of treatment. On average throughout treatment, child- and parent-reported decreases in child distress were significant. Baseline OCD severity, functional impairment, and internalizing symptoms predicted degree of change in child distress. Additionally, greater decreases in child distress were predictive of more improved clinical outcomes. Findings advance our understanding of the strengths and limitations of this clinical tool. Future studies should examine youth distress change between and within CBT sessions across both subjective and psychophysiological levels of analysis. PMID:23774008

    Background Building on previous research with disaster-exposed children and adolescents, a randomised clinical trial was performed in the treatment of trauma-related symptoms. In the current study two active treatments were compared among children in a broad age range and from a wide diversity of ethnic populations. Objective The primary aim was to compare the effectiveness and efficiency of Cognitive Behavioural Therapy (CBT) and Eye Movement Desensitisation and Reprocessing (EMDR). Design Children (n=52, aged 4–18) were randomly allocated to either CBT (n=26) or EMDR (n=26) in a disaster mental health after-care setting after an explosion of a fireworks factory. All children received up to four individual treatment sessions over a 4–8 week period along with up to four sessions of parent guidance. Blind assessment took place pre- and post-treatment and at 3 months follow-up on a variety of parent-rated and self-report measures of post-traumatic stress disorder symptomatology, depression, anxiety, and behaviour problems. Analyses of variance (general linear model repeated measures) were conducted on the intention-to-treat sample and the completers. Results Both treatment approaches produced significant reductions on all measures and results were maintained at follow-up. Treatment gains of EMDR were reached in fewer sessions. Conclusion Standardised CBT and EMDR interventions can significantly improve functioning of disaster-exposed children. PMID:22893815

    No increased effect has been associated with parent involvement in cognitive behavioral therapy (CBT) for youths with anxiety disorders. The purpose of this study was to explore parent and therapist experiences of CBT among non-responding youths with anxiety disorders, with a primary focus on parent involvement in therapy. Interpretative phenomenological analysis was applied to 24 sets of semi-structured interviews with families and therapists of anxiety-disordered youths who had not profited from CBT with parental inclusion. From the superordinate theme parents' difficulties acting as co-therapists, which emerged from the analyses, two master themes represented the perspectives of parents (difficulty working together with the youth and feeling unqualified, with limited resources), and two represented the perspectives of therapists (family dynamics stood in the way of progress and difficulty transferring control to parents). Parent and therapist experiences complemented each other, offering two different perspectives on parent difficulties as co-therapists. However, the two groups' views on their respective roles in therapy were in conflict. Parents wished to remain being "just the parents" and for the experts to take over, while therapists wished to act as facilitators transferring the control to parents. Clinical implications are drawn for parental involvement and enhancement of treatment outcomes for likely non-responders.

    This paper examines the sustainability and outcome of Alternatives for Families: A Cognitive-Behavioral Therapy (AF-CBT) as delivered by practitioners in a community-based child protection program who had received training in the model several years earlier. Formerly described as Abuse-Focused CBT, AF-CBT is an evidence-based treatment (EBT) for child physical abuse and family aggression/conflict that was included in the National Child Traumatic Stress Network's initial EBT dissemination efforts in 2002. Seven practitioners participated in a year-long learning collaborative in AF-CBT and in similar training programs for 4 other EBTs. The agency's routine data collection system was used to document the clinical and adjustment outcomes of 52 families presenting with a physically abused child who received their services between 2 and 5 years after the AF-CBT training had ended. Measures of the use of all 5 EBTs documented their frequency, internal consistency, and intercorrelations. Controlling for the unique content of the other four EBTs, the amount of AF-CBT Abuse-specific content delivered was related to improvements on standardized parent rating scales (i.e., child externalizing behavior, anger, anxiety, social competence) and both parent and clinician ratings of the child's adjustment at discharge (i.e., child more safe, less scared/sad, more appropriate with peers). The amount of AF-CBT General content was related to a few discharge ratings (better child prognosis, helpfulness to parents). These novel data provide suggestive evidence for the sustainability and clinical benefits of AF-CBT in an existing community clinic serving physically abused children and their families, and are discussed in the context of key developments in the treatment model and dissemination literature.

    2015-01-01

    In recent studies it has been suggested that Cognitive Behavior Therapy (CBT) is beneficial to people with Autism Spectrum Disorder (ASD) but that the method needs to be modified in relation to their cognitive profile. The aim of this study is to measure the effect of modified CBT, that is, using visualized language throughout the entire session for clients with ASD and anxiety and avoidance behavior. The modification of CBT in this study consists of focusing on CBT protocols for anxiety disorders and depression, while visualizing and systematizing “the invisible” in the conversation, in order for the clients to understand the social, cognitive and emotional context of self and others and how they should interact to avoid misunderstandings. ASD clients may need help to detect the invisible code of social interaction and communication. The level of anxiety and the frequency of target behavior were measured. Four assessments were made, two at the pre-assessment, and one in mid-therapy and end of therapy respectively. Generally, results suggest no improvement during pre-treatment period but a significant improvement during treatment. The values of the clients’ psychological, social and occupational ability to function improved on the Global Function Rating scale. The preliminary conclusion of this pilot study indicates that the use of visualized language throughout the CBT therapy sessions is a promising modification of current CBT protocols for individuals with ASD. After manualization, larger studies with randomized controlled study designs can replicate or challenge these results. PMID:26565732

    We evaluated the relationship between admission renal function (as assessed by estimated glomerular filtration rate (eGFR)), hyperglycemia, and acute insulin resistance, indicated by the homeostatic model assessment (HOMA) index, and their impact on long-term prognosis in 825 consecutive patients with ST-elevation myocardial infarction (STEMI) without previously known diabetes who underwent primary percutaneous coronary intervention (PCI). Admission eGFR showed a significant indirect correlation with admission glycemia (Spearman's ρ -0.23, P < 0.001) and insulin values (Spearman's ρ -0.11, P = 0.002). The incidence of patients with admission glycemia ≥140 mg/dl was significantly higher in patients with eGFR <60 ml/min/m(2) (P < 0.001) as well as the incidence of HOMA positivity (P = 0.002). According to our data, a relationship between renal function and glucose values and acute insulin resistance in the early phase of STEMI was detectable, since a significant, indirect correlation between eGFR, insulin values, and glycemia was observed. Patients with renal dysfunction (eGFR <60 ml/min/1.73 m(2)) exhibited higher glucose values and a higher incidence of acute insulin resistance (as assessed by HOMA index) than those with normal renal function (eGFR ≥60 ml/min/1.73 m(2)). The prognostic role of glucose values for 1-year mortality was confined to patients with eGFR ≥60 ml/min/m(2), who represent the large part of our population and are thought to be at lower risk. In these patients, an independent relationship between 1-year mortality and glucose values was detectable not only for admission glycemia but also for glucose values measured at discharge.

    We tested the hypothesis that vagal withdrawal plays a role in the rapid (phase I) cardiopulmonary response to exercise. To this aim, in five men (24.6+/-3.4 yr, 82.1+/-13.7 kg, maximal aerobic power 330+/-67 W), we determined beat-by-beat cardiac output (Q), oxygen delivery (QaO2), and breath-by-breath lung oxygen uptake (VO2) at light exercise (50 and 100 W) in normoxia and acute hypoxia (fraction of inspired O2=0.11), because the latter reduces resting vagal activity. We computed Q from stroke volume (Qst, by model flow) and heart rate (fH, electrocardiography), and QaO2 from Q and arterial O2 concentration. Double exponentials were fitted to the data. In hypoxia compared with normoxia, steady-state fH and Q were higher, and Qst and VO2 were unchanged. QaO2 was unchanged at rest and lower at exercise. During transients, amplitude of phase I (A1) for VO2 was unchanged. For fH, Q and QaO2, A1 was lower. Phase I time constant (tau1) for QaO2 and VO2 was unchanged. The same was the case for Q at 100 W and for fH at 50 W. Qst kinetics were unaffected. In conclusion, the results do not fully support the hypothesis that vagal withdrawal determines phase I, because it was not completely suppressed. Although we can attribute the decrease in A1 of fH to a diminished degree of vagal withdrawal in hypoxia, this is not so for Qst. Thus the dual origin of the phase I of Q and QaO2, neural (vagal) and mechanical (venous return increase by muscle pump action), would rather be confirmed.

    After ovulation, non-pregnant female giant pandas experience pseudopregnancy. During pseudopregnancy, non-pregnant females exhibit physiological and behavioral changes similar to pregnancy. Monitoring hormonal patterns that are usually different in pregnant mammals are not effective at determining pregnancy status in many animals that undergo pseudopregnancy, including the giant panda. Therefore, a physiological test to distinguish between pregnancy and pseudopregnancy in pandas has eluded scientists for decades. We examined other potential markers of pregnancy and found that activity of the acute phase protein ceruloplasmin increases in urine of giant pandas in response to pregnancy. Results indicate that in term pregnancies, levels of active urinary ceruloplasmin were elevated the first week of pregnancy and remain elevated until 20–24 days prior to parturition, while no increase was observed during the luteal phase in known pseudopregnancies. Active ceruloplasmin also increased during ultrasound-confirmed lost pregnancies; however, the pattern was different compared to term pregnancies, particularly during the late luteal phase. In four out of the five additional reproductive cycles included in the current study where females were bred but no birth occurred, active ceruloplasmin in urine increased during the luteal phase. Similar to the known lost pregnancies, the temporal pattern of change in urinary ceruloplasmin during the luteal phase deviated from the term pregnancies suggesting that these cycles may have also been lost pregnancies. Among giant pandas in captivity, it has been presumed that there is a high rate of pregnancy loss and our results are the first to provide evidence supporting this notion. PMID:21765892

    Aurora kinase overexpression has been observed in patients with hematologic malignancies. MK-0457, a pan-aurora kinase inhibitor that also inhibits the ABL T315I mutant, was evaluated to treat patients with chronic myelogenous leukemia (CML) or Philadelphia chromosome (Ph+) acute lymphoblastic leukemia (ALL) with the T315I mutation. Adults with Ph+ chronic phase (CP)-, accelerated phase (AP)- or blast phase (BP)-CML, or ALL and documented BCR-ABL T315I mutation were treated with a 5-day continuous infusion of MK-0457 administered every 14 days at 40 mg/m2/h, 32 mg/m2/h or 24 mg/m2/h. Fifty-two patients (CP, n=15; AP, n=14; BP, n=11; Ph+ ALL, n=12) were treated. Overall, 8% of patients achieved major cytogenetic response; 6% achieved unconfirmed complete or partial response; 39% had no response. Two patients (CP CML) achieved complete hematologic response. No patients with advanced CML or Ph+ ALL achieved major hematologic response. The most common adverse event (AE) was neutropenia (50%). The most common grade 3/4 AEs were neutropenia (46%) and febrile neutropenia (35%). MK-0457 demonstrated minimal efficacy and only at higher, intolerable doses; lower doses were tolerated and no unexpected toxicities were observed. These data will assist in the development of future aurora kinase inhibitors and in the selection of appropriate target patient populations. PMID:25127392

    Rhesus monkeys (Macaca mulatta) were infected subcutaneously with 1.0 x 10(4) to 1.5 x 10(4) metacyclic trypomastigotes of Trypanosoma cruzi (Colombian strain). Parasitological and immunological parameters were evaluated in these animals for periods of 1 month to over 3 years. A chagoma was observed between the 3rd and the 13th day after infection (a.i.) and patent parasitaemia between the 13th and 59th day a.i.. Thereafter, parasites were demonstrated only by haemoculture and/or xenodiagnosis. Circulating specific IgM and IgG antibodies were observed as early as in the 2nd week a.i. IgG levels persisted until the end of the experiment, but IgM antibodies were detectable nine months a.i. Haematological alterations comprised leucocytosis and lymphocytosis. Electrocardiographic alterations were minor and transient, similar to those observed in non-lethal human acute Chagas' myocarditis. Myocarditis and myositis, characterized by multiple foci of lympho-histiocyte inflammatory infiltrate, were present in monkeys sacrificed on the 41st, 70th and 76th day but not in the animal sacrificed 3 years and 3 months a. i.. The results suggest that Chagas' disease in rhesus monkeys reproduces the acute and indeterminate phases of human Chagas' disease. PMID:2128360

    Aim To report a study conducted to explore intensive care unit nurses’ perceptions of patient participation in the acute phase of chronic obstructive pulmonary disease exacerbation. Background An acute exacerbation is a life-threatening situation, which patients often consider to be extremely frightening. Healthcare personnel exercise considerable power in this situation, which challenges general professional notions of patient participation. Design Critical discourse analysis. Methods In the autumn of 2009, three focus group interviews with experienced intensive care nurses were conducted at two hospitals in western Norway. Two groups had six participants each, and one group had five (N = 17). The transcribed interviews were analysed by means of critical discourse analysis. Findings The intensive care nurses said that an exacerbation is often an extreme situation in which healthcare personnel are exercising a high degree of control and power over patients. Patient participation during exacerbation often takes the form of non-involvement. The participating nurses attached great importance to taking a sensitive approach when meeting patients. The nurses experienced challenging ethical dilemmas. Conclusion This study shows that patient participation should not be understood in universal terms, but rather in relation to a specific setting and the interactions that occur in this setting. Healthcare personnel must develop skill, understanding, and competence to meet these challenging ethical dilemmas. A collaborative inter-professional approach between physicians and nurses is needed to meet the patients’ demand for involvement. PMID:22512673

    This post hoc analysis of the DACO-016 phase III study evaluates the impact of decitabine on transfusion dependence and survival in 485 elderly patients with newly diagnosed acute myeloid leukemia (AML). Red blood cell (RBC) and platelet (PLT) transfusion independence, defined as no transfusions for ≥ 8 consecutive weeks, was measured in both decitabine (n = 242) and treatment choice (TC, n = 243) arms. More RBC transfusion dependent patients at baseline became transfusion independent with decitabine than with TC (26% vs. 13%; p = 0.0026). Similar results were obtained for patients who were PLT transfusion dependent at baseline (31% vs. 13%; p = 0.0069). When excluding patients who attained complete remission (CR), survival was improved in patients who achieved RBC or PLT transfusion independence, suggesting that reaching CR is not a prerequisite for deriving benefit from treatment with decitabine. In addition, patients who achieved transfusion independence with decitabine had increased treatment continuation, even in the absence of CR.

    The technique of in vivo depletion with T cell subset-specific monoclonal antibodies was used to study the involvement of CD8+T cells in protection/pathogenesis during the acute and chronic demyelinating phases of Theiler's murine encephalomyelitis virus (TMEV)-induced disease. Mice rendered CD8-deficient prior to infection with TMEV were less efficient at clearing virus from the central nervous system compared to intact animals and also suffered demyelinating disease of earlier onset and increased severity. This indicates that CD8+ cells have a protective role in virus clearance at early times post-infection, and may also be involved in downregulating the severity of the chronic demyelinating disease. How CD8+ T cells function to produce these effects is discussed.

    Eighteen Dunkin-Hartley guinea pigs and 50 NMRI mice were inoculated with Helicobacter pylori and the infection followed by culture, histopathology, antibody response, and plasma levels of the acute-phase proteins albumin, C3, and transferrin for up to 7 weeks. The immune response to H. pylori surface proteins was studied by an enzyme immunoassay (EIA) and Western immunoblot and the plasma levels of albumin, C3, and transferrin were analyzed by single radial immunodiffusion. Guinea pigs had a more severe gastritis and a higher EIA immune response than NMRI mice. Serum C3 levels were elevated in infected guinea pigs after 3 and 7 weeks indicating a systemic inflammatory response and a possible link between H. pylori infection and extragastric manifestations such as vasculitis associated with atherosclerosis. Serum cholesterol levels were analyzed in guinea pigs at 7 weeks and indicated a higher level in H. pylori-infected than in control animals, but this difference was not statistically significant.

    Patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) not fit for intensive treatment need novel therapy options. Vascular endothelial growth factor (VEGF) receptor inhibition is one potential mechanism by which AML and MDS could be treated. The receptor tyrosine kinase inhibitor AZD2171 (cediranib) has activity against VEGF receptors KDR and FLT-1. This multicenter phase II study was designed to test cediranib's activity in patients with AML or high-risk MDS. The primary endpoint was confirmed disease response defined as a composite of complete remission, partial remission or hematologic improvement. The study enrolled 23 subjects in the AML cohort and 16 subjects in the MDS cohort. There were no confirmed responses in either group. Since the study met the stopping rule after the first stage of enrollment, the trial was closed to further accrual. Common adverse events in both cohorts included thrombocytopenia, neutropenia, anemia, fatigue, dyspnea, diarrhea, nausea and dehydration. PMID:25329007

    The cognitive model of depression posits that cognitive therapy’s (CT) effect on depressive symptoms is mediated by changes in cognitive content (e.g., automatic negative thoughts dysfunctional attitudes, failure attributions). We tested improvement and normalization of cognitive content among outpatients (N = 523) with recurrent major depressive disorder treated with acute-phase CT (Jarrett & Thase, 2010; Jarrett et al., 2013). We also tested whether improvement in cognitive content accounted for subsequent changes in depressive symptoms and vice versa. Five measures of content improved substantively from pre- to post-CT (median d = 0.96), and the proportions of patients scoring in “healthy” ranges increased (median 45% to 82%). Evidence for cognitive mediation of symptom reduction was limited (median r = .06), as was evidence for symptom mediation of cognitive content improvement (median r = .07). We discuss measurement and design issues relevant to detection of mediators and consider alternative theories of change. PMID:26401194

    More than 80% of acute lymphoblastic leukemia (ALL) in pediatric population is curable by using combinations of chemotherapy. However, 20% of the cases still suffer from disease relapse. The most common site of relapse is bone marrow. Relapse of childhood ALL involving the eyeball is rare. However, it occurs in 2.2% of relapsing children. The authors described a 10-year-old Thai boy with underlying ALL on therapy, presented with a one-month history of progressive visual loss of his right eye. The clinical and imaging studies strongly suggested the diagnosis of isolated ocular relapse. In this report, the authors presented the findings from successfully specific treatment consisting of systemic chemotherapy and radiation therapy on the affected eye. From other studies, the outcome was more favorable in cases of ocular relapse off therapy. In our study, one case of isolated ocular relapse ALL was reported.

    Recently studies have indicated the existence of both posttraumatic stress disorder (PTSD) and acute stress disorder (ASD) subtypes but no studies have investigated their mutual association. Although ASD may not be a precursor of PTSD per se, there are potential benefits associated with early identification of victims at risk of developing PTSD subtypes. The present study investigates ASD and PTSD subtypes using latent class analysis (LCA) following bank robbery (N=371). Moreover, we assessed if highly symptomatic ASD and selected risk factors increased the probability of highly symptomatic PTSD. The results of LCA revealed a three class solution for ASD and a two class solution for PTSD. Negative cognitions about self (OR=1.08), neuroticism (OR=1.09) and membership of the 'High symptomatic ASD' class (OR=20.41) significantly increased the probability of 'symptomatic PTSD' class membership. Future studies are needed to investigate the existence of ASD and PTSD subtypes and their mutual relationship.

    In order to identify new compounds to treat Chagas disease during the acute phase with higher activity and lower toxicity than the reference drug benznidazole (Bz), two hydroxyphthalazine derivative compounds were prepared and their trypanocidal effects against Trypanosoma cruzi were evaluated by light microscopy through the determination of IC50 values. Cytotoxicity was determined by flow cytometry assays against Vero cells. In vivo assays were performed in BALB/c mice, in which the parasitemia levels were quantified by fresh blood examination; the assignment of a cure was determined by reactivation of blood parasitemia levels after immunosuppression. The mechanism of action was elucidated at metabolic and ultra-structural levels, by 1H NMR and TEM studies. Finally, as these compounds are potentially capable of causing oxidative damage in the parasites, the study was completed, by assessing their activity as potential iron superoxide dismutase (Fe-SOD) inhibitors. High-selectivity indices observed in vitro were the basis of promoting one of the tested compounds to in vivo assays. The tests on the murine model for the acute phase of Chagas disease showed better parasitemia inhibition values than those found for Bz. Compound 2 induced a remarkable decrease in the reactivation of parasitemia after immunosuppression. Compound 2 turned out to be a great inhibitor of Fe-SOD. The high antiparasitic activity and low toxicity together with the modest costs for the starting materials render this compound an appropriate molecule for the development of an affordable anti-Chagas agent.

    Objective No efficient medical treatment is available for severe acute hepatitis (SAH) except N-acetylcysteine for acetaminophen-induced acute liver failure. The human C-type lectin Reg3α, referred to as ALF-5755, improved survival in an animal model of acute liver failure and was well tolerated in a phase 1 trial in humans. We performed a phase 2a trial of ALF5755 in non-acetaminophen induced SAH. Design double-blind, randomized, placebo-controlled study. The primary end-point was the improvement in the coagulation protein synthesis assessed by the change of Prothrombin (PR) during the 72 hours following treatment initiation calculated as PRH0 minus PRH72 divided by 72 (PR slope H0H72). Intention to treat (ITT) and per-protocol (PP) analysis of the entire group and the Hepatitis B virus (HBV)/AIH (auto-immune hepatitis) sub-group were done separately. Results 57 patients were included. Twenty-eight received ALF-5755, 29 the placebo. Etiologies were: Hepatitis A (n = 10), HBV (n = 13), AIH (n = 9), drug-induced (n = 8), other (n = 17). On the whole group, nor the PR slope H0H72 (0.18±0.31 vs 0.25±0.32), nor the transplant-free survival rate at day 21 (75 vs 86%) differed between groups. Conversely, in the HBV-AIH subgroup, in which ALF was more severe, PR slope H0-H72 was higher in the ALF-5755 arm, the difference being significant in PP analysis (0.048±0.066 vs -0.040±0.099, p = 0.04); the median length of hospitalization was lower in the ALF-5755 group (8 vs 14 days, p = 0.02). Conclusion ALF-5755 was not efficient in a ITT analysis performed on the whole sample; however it led to a significant, although moderate, clinical benefit in a PP analysis of the sub-group of patients with HBV or AIH related SAH. As HBV is the major cause of SAH in Asia and Africa and AIH a growing cause, this study emphasizes the need to pursuit the evaluation of this novel medical treatment of SAH.

    Objective The purpose of this study was to develop a new Internet-based computerized cognitive behavior therapy (iCBT) program in Manga format, the Japanese cartoon, for workers and to examine the effects of the iCBT program on improving subthreshold depression using a randomized controlled trial (RCT) design among workers employed in private companies in Japan. Method All workers in a company (n = 290) and all workers in three departments (n = 1,500) at the headquarters of another large company were recruited by an invitation e-mail. Participants who fulfilled the inclusion criteria were randomly allocated to intervention or control groups (N = 381 for each group). A six-week, six-lesson iCBT program using Manga (Japanese comic) story was developed. The program included several CBT skills: self-monitoring, cognitive restructuring, assertiveness, problem solving, and relaxation. The intervention group studied the iCBT program at a frequency of one lesson per week. Depression (Beck Depression Inventory II; BDI-II) was assessed as a primary outcome at baseline, and three- and six-month follow-ups for both intervention and control groups were performed. Results The iCBT program showed a significant intervention effect on BDI-II (t = −1.99, p<0.05) with small effect sizes (Cohen's d: −0.16, 95% Confidence Interval: −0.32 to 0.00, at six-month follow-up). Conclusions The present study first demonstrated that a computerized cognitive behavior therapy delivered via the Internet was effective in improving depression in the general working population. It seems critical to improve program involvement of participants in order to enhance the effect size of an iCBT program. Trial Registration UMIN Clinical Trials Registry UMIN000006210 PMID:24844530

    Oligosaccharide structures are attached to nearly all membrane and serum proteins, and their composition changes significantly in many diseases. We have analysed glycosylation of IgG heavy chains in 34 patients with juvenile chronic arthritis and 13 control individuals. IgG was purified from 0.7 ml of serum, separated by electrophoresis and transferred on to polyvinylidene difluoride (PVDF) membrane. Ricinus communis agglutinin (RCA I) and Bandeirea simplicifolia (BSA II) and Ulex europaeus (UEA I) lectins were used to measure galactose, N-acetylglucosamine and fucose, respectively. While there was no significant difference in average levels of galactose and N-acetylglucosamine, patients with juvenile chronic arthritis had 2.4 times more fucose attached to IgG heavy chains than control individuals. A different picture emerged when patients were divided into those with acute disease and those in remission. Patients in whom juvenile chronic arthritis was currently active had significantly lower levels of galactose than those in remission, in whom galactose levels were comparable to the control group. Fucose levels in both groups of patients were significantly higher than in the control group. These results show that whereas de-galactosylation is a good test to detect and measure the activity of juvenile chronic arthritis, increased fucosylation is a much more reliable measure for diagnosis of the disease itself.

    ENMD-2076 is a novel, orally-active molecule that inhibits Aurora A kinase, as well as c-Kit, FLT3 and VEGFR2. A phase I study was conducted to determine the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D) and toxicities of ENMD-2076 in patients with acute myeloid leukemia (AML) and chronic myelomonocytic leukemia (CMML). Patients received escalating doses of ENMD-2076 administered orally daily [225 mg (n = 7), 375 mg (n = 6), 325 mg (n = 9), or 275 mg (n = 5)]. Twenty-seven patients were treated (26 AML; 1 CMML-2). The most common non-hematological toxicities of any grade, regardless of association with drug, were fatigue, diarrhea, dysphonia, dyspnea, hypertension, constipation, and abdominal pain. Dose-limiting toxicities (DLTs) consisted of grade 3 fatigue, grade 3 typhilitis, grade 3 syncope and grade 3 QTc prolongation). Of the 16 evaluable patients, one patient achieved a complete remission with incomplete count recovery (CRi), three experienced a morphologic leukemia-free state (MLFS) with a major hematologic improvement in platelets (HI-P), and 5 other patients had a reduction in marrow blast percentage (i.e. 11-65 %). The RP2D in this patient population is 225 mg orally once daily. PMID:27406088

    Tipifarnib (T) exhibits modest activity in elderly adults with newly diagnosed acute myelogenous leukemia (AML). Based on preclinical synergy, a phase 1 trial of T plus etoposide (E) yielded 25% complete remission (CR). We selected 2 comparable dose levels for a randomized phase 2 trial in 84 adults (age range, 70-90 years; median, 76 years) who were not candidates for conventional chemotherapy. Arm A (T 600 mg twice a day × 14 days, E 100 mg days 1-3 and 8-10) and arm B (T 400 mg twice a day × 14 days, E 200 mg days 1-3 and 8-10) yielded similar CR, but arm B had greater toxicity. Total CR was 25%, day 30 death rate 7%. A 2-gene signature of high RASGRP1 and low aprataxin (APTX) expression previously predicted for T response. Assays using blasts from a subset of 40 patients treated with T plus E on this study showed that AMLs with a RASGRP1/APTX ratio of more than 5.2 had a 78% CR rate and negative predictive value 87%. This ratio did not correlate with outcome in 41 patients treated with conventional chemotherapies. The next T-based clinical trials will test the ability of the 2-gene signature to enrich for T responders prospectively. This study is registered at www.clinicaltrials.gov as #NCT00602771.

Arm A (T 600 mg twice a day × 14 days, E 100 mg days 1-3 and 8-10) and arm B (T 400 mg twice a day × 14 days, E 200 mg days 1-3 and 8-10) yielded similar CR, but arm B had greater toxicity. Total CR was 25%, day 30 death rate 7%. A 2-gene signature of high RASGRP1 and low aprataxin (APTX) expression previously predicted for T response. Assays using blasts from a subset of 40 patients treated with T plus E on this study showed that AMLs with a RASGRP1/APTX ratio of more than 5.2 had a 78% CR rate and negative predictive value 87%. This ratio did not correlate with outcome in 41 patients treated with conventional chemotherapies. The next T-based clinical trials will test the ability of the 2-gene signature to enrich for T responders prospectively. This study is registered at www.clinicaltrials.gov as #NCT00602771.

    Nanomolar concentrations of temacrazine (1,4-bis[3-(6-oxo-6H-v-triazolo[4,5,1-de]acridin-5-yl)amino-propyl]piperazine) were discovered to inhibit acute human immunodeficiency virus type 1 (HIV-1) infections and suppress the production of virus from chronically and latently infected cells containing integrated proviral DNA. This bistriazoloacridone derivative exerted its mechanism of antiviral action through selective inhibition of HIV-1 transcription during the postintegrative phase of virus replication. Mechanistic studies revealed that temacrazine blocked HIV-1 RNA formation without interference with the transcription of cellular genes or with events associated with the HIV-1 Tat and Rev regulatory proteins. Although temacrazine inhibited the in vitro 3′ processing and strand transfer activities of HIV-1 integrase, with a 50% inhibitory concentration of approximately 50 nM, no evidence of an inhibitory effect on the intracellular integration of proviral DNA into the cellular genome during the early phase of infection could be detected. Furthermore, temacrazine did not interfere with virus attachment or fusion to host cells or the enzymatic activities of HIV-1 reverse transcriptase or protease, and the compound was not directly virucidal. Demonstration of in vivo anti-HIV-1 activity by temacrazine identifies bistriazoloacridones as a new class of pharmaceuticals that selectively blocks HIV-1 transcription. PMID:9517921

    Aims Acceleration and deceleration capacity (AC and DC) for beat-to-beat short-term heart rate dynamics are powerful predictors of mortality after acute myocardial infarction (AMI). We examined if AC and DC for minute-order long-term heart rate dynamics also have independent predictive value. Methods and results We studied 24-hr Holter electrcardiograms in 708 post-AMI patients who were followed up for up to 30 months thereafter. Acceleration capacity and DC was calculated with the time scales of T (window size defining heart rate) and s (wavelet scale) from 1 to 500 s and compared their prognostic values with conventional measures (ACconv and DCconv) that were calculated with (T,s) = [1,2 (beat)]. During the follow-up, 47 patients died. Both increased ACconv and decreased DCconv predicted mortality (C statistic, 0.792 and 0.797). Concordantly, sharp peaks of C statistics were observed at (T,s) = [2,7 (sec)] for both increased AC and decreased DC (0.762 and 0.768), but there were larger peaks of C statistics at around [30,60 (sec)] for both (0.783 and 0.796). The C statistic was greater for DC than AC at (30,60) (P = 0.0012). Deceleration capacity at (30,60) was a significant predictor even after adjusted for ACconv (P = 0.020) and DCconv (P = 0.028), but the predictive power of AC at (30,60) was no longer significant. Conclusion A decrease in DC for minute-order long-term heart rate dynamics is a strong predictor for post-AMI mortality and the predictive power is independent of ACconv and DCconv for beat-to-beat short-term heart rate dynamics.

    Dengue fever, a public health problem in Brazil, may present severe clinical manifestations as result of an increased vascular permeability and coagulation disorders. T cell activation is a critical event for an effective immune response against infection, including the production of cytokines. We aim to reveal mechanisms that modulate the virus-cell interaction, with an emphasis on cell death. Apoptosis is involved in lymphocyte homeostasis, contributes to the clearance of virus-infected cells but also may play a role in the pathogenesis. Phosphatidylserine exposure on CD8T lymphocytes from dengue patients support early apoptotic processes and loss of genomic integrity, observed by DNA fragmentation in T lymphocytes and indicating late apoptosis. These T cells express activation and cytotoxic phenotypes as revealed by CD29 and CD107a upregulation. Higher frequencies of CD95 were detected in T lymphocytes mainly in those with the cytotoxic profile (CD107a+) and lower levels of anti-apoptotic molecule Bcl-2, suggesting that both CD4+ and CD8+ T cell subsets are more susceptible to apoptosis during acute dengue. The analysis of apoptosis-related protein expression profile showed that not only molecules with pro- but also those with anti-apoptotic functions are overexpressed, indicating that survival mechanisms could be possibly protecting cells against apoptosis caused by viral, immune, oxidative and/or genotoxic stresses. These observations led us to propose that in dengue patients there is an association between T cell susceptibility to apoptosis and the activation state. The mechanisms for understanding the immunopathogenesis during dengue infection are discussed.

    Background During myocardial infarction reduced blood flow in the heart muscle results in cell death. These dying/dead cells have been reported to bind several plasma proteins such as IgM and C-reactive protein (CRP). In the present study we investigated whether fluid-phase complement inhibitor C4b-binding protein (C4BP) would also bind to the infarcted heart tissue. Methods and Findings Initial studies using immunohistochemistry on tissue arrays for several cardiovascular disorders indicated that C4BP can be found in heart tissue in several cardiac diseases but that it is most abundantly found in acute myocardial infarction (AMI). This condition was studied in more detail by analyzing the time window and extent of C4BP positivity. The binding of C4BP correlates to the same locations as C3b, a marker known to correlate to the patterns of IgM and CRP staining. Based on criteria that describe the time after infarction we were able to pinpoint that C4BP binding is a relatively early marker of tissue damage in myocardial infarction with a peak of binding between 12 hours and 5 days subsequent to AMI, the phase in which infiltration of neutrophilic granulocytes in the heart is the most extensive. Conclusions C4BP, an important fluid-phase inhibitor of the classical and lectin pathway of complement activation binds to jeopardized cardiomyocytes early after AMI and co-localizes to other well known markers such as C3b.

    Background While tocolytic therapy can halt the process of delivery, some patients return before the 37th week of pregnancy with recurrence of preterm labor signs. Objectives This study was designed to evaluate the efficacy of progesterone in the prolonging of gestation and reduction of neonatal complications. Material and Methods In a clinical trial in 2010, 110 singleton pregnant women admitted at Imam Reza Hospital, Mashhad, Iran, with the diagnosis of preterm labor were divided into three groups: 400 mg/d vaginal progesterone suppositories; 250 mg/w 17-alpha-hydroxyl-progestrone-caproate; and a control group with no additional treatment. After delivery, we assessed the duration between the first phases of labor to the recurrence of preterm labor. The neonatal complications, apgar score, birth weight, need for admission to NICU, and congenital malformations were compared between groups. Results The mean gestational age was 34± 3 weeks in the first, 33.5 ± 3 weeks in the second and 32.5 ± 2 weeks in the control group. The duration of first phase of labor was 31 ± 17 days in the first, 36 ± 14 days in the second and 26 ± 22 days in the control group. The difference between study groups and the control group was significant (P < 0.005). The complications were lower in progesterone-receiving group in comparison to the control group. Discussion This study reveals that progesterone can significant reduce the rate of recurrent preterm labor and the several possible neonatal complications among women who had treated with tocolytics to suppress the acute phase.

    Nintedanib (BIBF 1120), a potent multikinase inhibitor of VEGFR-1/-2/-3, FGFR-1/-2/-3 and PDGFR-α/-β, exerts growth inhibitory and pro-apoptotic effects in myeloid leukemic cells, especially when used in combination with cytarabine. This phase I study evaluated nintedanib in combination with low-dose cytarabine (LDAC) in elderly patients with untreated or relapsed/refractory acute myeloid leukemia (AML) ineligible for intensive chemotherapy in a 3+3 design. Nintedanib (dose levels 100, 150, and 200 mg orally twice daily) and LDAC (20 mg subcutaneous injection twice daily for 10 days) were administered in 28-day cycles. Dose-limiting toxicity (DLT) was defined as non-hematological severe adverse reaction CTC grade ≥ 4 with possible or definite relationship to nintedanib. Between April 2012 and October 2013, 13 patients (median age 73 [range: 62–86] years) were enrolled. One patient did not receive study medication and was replaced. Nine (69%) patients had relapsed or refractory disease and 6 (46%) patients had unfavorable cytogenetics. The most frequently reported treatment-related adverse events (AE) were gastrointestinal events. Twelve SAEs irrespective of relatedness were reported. Two SUSARs were observed, one fatal hypercalcemia and one fatal gastrointestinal infection. Two patients (17%) with relapsed AML achieved a complete remission (one CR, one CRi) and bone marrow blast reductions without fulfilling PR criteria were observed in 3 patients (25%). One-year overall survival was 33%. Nintedanib combined with LDAC shows an adequate safety profile and survival data are promising in a difficult-to-treat patient population. Continuation of this trial with a phase II recommended dose of 2 x 200 mg nintedanib in a randomized, placebo-controlled phase II study is planned. The trial is registered to EudraCT as 2011-001086-41. Trial Registration: ClinicalTrials.gov NCT01488344 PMID:27716819

    The role of serum amyloid A (SAA) proteins, which are ligands for toll-like receptors, was analyzed in human bone marrow-derived mesenchymal stem cells (hMSCs) and their osteogenic offspring with a focus on senescence, differentiation and mineralization. In vitro aged hMSC developed a senescence-associated secretory phenotype (SASP), resulting in enhanced SAA1/2, TLR2/4 and proinflammatory cytokine (IL6, IL8, IL1β, CXCL1, CXCL2) expression before entering replicative senescence. Recombinant human SAA1 (rhSAA1) induced SASP-related genes and proteins in MSC, which could be abolished by cotreatment with the TLR4-inhibitor CLI-095. The same pattern of SASP-resembling genes was stimulated upon induction of osteogenic differentiation, which is accompanied by autocrine SAA1/2 expression. In this context additional rhSAA1 enhanced the SASP-like phenotype, accelerated the proinflammatory phase of osteogenic differentiation and enhanced mineralization. Autocrine/paracrine and rhSAA1 via TLR4 stimulate a proinflammatory phenotype that is both part of the early phase of osteogenic differentiation and the development of senescence. This signaling cascade is tightly involved in bone formation and mineralization, but may also propagate pathological extraosseous calcification conditions such as calcifying inflammation and atherosclerosis.

    Serial studies have demonstrated that induction therapy with FLAM [flavopiridol (alvocidib) 50 mg/m2 days 1–3, cytarabine 667 mg/m2/day continuous infusion days 6–8, and mitoxantrone (FLAM) 40 mg/m2 day 9] yields complete remission rates of nearly 70% in newly diagnosed poor-risk acute myeloid leukemia. Between May 2011–July 2013, 165 newly diagnosed acute myeloid leukemia patients (age 18–70 years) with intermediate/adverse-risk cytogenetics were randomized 2:1 to receive FLAM or 7+3 (cytarabine 100 mg/m2/day continuous infusion days 1–7 and daunorubicin 90 mg/m2 days 1–3), across 10 institutions. Some patients on 7+3 with residual leukemia on day 14 received 5+2 (cytarabine 100 mg/m2/day continuous infusion days 1–5 and daunorubicin 45 mg/m2 days 1–2), whereas patients on FLAM were not re-treated based on day 14 bone marrow findings. The primary objective was to compare complete remission rates between one cycle of FLAM and one cycle of 7+3. Secondary end points included safety, overall survival and event-free survival. FLAM led to higher complete remission rates than 7+3 alone (70% vs. 46%; P=0.003) without an increase in toxicity, and this improvement persisted after 7+3+/−5+2 (70% vs. 57%; P=0.08). There were no significant differences in overall survival and event-free survival in both arms but post-induction strategies were not standardized. These results substantiate the efficacy of FLAM induction in newly diagnosed AML. A phase III study is currently in development. This study is registered with clinicaltrials.gov identifier: 01349972.

    This review examined the efficacy of cognitive behavior therapy for insomnia (CBT-I) in people diagnosed with cancer. Studies were identified through November 2014 using multiple databases, clinical trial records, and bibliography searches. Inclusion was limited to randomized controlled trials of CBT-I conducted in individuals with a cancer diagnosis who had clinically relevant insomnia. The primary outcome variable was sleep efficiency (SE) as measured by sleep diary. Eight studies including data from 752 cancer survivors met inclusion criteria. CBT-I resulted in a 15.5% improvement in SE relative to control conditions (6.1%) from pre- to post-intervention, with a medium effect size (ES: d = 0.53). Overall, sleep latency was reduced by 22 min with an ES of d = 0.43, compared to a reduction of 8 min in the control conditions. Wake after sleep onset was reduced by 30 min with an ES of d = 0.41, compared to 13 min in the control conditions. Large effect sizes were observed for self-reported insomnia severity (d = 0.77) for those patients who received CBT-I, representing a clinically relevant eight point reduction. Effects were durable up to 6 mo. The quality of the evidence supports a strong recommendation for the use of CBT-I among cancer survivors.

    Background. The global emergence of carbapenem-resistant Enterobacteriaceae highlights the urgent need to reduce carbapenem dependence. The phase 3 RECAPTURE program compared the efficacy and safety of ceftazidime-avibactam and doripenem in patients with complicated urinary tract infection (cUTI), including acute pyelonephritis. Methods. Hospitalized adults with suspected or microbiologically confirmed cUTI/acute pyelonephritis were randomized 1:1 to ceftazidime-avibactam 2000 mg/500 mg every 8 hours or doripenem 500 mg every 8 hours (doses adjusted for renal function), with possible oral antibiotic switch after ≥5 days (total treatment duration up to 10 days or 14 days for patients with bacteremia). Results. Of 1033 randomized patients, 393 and 417 treated with ceftazidime-avibactam and doripenem, respectively, were eligible for the primary efficacy analyses; 19.6% had ceftazidime-nonsusceptible baseline pathogens. Noninferiority of ceftazidime-avibactam vs doripenem was demonstrated for the US Food and Drug Administration co-primary endpoints of (1) patient-reported symptomatic resolution at day 5: 276 of 393 (70.2%) vs 276 of 417 (66.2%) patients (difference, 4.0% [95% confidence interval {CI}, −2.39% to 10.42%]); and (2) combined symptomatic resolution/microbiological eradication at test of cure (TOC): 280 of 393 (71.2%) vs 269 of 417 (64.5%) patients (difference, 6.7% [95% CI, .30% to 13.12%]). Microbiological eradication at TOC (European Medicines Agency primary endpoint) occurred in 304 of 393 (77.4%) ceftazidime-avibactam vs 296 of 417 (71.0%) doripenem patients (difference, 6.4% [95% CI, .33% to 12.36%]), demonstrating superiority at the 5% significance level. Both treatments showed similar efficacy against ceftazidime-nonsusceptible pathogens. Ceftazidime-avibactam had a safety profile consistent with that of ceftazidime alone. Conclusions. Ceftazidime-avibactam was highly effective for the empiric treatment of cUTI (including acute

    The aim of the study was to evaluate the level of proinflammatory cytokines (tumor necrosis factor-α [TNF-α], interleukin-6 [IL-6]), anti-inflammatory cytokine (interleukin-10 [IL-10]), and acute-phase proteins (haptoglobin [Hp] and serum amyloid A [SAA]) in serum and uterine washings in cows that developed endometritis during the early postpartum period. The study was carried out on 40 cows. The experimental group consisted of 20 cows with subclinical endometritis and the control group of 20 cows without endometritis. Analyses in both groups of cows were carried out at 5, 22, and 40 days postpartum (DPP). Experimental material consisted of the blood serum and uterine washings. The levels of the following cytokines: TNF-α, IL-6, IL-10 and acute-phase proteins: Hp and SAA were determined using ELISA. Our study reported that the levels of TNF-α, IL-6, IL-10, Hp, and SAA at 22 DPP were higher in cows with subclinical endometritis (P < 0.001). The levels of TNF-α (P = 0.01), IL-6 and IL-10 (P = 0.001), and Hp (P < 0.001) at 40 DPP were higher in cows with subclinical endometritis compared to healthy cows. The level of IL-10 in uterine washings at 5 DPP was higher (P = 0.001), whereas of SAA was lower (P = 0.01) in cows with subclinical endometritis. At 22 DPP, the levels of IL-6, IL-10, and Hp were higher (P < 0.001) in cows with endometritis. At 40 DPP, the level of TNF-α was lower, whereas these of IL-10 and Hp were elevated (P < 0.001) in cows with endometritis compared to healthy cows. The results indicate that the evaluation of the levels of cytokines and Hp in serum, but primarily in uterine washings, can be an important diagnostic indicator in cows that developed subclinical endometritis. High levels of IL-10 in cows with subclinical endometritis may contribute to the weakening of local resistance mechanisms of the uterus and lead to the persistence of the inflammation in the postpartum period. The present study also shows that the simultaneous examination

    A prevalidation study sponsored by the European Centre for the Validation of Alternative Methods (ECVAM) on in vitro tests for acute skin irritation is aimed at identifying non-animal tests capable of discriminating irritants (I) from non-irritants (NI), as defined according to European Union and OECD. This paper reports on Phase III for one of the methods, the skin integrity function test (SIFT), assessing the protocol performance of the SIFT, in terms of reproducibility and predictive ability, in three laboratories. The barrier function properties of excised mouse skin were determined using a set of 20 coded chemicals (10 I, 10 NI), using the endpoints of trans-epidermal water loss (TEWL) and electrical resistance (ER). The basis of the SIFT prediction model is if the ratios of the pre- and post-application values for either TEWL or ER are greater than five-fold, then the test chemical is deemed irritant (I). If the ratio of both parameters is less than five-fold then the chemical is deemed non-irritant (NI). Analysis of variance (ANOVA) indicated that the intra-lab reproducibility was acceptable but that the inter-lab reproducibility was not. Overall, the SIFT test under-predicted the irritancy of the test chemicals chosen for Phase III with an overall accuracy of only 55%. The sensitivity value (ability to correctly predict I) was only 30%. The specificity (ability to predict NI) of the test was better at 80%. A retrospective examination of the SIFT results was undertaken using Student's t-test and a significance level of P<0.05 to predict an irritant based on changes in the TEWL ratio values. This improved the predictivity of the SIFT test, giving a specificity of 60%, a sensitivity of 80% and an overall accuracy of 70%. Appropriate modifications to the prediction model have now been made and the SIFT will be re-examined in a new validation exercise to investigate the potential of this non-animal method to predict acute skin irritation potential.

    Adverse lung effects following pulmonary exposure to multi-walled carbon nanotubes (MWCNTs) are well documented in rodents. However, systemic effects are less understood. Epidemiological studies have shown increased cardiovascular disease risk after pulmonary exposure to airborne particles, which has led to concerns that inhalation exposure to MWCNTs might pose similar risks. We analyzed parameters related to cardiovascular disease, including plasma acute phase response (APR) proteins and plasma lipids, in female C57BL/6 mice exposed to a single intratracheal instillation of 0, 18, 54 or 162 μg/mouse of small, entangled (CNT{sub Small}, 0.8 ± 0.1 μm long) or large, thick MWCNTs (CNT{sub Large}, 4 ± 0.4 μm long). Liver tissues and plasma were harvested 1, 3 and 28 days post-exposure. In addition, global hepatic gene expression, hepatic cholesterol content and liver histology were used to assess hepatic effects. The two MWCNTs induced similar systemic responses despite their different physicochemical properties. APR proteins SAA3 and haptoglobin, plasma total cholesterol and low-density/very low-density lipoprotein were significantly increased following exposure to either MWCNTs. Plasma SAA3 levels correlated strongly with pulmonary Saa3 levels. Analysis of global gene expression revealed perturbation of the same biological processes and pathways in liver, including the HMG-CoA reductase pathway. Both MWCNTs induced similar histological hepatic changes, with a tendency towards greater response following CNT{sub Large} exposure. Overall, we show that pulmonary exposure to two different MWCNTs induces similar systemic and hepatic responses, including changes in plasma APR, lipid composition, hepatic gene expression and liver morphology. The results link pulmonary exposure to MWCNTs with risk of cardiovascular disease. - Highlights: • Systemic and hepatic alterations were evaluated in female mice following MWCNT instillation. • Despite being physicochemically

Background The extent to which group-based exercise (G-EXE) improves knee range of motion (ROM), quadriceps strength, and gait ability is similar to that of individualized exercise (I-EXE) at 6 weeks and 8 months after total knee arthroplasty (TKA). However, the benefits of G-EXE for patients during the acute recovery phase after TKA remain unclear. Objective To determine the effects of G-EXE during the acute recovery phase after TKA on knee ROM, quadriceps strength, functional ability, and knee pain. Methods Two hundred thirty-one patients participated in G-EXE in addition to regular ambulation and activities-of-daily-living exercises twice daily during the hospital stay. Outcomes were compared to those of a retrospectively identified, historical control group (I-EXE group [n = 206]) that included patients who performed exercises identical to those performed by the G-EXE group. The outcomes included knee ROM, quadriceps strength, pain intensity, and timed up-and-go test score at 1 month before surgery and at discharge. Analyses were adjusted for age, body mass index, sex, length of hospital stay, and preoperative values. Results Changes in ROM of knee flexion and extension (P<.001) and quadriceps strength (P<.001) were significantly better in the G-EXE group than those in the I-EXE group at discharge. The pain intensity improved more in the G-EXE group than in the I-EXE group at discharge (P<.001). However, the changes in the timed up-and-go scores were not significantly different. Conclusion Patients performing G-EXE in addition to regular ambulation and activities-of-daily-living exercises demonstrated greater changes in knee ROM, quadriceps strength, and knee pain than those performing I-EXE in addition to regular ambulation and activities-of-daily-living exercises. The nonrandomized, asynchronous design decreases certainty of these findings. Level of Evidence Therapy, level 2b

    Titanium dioxide nanoparticles (nanoTiO2) are used in various applications including in paints. NanoTiO2 inhalation may induce pulmonary toxicity and systemic effects. However, the underlying molecular mechanisms are poorly understood. In this study, the effects of inhaled surface-coated nanoTiO2 on pulmonary global messenger RNA (mRNA) and microRNA (miRNA) expression in mouse were characterized to provide insight into the molecular response. Female C57BL/6BomTac mice were exposed for 1 hr daily to 42.4 ± 2.9 (SEM) mg surface-coated nanoTiO2/m3 for 11 consecutive days by inhalation and were sacrificed 5 days following the last exposure. Physicochemical properties of the particles were determined. Pulmonary response to nanoTiO2 was characterized using DNA microarrays and pathway-specific PCR arrays and related to data on pulmonary inflammation from bronchial lavages. NanoTiO2 exposure resulted in increased levels of mRNA for acute phase markers serum amyloid A-1 (Saa1) and serum amyloid A-3 (Saa3), several C-X-C and C-C motif chemokines, and cytokine tumor necrosis factor genes. Protein analysis of Saa1 and 3 showed selective upregulation of Saa3 in lung tissues. Sixteen miRNAs were induced by more than 1.2-fold (adjusted P-value < 0.05) following exposure. Real time polymerase chain reaction confirmed the upregulation of miR-1, miR-449a and revealed dramatic induction of miR-135b (60-fold). Thus, inhalation of surface-coated nanoTiO2 results in changes in the expression of genes associated with acute phase, inflammation and immune response 5 days post exposure with concomitant changes in several miRNAs. The role of these miRNAs in pulmonary response to inhaled particles is unknown and warrants further research. Environ. Mol. Mutagen., 2011. © 2011 Wiley-Liss, Inc.† PMID:21259345

    Cognitive behavioral therapy (CBT) with exposure is the state of the art and most efficient treatment for obsessive compulsive disorder and recommended as treatment of 1st choice according to guidelines. Therapies of the third wave, such as mindfulness based approaches (ACT, MBCT), metacognitive therapy, CBASP or schema therapy, have become more popular over past few years. A small number of studies that investigated some of these therapies show promising results. However, due to the small number of available studies, small sample sizes and methodologic limitations (only a few available RCTs) the evidence of these therapies is insufficient. Above all no study compared these alternative therapies with the well-proven CBT and exposure. Therefore, therapies of the third wave should only be used as add-on therapies to CBT and exposure if individually needed in the treatment of OCD. Future research is absolutely needed.

  1. Integrating theories and concepts: formulation driven CBT for a client with a diagnosis of schizo-affective disorder.

    Therapists working with people who have complex problems associated with psychosis may find it difficult to apply currently available cognitive behavioural therapy (CBT) manuals to client's presenting problems. This can lead to activation of negative therapist beliefs about themselves, the client or the therapy and subsequent problems maintaining the therapeutic relationship. This paper describes the integration of a range of models and concepts derived from CBT which were used to assist one such client with complex problems associated with psychosis. As such, it is proposed that taking a flexible, formulation driven approach to therapy can assist therapists to remain client centred and work effectively. The therapy described draws on a number of concepts including those taken from schema focussed therapy, mindfulness and compassionate mind training. Therapist and client summary letters were used as part of the described intervention, but in addition, the client's summary is reproduced in the paper aiming to address the issue of the under reporting in the literature of the client's perspective on therapy.

    Fall accidents among older adults can be devastating events that, in addition to their physical consequences, lead to disabling anxiety warranting the attention of mental health practitioners. This article presents “Back on My Feet,” an exposure-based cognitive-behavioral therapy (CBT) protocol that is designed for older adults with posttraumatic stress disorder (PTSD), subthreshold PTSD, or fear of falling resulting from a traumatic fall. The protocol can be integrated into care once patients have been discharged from hospital or rehabilitation settings back to the community. Following a brief description of its development, the article presents a detailed account of the protocol, including patient evaluation and the components of the eight home-based sessions. The protocol addresses core symptoms of avoidance, physiological arousal/anxiety, and maladaptive thought patterns. Because older patients face different coping challenges from younger patients (for whom the majority of evidence-based CBT interventions have been developed), the discussion ends with limitations and special considerations for working with older, injured patients. The article offers a blueprint for mental health practitioners to address the needs of patients who may present with fall-related anxiety in primary care and other medical settings. Readers who wish to develop their expertise further can consult the online appendices, which include a clinician manual and patient workbook, as well as guidance on additional resources.
