Dementia is frequently observed in the elderly, often associated with psychotic symptoms such as delusion or hallucinations, or with behavioral disturbances such as aggressive behavior, wandering, and aimless behavior induced by the psychotic symptoms. This is a double-blind, placebo-controlled study of the effectiveness and safety of risperidone (taken twice daily over 8 weeks) in the treatment of psychotic symptoms in patients with Alzheimer's disease. Assessments of effectiveness include: Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), a scale used for global assessment of symptoms associated with dementia; the Psychosis Cluster Scale of BEHAVE-AD, a subscale that assesses paranoid and delusional ideation as well as hallucination; and Clinical Global Impression-Change (CGI-C), a measure of an improved or aggravated condition. Safety evaluations include the incidence of adverse events throughout the study; physical examinations, electrocardiograms (ECGs), laboratory tests (hematology, biochemistry, urinalysis), and assessment of extrapyramidal symptoms at specified intervals. The study hypothesis is that treatment with risperidone shows greater improvement in psychotic symptoms, as measured by the BEHAVE-AD psychotic cluster score, in patients with Alzheimer's disease, as compared to placebo. In addition, it is hypothesized that risperidone is well tolerated. Risperidone tablets (0.25 mg or 0.50 mg) or placebo tablets taken orally twice daily. Total daily dosage of 0.5mg on Day 1, 1.0mg on Days 3-5, and 1.5mg (maximum dose) on Days 5-13. Optimum dose maintained during Weeks 3-8 of treatment.Dose may be increased or decreased at investigator's discretion.
PURPOSE OF REVIEW: Cachexia is a devasting syndrome which impacts a large number of patients with cancer. This review aims to provide a comprehensive overview of the central mechanisms of cancer cachexia. In particular, it focuses on the role of the central nervous system (CNS), the melanocortin system, circulating hormones and molecules which are produced by and act on the CNS and the psychological symptoms of cancer cachexia.
RECENT FINDINGS: A growing body of evidence suggests that a central mechanism of action underpins this multi-system disorder. Recent research has focused on the role of neuroinflammation that drives the sickness behaviour seen in cancer cachexia, with emphasis on the role of the hypothalamus. Melanocortin receptor antagonists are showing promise in preclinical studies. There are also new pharmacological developments to overcome the short half-life of ghrelin. GDF-15 has been identified as a core target and trials of compounds that interfere with its signalling or its central receptor are underway.
SUMMARY: Understanding the central mechanisms of cancer cachexia is pivotal for enhancing treatment outcomes in patients. While emerging pharmacological interventions targeting these pathways have shown promise, further research is essential.
The present invention aims to determine the levels of cytotoxicity, proliferation, viability, and cell death mechanism of C6 rat glioblastoma cells exposed to halloysite nano-clay with tubular morphology in powder form, comprising aluminosilicate with a positive charge on the lumen, a negatively charged external surface, and halloysite modified with trimethoxypropylsilane. Also, traceability is determined by fluorescence microscopy, establishing the internalization of nanoparticles in the cells by themselves without being doped with drugs. Additionally, a complementary study is performed for characterizing the nanoparticles using infrared, scanning electron microscopy, thermogravimetric analysis, X-ray diffraction, and X-ray energy dispersive spectroscopy. Said nanoparticles and cells are visualized in an optical microscope and an electron microscope to corroborate the presence of their location. Cell viability and proliferation tests showed that halloysite and halloysite modified wit h trimethoxypropylsilane are tolerated in concentrations of up to 0.005-0.5 mg/mL and exposure times of 24, 48, and 72 hours. The cytotoxicity assays show favorable stability over time with no increase in the death mechanism assay, suggesting that the cells did not die due to exposure to the nanoparticles but for lack of nutrients and space. Finally, the halloysite nanoparticles modified with trimethoxypropylsilane show high in-vitro biocompatibility since they are not active in the cellular environment, nor do they cause a change in the morphology of the cells.
Pain is a major challenge for patients with inflammatory arthritis (IA). Depression and anxiety are common comorbidities in IA, associating with worse outcomes. How they relate to pain is uncertain, with existing systematic reviews (a) mainly considering cross-sectional studies, (b) focusing on the relationship between pain and mental health in the context of disease activity/quality of life, and (c) not specifically considering the impact of treating depression/anxiety on pain. This PROSPERO-registered (CRD42023411823) systematic review will address this knowledge-gap by synthesizing evidence to summarise the associations (and potential mediators) between pain and depression/anxiety and evaluate the impact of treating co-morbid depression/anxiety on pain in IA. Relevant databases will be searched, articles screened and their quality appraised (using Joanna Briggs Institute critical appraisal tools) by two reviewers. Eligible studies will include adults with rheumatoid arthritis or spondyloarthritis, be a clinical trial or observational study, and either (a) report the relationship between pain and depression/anxiety (observational studies/baseline trials), or (b) randomise participants to a pharmacological or psychological treatment to manage depression/anxiety with a pain outcome as an endpoint (trials). To synthesise data on the association between pain and depression/anxiety, where available adjusted coefficients from regression models will be pooled in a random-effects meta-analysis. A synthesis without meta-analysis will summarise mediators. To evaluate the impact of treating depression/anxiety on pain, endpoint mean differences between treatment arms will be combined in a random-effects meta-analysis. Through understanding how depression/anxiety contribute to pain in IA, our review has the potential to help optimise approaches to IA pain.
Patients with intraoperative signs of diffuse erythema, urticaria, angioedema, sudden hypotension, tachycardia, bradycardia, arrhythmia, bronchospasm, vomiting, difficulty in ventilation, and end-tidal carbon dioxide (CO2) increase were included in the study. Reactions were graded from I to IV depending on increasing severity (Grade I, presence of cutaneous signs; Grade II, presence of measurable but non-life-threatening symptoms, including cutaneous effects, arterial hypotension, cough, or difficulty in mechanical ventilation; Grade III, presence of life-threatening reactions: cardiovascular arrest, tachycardia or bradycardia, arrhythmias, severe bronchospasm; Grade IV, circulatory inefficacy, cardiac and/or respiratory arrest).

In case of suspicious findings in terms of hypersensitivity reactions during surgery or recovery from anesthesia; the basal serum tryptase level was recorded at the time of the reaction, 2 hours after the reaction, and any time after 24 hours.

The severity of the reaction, vital signs, treatments applied, and medications administered after the reaction were recorded in the pre-prepared follow-up form. Then, skin tests were performed with all exposure agents,latex and chlorhexidine 4-6 weeks after the reaction in accordance with the records kept by the Pediatric Allergy and Immunology Clinic. A wheal diameter of at least 3mm larger than negative control is regarded a positive skin prick test, while in intradermal testing (IDT), a diameter 3 mm larger than the intracutaneously administered depot of the drug solution following 15-20 min is considered positive. Histamine was used as a positive control, and saline as a negative control. For positive skin test cases, basophil activation test was performed with the available drug. Skin prick and intradermal test concentrations were applied according to the recommendations for non-irritant test concentrations published by the European Network for Drug Allergy (ENDA) (8). Specific immunoglobulin E (spIgE) measurements were performed for latex and chlorhexidine on skin test positive cases, and for penicillin before the skin test for one case that experienced anaphylaxis due to antibiotics. The methodology used was ImmunoCAP® (Thermo Fisher Scientific, Uppsala, Sweden). Serum total tryptase levels were measured with ImmunoCAP® (Thermo Fisher Scientific). The increased serum tryptase value was calculated with the following formula: \>1.2\*basal tryptase level +2 mcg/L. In suspicious cases where the latex skin test was not clinically compatible, cutaneous provocation with latex was performed. Comparisons were made with the basophil activation test for positive results in drug skin tests.
Participants in the S4E group will receive the tobacco modules via iPads in a private room. The intervention will last approximately 20 minutes. Content includes the theoretically driven components of S4E: (a)Storytelling scenarios, (b) an introduction video, tobacco use knowledge development, (c) interactive activities, (d) increasing self-efficacy to prevent tobacco use, (e) clinician-youth communication, and (f) highlighting prevention principles. Participants in this group also receive usual care. The Clinic's usual care includes a standard risk behaviors intake form, pamphlets highlighting resources on sexual, physical, and mental health, and other healthcare services. Adolescents will be compensated $20 at baseline and $40 at 30-day follow-up. To minimize bias, randomization will occur prior to baseline assessment.
AIM: Acute injury and subsequent remodelling responses to ST-segment elevation myocardial infarction (STEMI) are major determinants of clinical outcome. Current imaging and plasma biomarkers provide delayed readouts of myocardial injury and recovery. Here, we sought to systematically characterize all microRNAs (miRs) released during the acute phase of STEMI and relate miR release to magnetic resonance imaging (MRI) findings to predict acute and late responses to STEMI, from a single early blood sample.
METHODS AND RESULTS: miRs were quantified in blood samples obtained from patients after primary PCI (PPCI) for STEMI. Cardiac MRI (cMRI) was performed to quantify myocardial edema, infarct size and salvage index. Regression models were constructed to predict these outcomes measures, which were then tested with a validation cohort. Transcoronary miR release was quantified from paired measurements of coronary artery and coronary sinus samples. A cell culture model was used to identify endothelial cell-derived miRs.A total of 72 patients undergoing PPCI for acute STEMI underwent miR analysis and cMRI. About >200 miRs were detectable in plasma after STEMI, from which 128 miRs were selected for quantification in all patients. Known myocardial miRs demonstrated a linear correlation with troponin release, and these increased across the transcoronary gradient. We identified novel miRs associated with microvascular injury and myocardial salvage. Regression models were constructed using a training cohort, then tested in a validation cohort, and predicted myocardial oedema, infarct size and salvage index.
CONCLUSION: Analysis of miR release after STEMI identifies biomarkers that predict both acute and late outcomes after STEMI. A novel miR-based biomarker score enables the estimation of area at risk, late infarct size and salvage index from a single blood sample 6 hours after PPCI, providing a simple and rapid alternative to serial cMRI characterization of STEMI outcome.
We designed the Enhanced Tailored Intervention to build upon our previous research in order to outperform the original tailored intervention, in a cost effective, theoretically guided and data driven manner with potential for dissemination. Participants in the Enhanced Tailored Intervention will receive an interactive technology based intervention that: 1) addresses important SCT constructs for increasing PA that were not significantly changed in the original parent trial (enjoyment/outcome expectations and social support) and 2) provides greater accountability and interactivity for self-monitoring (through text messages), as requested by participants in the original parent trial.
Oxygen therapy delivered with bCPAP as per standard practice, except for the addition of continuous pulse oximetry. Nursing staff will make manual adjustments to Fraction of Inspired Oxygen (FiO2) provided to infants on bCPAP. Oxygen saturations (SpO2) will be monitored by continuous pulse oximetry, and nurses asked to target the range of SpO2 91-95%. Pulse oximeter alarms will be set to alert nurses to periods of hypoxaemia (SpO2\<88%) and hyperoxaemia (SpO2\>96%).
Chronic hepatitis B (CHB) is prevalent in the world, with estimated chronic carriers of 350 millions worldwide. Currently, peginterferon alfa-2a or oral nucleos(t)ides are approved for the treatment with HBeAg positive CHB, with the overall HBeAg seroconversion far from satisfactory. Therefore, efforts on the various combinations with the currently available drugs are needed to improve the overall response rates. The simultaneous combination therapy with oral nucleoside and peginterferon alfa-2a from large-scaled randomized trials did not show a superior response rate over peginterferon alfa-2a monotherapy. Recently, sequential monotherapy with lamivudine for the first 4 weeks, followed by weekly peginterferon alfa-2a has shown favorable HBeAg seroconversion rate over peginterferon alfa-2a monotherapy, based on the assumption that early viral suppression by lamivudine can restore the immune function to facilitate the later immunomodulatory response by peginterferon alfa-2a. With the recent introduction of entecavir, the more potent oral nucleoside with few drug resistance, sequential monotherapy with entecavir can potently suppress HBV DNA with 4 weeks of treatment, which may facilitate the response of peginterferon alfa-2a to achieve HBeAg seroconversion. Therefore, we aimed to conduct a placebo controlled randomized control trial to evaluate of adding entecavir early in the course of therapy can improve the treatment response.
Bilateral LI4 acupuncture is administered before IUD insertion. Pain perception is evaluated by 10 points rated VAS after completion of the procedure.
The patient's arm was placed in external rotation and abducted at 45 degrees. A linear US probe (4-12 MHz) will be placed longitudinally between the coracoid and the humeral head, visualizing the deltoid muscle and subscapularis tendon. 22-gauge needle will be advanced in-plane into the fascial plane between the deltoid muscle and subscapularis tendon. The location of the needle tip will be confirmed by hydrodissection of inter-fascial planes with 3 ml of normal saline. After negative aspiration, a total of 20 mL of bupivacaine 0.5% will be injected in the fascial plane incrementally, aspirating every 5 ml.
Aim: The study was designed to develop and analyze curcumin nanoparticles. Methods: Curcumin nanoparticles were formulated and evaluated. Their efficacy in protecting against brain damage was investigated in a rat model of ischemic stroke, considering motor function, muscle strength and antioxidant enzyme activity. Results: Curcumin nanoparticles displayed a zeta potential of -55 ± 13.5 mV and an average particle size of 51.40 ± 21.70 nm. In ischemic stroke rat models, curcumin nanoparticle treatment significantly improved motor functions, and muscle strength and increased the activities of antioxidant enzymes like glutathione peroxidase, glutathione, glutathione S-transferase, superoxide dismutase and catalase, reducing oxidative stress and inflammation. Conclusion: Curcumin nanoparticles showed significant neuroprotective effects in ischemic stroke models.
BACKGROUND: Asthma is a heterogeneous disorder. This study aimed to identify changes in gene expression and molecular mechanisms associated with moderate to severe asthma.
METHODS: Differentially expressed genes (DEGs) were analyzed in GSE69683 dataset among moderate asthma and its controls as well as between severe asthma and moderate asthma. Key module genes were identified via co-expression analysis, and the molecular mechanism of the module genes was explored through enrichment analysis and gene set enrichment analysis (GSEA). GSE89809 was used to verify the characteristic genes related to moderate and severe asthma.
RESULTS: Accordingly, 2540 DEGs were present between moderate asthma and the control group, while 6781 DEGs existed between severe asthma and moderate asthma. These genes were identified into 14 co-expression modules. Module 7 had the highest positive correlation with severe asthma and was recognized to be a key module by STEM. Enrichment analysis demonstrated that the module genes were mainly involved in oxidative stress-related signaling pathways. The expression of HSPA1A, PIK3CG and PIK3R6 was associated with moderate asthma, while MAPK13 and MMP9 were associated with severe asthma. The AUC values were verified by GSE89809. Additionally, 322 drugs were predicted to target five genes.
CONCLUSION: These results identified characteristic genes related to moderate and severe asthma and their corresponding molecular mechanisms, providing a basis for future research.

1306613 Dyeing keratinic fibres L'OREAL 30 June 1970 [8 July 1969] 31755/70 Heading D1B Keratinic fibres especially human hair are dyed by applying at least one coupling agent and at least one quinone-imine of an oxidation base in aqueous solution at a neutral or alkaline pH optionally in the presence of an oxidising agent. The quinone-imine may be formed from an aromatic or heterocyclic amine having two amino groups or an amino group and a hydroxy group which groups are ortho or para to one another any conventional coupling agent being used. Preferably the coupling agent is applied to the fibres for 5-20 mins followed by rinsing and application of the quinone-imine for 5-30 mins also followed by rinsing. Wetting, dispersing, swelling and penetrating agents may be present also direct dyes e.g. azo and anthraquinone dyes may be added. A two component pack comprises as first component a solution of a coupling component and as second component a quinone imine as a solution or as a powder.
Mycophenolate mofetil (MMF) is absorbed following oral administration and hydrolyzed to mycophenolic acid (MPA), the active metabolite. MPA is a selective, uncompetitive, and reversible inhibitor of inosine monophosphate dehydrogenase (IMPDH), and therefore inhibits the de novo pathway of guanosine nucleotide synthesis without incorporation into DNA. Because T- and B-lymphocytes are critically dependent for their proliferation on de novo synthesis of purines, whereas other cell types can utilize salvage pathways, MPA has potent cytostatic effects on lymphocytes. MPA inhibits proliferative responses of T- and B-lymphocytes to both mitogenic and allospecific stimulation. Addition of guanosine or deoxyguanosine reverses the cytostatic effects of MPA on lymphocytes. MPA also suppresses antibody formation by B-lymphocytes. MPA prevents the glycosylation of lymphocyte and monocyte glycoproteins that are involved in intercellular adhesion to endothelial cells and may inhibit recruitment of leukocytes into sites of inflammation and graft rejection. MMF did not inhibit early events in the activation of human peripheral blood mononuclear cells, such as the production of interleukin-1 (IL-1) and interleukin-2 (IL-2), but did block the coupling of these events to DNA synthesis and proliferation.
Osteoarthritis is a degenerative condition that causes pain, impaired function and affects daily activities. In knee osteoarthritis, there is destruction of cartilage and subchondral bone, with the consequent narrowing of articular space. Besides the biomechanical factors, trauma and obesity; it is believed that inflammation plays an important role. Treatment options for painful knee osteoarthritis are often unsatisfactory, as represented by 40% of patients reporting persisting postoperative pain following total knee arthroplasty . There are no currently approved knee osteoarthritis treatments capable of slowing OA-related structural progression, so the main goals of the conservative treatment are to provide symptomatic relief, improve joint function, and delay surgical intervention. One of the main actions of intra-articular treatments, ranging from corticosteroids to hyaluronic acid (HA) and biologic products is to reduce inflammatory distress within the joint. In recent years, there has been a growing interest in the effects of ozone, which can be safely delivered intra-articularly and whose use is in constant increase in an outpatient setting due to the ease of preparation methods. From the literature, it is widely accepted that ozone has the biological properties of inducing analgesia, anti-inflammatory, and antioxidant effects mediated by activating the cellular metabolism and inhibiting prostaglandin synthesis, reduce edema and inflammation, and therefore reduce pain and improves function in knee osteoarthritis. Intra-articular oxygen-ozone has been used in the medical domain for several decades. Although some articles have reported promising results on the effectiveness of oxygen-ozone in knee osteoarthritis, the evidence is however low . Currently, few RCTs have compared the efficacy and safety of ozone therapy versus HA intra-articular injections in patients affected by knee osteoarthritis. This study will compare the efficacy of OOT injection to HA in patients with symptomatic OA in one knee, who have failed at least one prior conservative OA therapy (e.g. physiotherapy, simple analgesics). This will be done using a double blind, randomized controlled trial with study subjects receiving a cycle of three injection of OOT or HA. The primary efficacy measure will be pain measured by the WOMAC LK 3.1 scale; other measures of efficacy will include function, stiffness, and quality of life. In addition to clinical efficacy measures, safety will be assessed by tracking adverse events. During screening, potential subjects who provide informed consent will be assessed for eligibility. Screening will consist in checking the presence of inclusion and exclusion criteria, including a WOMAC LK 3.1 pain subscale score ≥ 9 and ≤ 19 and by providing objective physiological evidence of OA using the Kellgren-Lawrence scale (assessed from radiographs). Subjects will also provide demographic and medication use information. Baseline X-ray and MRI will be collected.
