THE EFFECTIVENESS OF GUIDED IMAGERY ON DEPRESSION AND CORTISOL LEVELS IN COLON RECTAL CANCER PATIENTS

Background: Depression in colon rectal cancer patients can inhibit the healing process, increasing the morbidity and mortality. Purpose of the study: This study aims to determine the effectiveness of guided imagery on the level of depression and cortisol. Guided imagery is a relaxation and comfort therapy that can provide a calm effect. Guided imagery is performed by guiding the patient in imagining a beautiful and comfortable place. Research Method: This study uses experimental design. The study sample consist of 52 patients with colon rectal cancer who undergo the treatment. Depression levels and examination of cortisol levels are carried out before and after the intervention. Guided imagery is given to 26 people in the intervention group, and 26 people in the control group for the standard care. Data analysis using independent t-test and dependent t-test if the data is normally distributed. Results: The use of Guided Imagery therapy can reduce the average level of depression in CRC patients but does not show changes in cortisol levels in patient's body

Fixed points for cyclic R-contractions and solution of nonlinear Volterra integro-differential equations

In this paper, we introduce the notion of cyclic R-contraction mapping and then study the existence of fixed points for such mappings in the framework of metric spaces. Examples and application are presented to support the main result. Our result unify, complement, and generalize various comparable results in the existing literature.http://link.springer.com/journal/11784am2016Mathematics and Applied Mathematic

Recent progress in understanding and predicting Atlantic decadal climate variability

Recent Atlantic climate prediction studies are an exciting new contribution to an extensive body of research on Atlantic decadal variability and predictability that has long emphasized the unique role of the Atlantic Ocean in modulating the surface climate. We present a survey of the foundations and frontiers in our understanding of Atlantic variability mechanisms, the role of the Atlantic Meridional Overturning Circulation (AMOC), and our present capacity for putting that understanding into practice in actual climate prediction systems

Obstacles on the way to the clinical visualisation of beta cells: looking for the Aeneas of molecular imaging to navigate between Scylla and Charybdis

For more than a decade, researchers have been trying to develop non-invasive imaging techniques for the in vivo measurement of viable pancreatic beta cells. However, in spite of intense research efforts, only one tracer for positron emission tomography (PET) imaging is currently under clinical evaluation. To many diabetologists it may remain unclear why the imaging world struggles to develop an effective method for non-invasive beta cell imaging (BCI), which could be useful for both research and clinical purposes. Here, we provide a concise overview of the obstacles and challenges encountered on the way to such BCI, in both native and transplanted islets. We discuss the major difficulties posed by the anatomical and cell biological features of pancreatic islets, as well as the chemical and physical limits of the main imaging modalities, with special focus on PET, SPECT and MRI. We conclude by indicating new avenues for future research in the field, based on several remarkable recent results

Research, education and capacity building priorities for violence, abuse and mental health in low- and middle-income countries: an international qualitative survey

Purpose Despite the World Health Organization and United Nations recognising violence, abuse and mental health as public health priorities, their intersection is under-studied in low- and middle-income countries (LMICs). International violence, abuse and mental health network (iVAMHN) members recognised the need to identify barriers and priorities to develop this field. Methods Informed by collaborative discussion between iVAMHN members, we conducted a pilot study using an online survey to identify research, education and capacity building priorities for violence, abuse and mental health in LMICs. We analysed free-text responses using thematic analysis. Results 35 senior (29%) and junior researchers (29%), non-government or voluntary sector staff (18%), health workers (11%), students (11%) and administrators (3%) completed the survey. Respondents worked in 24 LMICs, with 20% working in more than one country. Seventy-four percent of respondents worked in sub-Saharan Africa, 37% in Asia and smaller proportions in Latin America, Eastern Europe and the Middle East. Respondents described training, human resource, funding and sensitivity-related barriers to researching violence, abuse and mental health in LMICs and recommended a range of actions to build capacity, streamline research pathways, increase efficiency and foster collaborations and co-production. Conclusion The intersection between violence, abuse and mental health in LMICs is a priority for individuals with a range of expertise across health, social care and the voluntary sector. There is interest in and support for building a strong network of parties engaged in research, service evaluation, training and education in this field. Networks like iVAMHN can act as hubs, bringing together diverse stakeholders for collaboration, co-production and mutually beneficial exchange of knowledge and skills

The impact of ENSO on Southern African rainfall in CMIP5 ocean atmosphere coupled climate models

We study the ability of 24 ocean atmosphere global coupled models from the Coupled Model Intercomparison Project 5 (CMIP5) to reproduce the teleconnections between El Niño Southern Oscillation (ENSO) and Southern African rainfall in austral summer using historical forced simulations, with a focus on the atmospheric dynamic associated with El Niño. Overestimations of summer rainfall occur over Southern Africa in all CMIP5 models. Abnormal westward extensions of ENSO patterns are a common feature of all CMIP5 models, while the warming of the Indian Ocean that happens during El Niño is not correctly reproduced. This could impact the teleconnection between ENSO and Southern African rainfall which is represented with mixed success in CMIP5 models. Large-scale anomalies of suppressed deep-convection over the tropical maritime continent and enhanced convection from the central to eastern Pacific are correctly simulated. However, regional biases occur above Africa and the Indian Ocean, particularly in the position of the deep convection anomalies associated with El Niño, which can lead to the wrong sign in rainfall anomalies in the northwest part of South Africa. From the near-surface to mid-troposphere, CMIP5 models underestimate the observed anomalous pattern of pressure occurring over Southern Africa that leads to dry conditions during El Niño years

Mycobacteria Attenuate Nociceptive Responses by Formyl Peptide Receptor Triggered Opioid Peptide Release from Neutrophils

In inflammation, pain is regulated by a balance of pro- and analgesic mediators. Analgesic mediators include opioid peptides which are secreted by neutrophils at the site of inflammation, leading to activation of opioid receptors on peripheral sensory neurons. In humans, local opioids and opioid peptides significantly downregulate postoperative as well as arthritic pain. In rats, inflammatory pain is induced by intraplantar injection of heat inactivated Mycobacterium butyricum, a component of complete Freund's adjuvant. We hypothesized that mycobacterially derived formyl peptide receptor (FPR) and/or toll like receptor (TLR) agonists could activate neutrophils, leading to opioid peptide release and inhibition of inflammatory pain. In complete Freund's adjuvant-induced inflammation, thermal and mechanical nociceptive thresholds of the paw were quantified (Hargreaves and Randall-Selitto methods, respectively). Withdrawal time to heat was decreased following systemic neutrophil depletion as well as local injection of opioid receptor antagonists or anti-opioid peptide (i.e. Met-enkephalin, β-endorphin) antibodies indicating an increase in pain. In vitro, opioid peptide release from human and rat neutrophils was measured by radioimmunoassay. Met-enkephalin release was triggered by Mycobacterium butyricum and formyl peptides but not by TLR-2 or TLR-4 agonists. Mycobacterium butyricum induced a rise in intracellular calcium as determined by FURA loading and calcium imaging. Opioid peptide release was blocked by intracellular calcium chelation as well as phosphoinositol-3-kinase inhibition. The FPR antagonists Boc-FLFLF and cyclosporine H reduced opioid peptide release in vitro and increased inflammatory pain in vivo while TLR 2/4 did not appear to be involved. In summary, mycobacteria activate FPR on neutrophils, resulting in tonic secretion of opioid peptides from neutrophils and in a decrease in inflammatory pain. Future therapeutic strategies may aim at selective FPR agonists to boost endogenous analgesia
