COPD Airway Epithelial Cell-derived Extracellular Vesicles Spread Cellular Senescence via MicroRNA-34a.

Chronic obstructive pulmonary disease (COPD) is associated with the acceleration of lung aging, and the accumulation of senescent cells in lung tissue. MicroRNA (miR)-34a induces senescence by suppressing the anti-aging molecule, sirtuin-1 (SIRT1). Senescent cells spread senescence to neighbouring and distant cells, favouring COPD progression and its comorbidities.

Pulmonary Administration of TLR2/6 Agonist after Allergic Sensitization Inhibits Airway Hyper-Responsiveness and Recruits Natural Killer Cells in Lung Parenchyma.

Asthma is a chronic lung disease with persistent airway inflammation, bronchial hyper-reactivity, mucus overproduction, and airway remodeling. Antagonizing T2 responses by triggering the immune system with microbial components such as Toll-like receptors (TLRs) has been suggested as a therapeutic concept for allergic asthma. The aim of this study was to evaluate the effect of a TLR2/6 agonist, FSL-1 (Pam2CGDPKHPKSF), administered by intranasal instillation after an allergic airway reaction was established in the ovalbumin (OVA) mouse model and to analyze the role of natural killer (NK) cells in this effect.

Aberrant anti-viral response of natural killer cells in severe asthma.

Rhinovirus infections are the main cause of asthma exacerbations. As natural killer (NK) cells are important actors of the antiviral innate response, we aimed at evaluating the functions of NK cells from severe asthma patients in response to rhinovirus-like molecules or rhinoviruses.Peripheral blood mononuclear cells from patients with severe asthma and healthy donors were stimulated with pathogen-like molecules or with the rhinoviruses (RV)-A9 and RV-2.

Is pain at discharge a risk factor for unplanned hospital readmission?

Introduction: Unplanned readmissions are associated with a high cost to health insurances and the incidence of preventable readmissions could be considered as a quality indicator for the initial hospital admission. We aimed to assess the predictive value for unplanned readmission of higher pain scores at discharge of the initial admission as well as of other pain and demographic characteristics. The documentation of significant associations would provide further support for a structured pain management policy.

Pain Intensity in Hospitalized Adults: A Multilevel Analysis of Barriers and Facilitators of Pain Management.

Background: Despite an enhanced interest and evolution in pain management, prevalence remains high. Interventions to optimize pain-related care can only be effective if barriers are identified and accounted for.

Aim: To assess pain intensity and examine its association with patient- (including health literacy defined in this study as "requiring help to read health information"), nurse-, and system-related (including social capital defined as "the importance of network and norms at work") barriers/facilitators to pain management.

Skin Temperature during Cold Pressor Test in Fibromyalgia: an Evaluation of the Autonomic Nervous System?

Introduction: Fibromyalgia (FM) is a common chronic pain disorder characterized by whole-body pain and multiple symptoms. This study investigated potential dysfunctions of the Autonomic Nervous System (ANS) in FM patients through the measurement of the autonomic response during a cold-water test.

Methods: 23 female patients with FM and 15 healthy female controls were recruited.

Hypervigilance for innocuous tactile stimuli in patients with fibromyalgia: an experimental approach.

Background: Hypervigilance, i.e., excessive attention, is often invoked as a potential explanation for the observation that many individuals with fibromyalgia show a heightened sensitivity to stimulation in various sensory modalities, such as touch and hearing.

Fibromyalgia patients and controls are equally accurate in detecting tactile stimuli while observing another in pain: an experimental study.

This study investigated the effects of observing pain in others upon vicarious somatosensory experiences and the detection of somatosensory stimuli in both fibromyalgia (FM) patients and controls. The putative modulatory role of dispositional empathy, hypervigilance to pain, and central sensitization was examined. FM patients (n = 39) and controls (n = 38) saw videos depicting pain-related (hands being pricked) and non-pain-related scenes, while occasionally experiencing vibrotactile stimuli themselves on the left, right, or both hands.

Attention to pain and fear of pain in patients with chronic pain.

To investigate how acceptance of illness affects chronic pain in terms of attention towards pain and fearful thinking of pain. 62 participants (50 women) with chronic pain carried a palmtop computer for 2 weeks. Eight times each day auditory signals were delivered to cue participants to complete questions about their experience.

To control or not? A motivational perspective on coping with pain.

Pain relief is often the primordial treatment objective in pain patients. However, an exclusive focus upon pain relief may have costs. Evidence is accumulating that persistent attempts to gain control over pain may, paradoxically, hinder successful adaptation to pain and increase frustration and limitations due to pain.

Personality traits in chronic pain patients are associated with low acceptance and catastrophizing about pain.

Objective: Pain acceptance is considered important for mental well-being with better functional outcomes for chronic pain patients. The present study explored whether pain-related variables (pain severity, pain interference, pain duration, and pain catastrophizing) and non-pain-related variables (personality traits) influence acceptance and additionally examined the interrelationship between the influencing variables and acceptance.

Methods: One hundred patients with chronic pain from a multidisciplinary pain centre completed self-report questionnaires on acceptance, pain severity, interference of life, pain duration, pain catastrophizing, and personality.

25. Ischemic pain in the extremities and Raynaud's phenomenon.

Two important groups of disorders result from an insufficient blood supply to the extremities: critical vascular disease and the Raynaud's phenomenon. The latter can be subdivided into a primary and a secondary type. Critical ischemic disease is often caused by arteriosclerosis due to hypertension or diabetes.

Flupirtine in pain management: pharmacological properties and clinical use.

Flupirtine is a centrally acting, non-opioid analgesic that is available in a number of European countries for the treatment of a variety of pain states. The therapeutic benefits seen with flupirtine relate to its unique pharmacological properties. Flupirtine displays indirect NDMA receptor antagonism via activation of potassium channels and is the first representative of a pharmacological class denoted the 'selective neuronal potassium channel openers'.

Opioid rotation in the management of chronic pain: where is the evidence?

The management of chronic pain remains a challenge because of its complexity and unpredictable response to pharmacological treatment. In addition, accurate pain management may be hindered by the prejudice of physicians and patients that strong opioids, classified as step 3 medications in the World Health Organization ladder for cancer pain management, are reserved for the end stage of life. Recent information indicates the potential value of strong opioids in the treatment of chronic nonmalignant pain.

Impact of opioid rescue medication for breakthrough pain on the efficacy and tolerability of long-acting opioids in patients with chronic non-malignant pain.

Background: There is little evidence that short-acting opioids as rescue medication for breakthrough pain is an optimal long-term treatment strategy in chronic non-malignant pain. We compared clinical studies of long-acting opioids that allowed short-acting opioid rescue medication with those that did not, to determine the impact of opioid rescue medication use on the analgesic efficacy and tolerability of chronic opioid therapy in patients with chronic non-malignant pain.

Methods: We searched MEDLINE (1950 to July 2006) and EMBASE (1974 to July 2006) using terms for chronic non-malignant pain and long-acting opioids.

Clinical pharmacy in a multidisciplinar team for chronic pain in adults.

The aim of this study was to evaluate the role and the impact of a clinical pharmacist as a member of a multidisciplinary pain team. Although physicians have a good knowledge of pharmacotherapy in the field of pain medication, pharmacy interventions were necessary to enhance the quality of prescribing. On a population of 93 patients, a total of 120 interventions were recorded.

The relevance of monitoring lamotrigine serum concentrations in chronic pain patients.

Lamotrigine is a novel anticonvulsant initially used in epilepsy treatment. Because of its physiological properties it has subsequently been introduced in pain management and has become an interesting co-analgesic, because it inhibits release of excitatory neurotransmitters, influences different sodium, calcium en potassium channels and elevates the GABA levels. A linear relationship appears to exist between serum concentrations, drug activity and clinical outcome.

Impact of long-term use of opioids on quality of life in patients with chronic, non-malignant pain.

Objective: The use of opioids in the management of non-malignant pain remains controversial. For many physicians, pain relief stemming from opioid use is not enough unless there is also a noticeable change in quality of life (QoL) and patient functioning. The impact of long-term opioid treatment on patients' QoL has been investigated in a limited number of trials, and these studies differ considerably with respect to their design and principal findings.

Acceptance of the unpleasant reality of chronic pain: effects upon attention to pain and engagement with daily activities.

This paper investigates whether acceptance was related to less attention to pain, and to more engagement with daily activities. The results of two studies are reported. In a first cross-sectional study, 501 chronic pain patients completed self-report instruments on pain severity, attention to pain and acceptance.
