Sickle cell disease (SCD) is a prevalent and complex inherited pain disorder that can manifest as acute vaso-occlusive crises (VOC) and/or chronic pain. Despite their known risks, opioids are often prescribed routinely and indiscriminately in managing SCD pain, because it is so often severe and debilitating. Integrative medicine strategies, particularly non-opioid therapies, hold promise in safe and effective management of SCD pain. However, the lack of evidence-based methods for managing SCD pain hinders the widespread implementation of non-opioid therapies...

OBJECTIVES: This study aimed to determine the physical activity (PA) level of individuals with migraine and examine its effects on pain intensity (PI), disability, and quality of life (QoL). METHODS: Individuals diagnosed with migraine between the ages of 18 and 55 were included in the study. PA levels are assessed by the International PA Questionnaire Short Form (IPAQ-SF), PI with the McGill Melzack Pain Questionnaire, disability with the Migraine Disability Assessment Scale (MIDAS), and QoL with the World Health Organization QoL Scale Short Form (WHOQOL-BREF)...

UNLABELLED: As virtual reality (VR) technology becomes smaller and more affordable, it is gaining in popularity as a tool to address the patient experience of pain and anxiety during invasive procedures. In this study, we explore the effect of VR on the patient experience in two clinical environments of different anxiety levels to propose a possible mechanism of VR on pain and anxiety reduction. METHOD: Twenty-five wound care patients were randomly assigned to either a VR group or non-virtual reality (NVR) group, singly blinded...

Pain is a multifaceted process that encompasses unpleasant sensory and emotional experiences. The essence of the pain process is aversion, or perceived negative emotion. Central sensitization plays a significant role in initiating and perpetuating of chronic pain. Melzack proposed the concept of the "pain matrix", in which brain regions associated with pain form an interconnected network, rather than being controlled by a singular brain region. This review aims to investigate distinct brain regions involved in pain and their interconnections...

The aim of this study is to investigate the effects of Reiki application on pain, anxiety, and quality of life in patients with fibromyalgia. The study was completed with a total of 50 patients: 25 in the experimental group and 25 in the control group. Reiki was applied to the experimental group and sham Reiki to the control group once a week for 4 weeks. Data were collected from the participants using the Information Form, Visual Analog Scale, McGill-Melzack Pain Questionnaire, State-Trait Anxiety Inventory, and Short Form-36...

The use of stimulation of peripheral nerves to test or treat various medical disorders has been prevalent for a long time. Over the last few years, there has been growing evidence for the use of peripheral nerve stimulation (PNS) for treating a myriad of chronic pain conditions such as limb mononeuropathies, nerve entrapments, peripheral nerve injuries, phantom limb pain, complex regional pain syndrome, back pain, and even fibromyalgia. The ease of placement of a minimally invasive electrode via percutaneous approach in the close vicinity of the nerve and the ability to target various nerves have led to its widespread use and compliance...

Currently, pain is considered the fifth vital sign, and its effective relief is a priority in many surgical departments. The aim of this study was to determine the influence of selected factors on the intensity of postoperative pain after orthopedic and gynecological procedures. The study was conducted in a group of 200 patients undergoing orthopedic and gynecological procedures at the County Hospital in Nisko between August 2017 and January 2018. The method of estimation and document analysis was applied in the course of the study...

The sensory inflow from the periphery that triggers innocuous and painful sensations is highly complex, capturing key elements of the nature of any stimulus, its location, intensity, and duration, and converting this to dynamic action potential firing across a wide population of afferents. While sensory afferents are highly specialized to detect these features, their input to the spinal cord also triggers active processing and modulation there which determines its output, to drive the sensory percept experienced and behavioral responses...

The drive to decarbonise our economy needs to be built into our technology development, particularly in the energy storage industry. A method for creating performance targets for battery development based on environmental impact is presented and discussed. By taking the environmental impact assessments from existing lithium-ion battery technology-it is possible to derive energy density, cycle life and % active material targets required to achieve equal or better environmental impacts for emerging technologies to use...

BACKGROUND: Chronic pain in older people is of particular importance not only with regard to negative subjective experience but also as an indicator of the quality of medical care. Brief scales to assess pain may help health professionals with early recognition and treatment to avoid patient suffering. However, these scales should be adapted to the cultural context to provide valid assessments. The aim of this study was to evaluate the psychometric properties of the Polish translation of the Geriatric Pain Measure - 24 (GPM-24) in older people...

BACKGROUND/SIGNIFICANCE: The pain-reducing effect of applying vibration, which is used as a nonpharmacological method in pain management, is explained by the gate control theory developed by Melzack and Wall. Studies that are based on this theory have shown similar results to those of Melzack and Wall, indicating that pain-transmitting nerves are suppressed by vibrations, leading to higher pain thresholds. PURPOSE: The study aimed to evaluate the effect of applying vibration to manage pain during heel lance procedures in newborns...

BACKGROUND: This study aimed to compare posterolateral fusion with transforaminal lumbar interbody fusion (PLF + TLIF) and PLF only in terms of revision surgery rates and complications, as well as functional and radiological outcomes in lumbar spinal stenosis (LSS) patients. METHODS: Seventy-one patients (37 patients in the PLF + TLIF group and 34 patients in the PLF only group) who underwent surgery due to LSS between January 2013 and December 2016 were retrospectively investigated...

BACKGROUND: The phase III PROSELICA (NCT01308580) and FIRSTANA (NCT01308567) trials investigated taxane chemotherapy among men with postdocetaxel metastatic, castration-resistant prostate cancer (mCRPC) or chemotherapy-naïve mCRPC, respectively. We present a post hoc analysis of patient-reported health-related quality of life (HRQL) among patients with or without a clinical (pain, tumor, or prostate-specific antigen [PSA]) response. MATERIALS AND METHODS: PROSELICA and FIRSTANA HRQL and pain data were collected and analyzed using protocol-defined Functional Assessment of Cancer Therapy-Prostate (FACT-P) and McGill-Melzack (Present Pain Intensity scale) questionnaires...

BACKGROUND: Men with metastatic castration-resistant prostate cancer (mCRPC) are living longer, therefore optimizing health-related quality of life (HRQL), as well as survival outcomes, is important for optimal patient care. The aim of this study was to assess the HRQL in patients with mCRPC receiving docetaxel or cabazitaxel. PATIENTS AND METHODS: PROSELICA (NCT01308580) assessed the non-inferiority of cabazitaxel 20 mg/m2 (C20) versus 25 mg/m2 (C25) in patients with mCRPC after docetaxel...

Presents an obituary of Ronald Melzack (1929-2019). Melzack died on Sunday, December 22, 2019, at 10:00 p.m. News of his death spread like wildfire through the network of long-time friends and colleagues who had heard of his imminent passing. At that moment, the world lost a compassionate and caring soul, an advocate for chronic pain sufferers around the globe, and a giant in the international pain community. He is survived by his wife of 59 years, Lucy (née Birch), their son, Joel, and daughter, Lauren. Ron is known for four major accomplishments: establishing Canada's first multidisciplinary pain center at the Montreal General Hospital with neurosurgeon colleague and friend the late Joseph Stratford; the 1965 publication, in Science , of the gate control theory of pain with the late Patrick Wall; development of the McGill Pain Questionnaire and its derivatives; and later in his career, at 60 years of age, publication of the neuromatrix theory of pain, moving the field beyond the spinal gating mechanism into the brain...
