Osteoarthritis (OA) of the knee is the most common joint disease, characterized by the degeneration of joint cartilage. Intra-articular hyaluronic acid (IAHA) injections are a well-established non-surgical treatment. This retrospective study analyzed knee OA patients receiving IAHA combined with niacinamide injections, assessing pain reduction in relation to patient data, the number of injections, and radiological findings.

Background/objectives: Painkiller use in amateur sports and, especially, in football is increasingly being discussed, but the scientific data on this field are very limited. Therefore, the aim of this study was to investigate the prevalence of painkiller use in amateur football from the perspective of coaches, as well as to determine how and to which extent coaches can influence their teams in terms of painkiller use and prevention.

Methods: Using an online questionnaire, a cross-sectional analysis of painkiller use in German amateur football from the 4th league to the lowest amateur classes was carried out from the perspective of team coaches.

Treatment with dimethyl fumarate (DMF) leads to lymphopenia and infectious complications in a subset of patients with multiple sclerosis (MS). Here, we aimed to reveal immune markers of DMF-associated lymphopenia. This prospective observational study longitudinally assessed 31 individuals with MS by single-cell mass cytometry before and after 12 and 48 weeks of DMF therapy.

Clustering high-dimensional data, such as images or biological measurements, is a long-standing problem and has been studied extensively. Recently, Deep Clustering has gained popularity due to its flexibility in fitting the specific peculiarities of complex data. Here we introduce the Mixture-of-Experts Similarity Variational Autoencoder (MoE-Sim-VAE), a novel generative clustering model.

Current data generation capabilities in the life sciences render scientists in an apparently contradicting situation. While it is possible to simultaneously measure an ever-increasing number of systems parameters, the resulting data are becoming increasingly difficult to interpret. Latent variable modeling allows for such interpretation by learning non-measurable hidden variables from observations.

This article reviews the role of analgesic drugs with a particular emphasis on opioids. Opioids are the oldest and most potent drugs for the treatment of severe pain, but they are burdened by detrimental side effects such as respiratory depression, addiction, sedation, nausea, and constipation. Their clinical application is undisputed in acute (e.

Introduction: The burden of untreated postoperative pain is high.

Objective: This study assessed feasibility of using quality improvement (QI) tools to improve management of perioperative pain in hospitals in multiple developing countries.

Methods: The International Pain Registry and Developing Countries working groups, from the International Association for the Study of Pain (IASP), sponsored the project and PAIN OUT, a QI and research network, coordinated it, and provided the research tools.

The root cap protects the stem cell niche of angiosperm roots from damage. In Arabidopsis, lateral root cap (LRC) cells covering the meristematic zone are regularly lost through programmed cell death, while the outermost layer of the root cap covering the tip is repeatedly sloughed. Efficient coordination with stem cells producing new layers is needed to maintain a constant size of the cap.

Approximately 20% of patients suffering from stroke with pure or predominant sensory symptoms (referred to as sensory stroke patients) develop central poststroke pain (CPSP). It is largely unknown what distinguishes these patients from those who remain pain free. Using quantitative sensory testing (QST), we analyzed the somatosensory profiles of 50 patients with chronic sensory stroke, of which 25 suffered from CPSP.

Objectives: Unrelieved pain is a substantial public health concern necessitating improvements in medical education. The Advancing the Provision of Pain Education and Learning (APPEAL) study aimed to determine current levels and methods of undergraduate pain medicine education in Europe.

Design And Methods: Using a cross-sectional design, publicly available curriculum information was sought from all medical schools in 15 representative European countries in 2012-2013.

Managing a chronic pain patient in the perioperative period.

J Pain Palliat Care Pharmacother

December 2013

The chronic pain patient with and without chronic opioid medication is at risk for under- and overtreatment perioperatively. Careful planning of the perioperative period by the anesthesiologist, the pain service and the surgeon is crucial. Epidural analgesia requires reduction of preoperative opioid doses to a maximum of 50% to avoid withdrawal as well as continuous postanesthesia care unit-monitoring for the first 24 hours.

Background: Human volunteer studies demonstrate ketamine-reversible opioid-induced hyperalgesia, consistent with reports of increased postoperative pain and analgesic consumption. However, recent clinical trials showed controversial results after intraoperative administration of high-dose remifentanil.

Objective: To investigate in lower abdominal surgery patients whether postoperative pain intensity and analgesic consumption are increased following intraoperative high-dose vs.

Unlabelled: PAIN OUT is a European Commission-funded project aiming at improving postoperative pain management. It combines a registry that can be useful for quality improvement and research using treatment and patient-reported outcome measures. The core of the project is a patient questionnaire-the International Pain Outcomes questionnaire-that comprises key patient-level outcomes of postoperative pain management, including pain intensity, physical and emotional functional interference, side effects, and perceptions of care.

Objective: Research has shown that several patients report unmet psychosocial and spiritual needs. While most studies focus on patients with advanced stages of disease, we intended to identify unmet spiritual needs in patients with chronic pain diseases and cancer living in a secular society.

Methods: In an anonymous cross-sectional study, standardized questionnaires were provided to German patients with chronic pain diseases (and cancer), i.

Early initiation of palliative care to address pain and other symptoms offers the potential to improve quality of life for patients with cancer. The approaches to implementing and delivering palliative care and pain management services vary depending on patient needs, available resources, provider training, and clinical setting. This article describes the experiences in developing programs in which the need for early palliative care or pain management services for patients with cancer was recognized.

Molecular dynamics simulations have been performed for liquid formamide using two different types of potential model (OPLS, Cordeiro). The structural results obtained from simulation were compared to experimental (x-ray and neutron diffraction measurements) outcomes. A generally good agreement for both models examined has been found, but in the hydrogen bonded region (2.
