MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Opioid addiction is a national crisis.  As surgery is thought to be a gateway to opioid misuse, opioid-sparing approaches for pain management following surgery are a top priority.

We conducted a meta-analysis of 39 randomized clinical trials of common non-pharmalogical interventions used for postoperative pain management.

We found that acupuncture and electrotherapy following total knee replacement reduced or delayed patients’ opioid use.

MedicalResearch.com: What is the background for this study?

Response: Pregabalin (PG) and gabapentin (GB) are increasingly used for nonspecific Chronic Low Back Pain (CLBP) despite a lack of evidence. There have been concerns expressed over their increased prescribing for various non cancer pain indications in recent years. Their use requires slow titration to therapeutic doses and establishing maintenance on a long-term basis. With prolonged treatment, the potential gain over possible adverse effects and risks could become unclear.

We searched Cochrane, MEDLINE and EMBASE databases for randomized control trials reporting the use of gabapentinoids for chronic lower back pain treatment of 3 months or more in adult patients.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Most international guidelines report an overall lack of efficacy of glucosamine for osteoarthrits. We however know that it is a very heterogeneous disease. Therefore, it is possible that there are certain subgroups of osteoarthritis patients that actually might have effect from glucosamine; for instance subgroups based on different pathologies underlying the clinical presentation, different co-morbidities, or different disease stages.

For investigating efficacy in subgroups large sample sizes are needed, and certain methodological techniques are necessary, to get a valid and robust answer. Several years ago, a group of renowned international osteoarthritis researchers started the OA Trial Bank especially for investigating these subgroup effects of osteoarthritis treatments and collect individual patient data of worldwide-performed intervention studies in osteoarthritis patients. When using the individual patient data of multiple studies, it brings us the large sample size and allows us to use the right methods. We do these subgroup analyses in the OA Trial Bank for many different interventions, not just for glucosamine. The subgroup analyses for glucosamine and for corticosteroid injections are published, the others are ongoing (for instance exercise, orthoses and topicals) or planned and still waiting for funding.

The study did show, however, that glucosamine can be extremely beneficial for pets, and specifically dogs who have joint related issues. Knowing the most valuable sources of glucosamine for dogs is important, as it can be extracted and gained from multiple sources, and each have their own varied levels of quality and potency.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Postoperative pain after total knee arthroplasty (TKA) is a major hurdle for both the patients and the orthopaedists. Many analgesic modalities are currently in use, and can be used alone or in combination in order to augment their effect. Addition of local anesthetic analgesia has been shown to improve pain control and reduce opioid consumption during postoperative period. However, the effects of this analgesia tend to dissipate with time, with the longest duration of action (bupivacaine) of approximately 12 hours. Therefore, long acting local anesthetic (liposomal bupivacaine) has been developed in order to expand the duration of effectiveness of pain relief for up to 96 hours. Many studies evaluated the effectiveness of this anesthetic and demonstrated contradictory results, however, they did not use the same methods and infiltration technique. Therefore, we conducted a prospective, randomized, double-blind, controlled study at 16 hospitals using optimal infiltration techniques. Our study demonstrated significant improvement in pain, decreased opioid consumption, increased time to first opioid rescue, more opioid free patients in liposomal bupivacaine cohort. In addition, there were no unexpected safety concerns.

MedicalResearch.com: What is the background for this study?

Response: The number of patients receiving opioids for chronic pain has risen over the past 2 decades in the US, in parallel with an increase in opioid use disorder. The CDC and professional medical societies have created clinical guidelines to improve the safety of opioid prescribing, yet individual prescribers can find them onerous to implement.

We developed an intervention to change clinical practice to support primary care physicians who prescribe the majority of opioids for chronic pain. The intervention included 4 elements- a nurse care manager to help assess, educate and monitor patients, an electronic registry to keep track of patient data and produce physician level reports, an individualized educational session for the physician by an opioid prescribing expert based on the physician-specific practice information and online resources to help with decision-making for opioid prescribing (www.mytopcare.org). We tested whether the intervention would improve adherence to guidelines, decrease opioid doses and decrease early refills, as a marker of potential prescription opioid misuse among 985 patients of 53 primary care clinicians in four primary care practices.

MedicalResearch.com: What is the background for this study?

Esther Maas, PhD Chronic low back pain causes more disability than any other condition, and has major social and economic consequences. Radiofrequency denervation is a commonly used treatment in pain clinics for a subgroup of patients with chronic low back pain resulting from anatomical structures such as facet joints, sacroiliac joint and intervertebral disc. Radiofrequency denervation uses an electric current that damages the innervating nerve of the painful structure. Despite its frequent application, until now, there was only very low quality and conflicting evidence for its effectiveness. The aim of this study was to establish whether radiofrequency denervation in addition to a standardized exercise program is more effective than the standardized exercise program alone in the selected subgroup of patients with chronic low back pain.

Yoga As Effective As Physical Therapy For Chronic Low Back Pain

MedicalResearch.com Interview with:

Robert B. Saper, MD, MPH Department of Family Medicine Boston Medical Center Boston, MA

Dr. Saper

Robert B. Saper, MD, MPH

MedicalResearch.com: What is the background for this study?

Response: There are a number of studies that show that yoga is effective for chronic low back pain (cLBP), but those studies included mostly white and middle-class individuals as research participants. cLBP disproportionately impacts those who are economically disadvantaged and minorities; they receive less referrals to specialists, less referrals to rehabilitation, and also less patient-education. Therefore, it was important to test whether yoga would be well- received by an underserved population, as well as be an effective form of treating chronic low back pain.

This study consisted of patients from diverse racial and economic backgrounds with multiple medical problems who were able to successfully participate and benefit from both yoga and physical therapy. This study used yoga classes that were specifically designed for people suffering from  chronic low back pain and compared the results of that treatment to those who did physical therapy.

MedicalResearch.com: What are the main findings?

Response: The results show that the yoga was as effective as physical therapy for reducing pain intensity and improving people’s physical function. Patients in the study who did yoga reported that their overall pain intensity went down, that they were able to be more physically active, and a number of patients were also able to reduce or even stop all of their pain medication. The study shows that when yoga is made available and affordable to a diverse population, people of both sexes, people who are disabled, and people of different races and economic backgrounds are both receptive to yoga and, more importantly, can benefit from it.

MedicalResearch.com: What should readers take away from your report?

Response: Doctors should know that a structured yoga program for cLBP is a reasonable, effective, and safe approach for patients with chronic  chronic low back pain. Patients with cLBP should talk with their doctors about different options for treatment of back pain, starting with non-drug approaches like yoga and physical therapy. Policy makers need to examine the potential benefits for patients and cost savings for covering non-pharmacological approaches to pain.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: The cost effectiveness of yoga and physical therapy for chronic low back pain still needs to be looked at carefully, as well as how the medical community can implement yoga classes for back pain widely.

While medication, imaging and invasive procedures absolutely have their place, research and clinical guidelines show that non-pharmacological procedures as first treatment options may be best.

MedicalResearch.com: Is there anything else you would like to add?

Response: Yoga is increasingly popular in the United States, and many yoga teachers are available in urban areas. However, yoga teachers and yoga classes are still relatively rare in communities of color and disadvantaged areas. Therefore, it’s important that we begin to train, build, and make yoga more available to diverse communities. Changing the common view of yoga from a fitness exercise for the healthy and wealthy, to a therapeutic approach for people with chronic pain and other conditions, is also an ongoing challenge.

Finding that yoga is non-inferior to physical therapy makes a strong case that yoga programs like the one in this study should be covered by insurance and offered by health care facilities. When a therapy like yoga is shown to be as effective as standard therapies, it should be made available to everyone regardless of ability to pay. For patients who attended more classes or physical therapy sessions, their cLBP improvement was even greater.

MedicalResearch.com: What is the background for this study?

Response: The GO-ALIVE study (CNTO148AKS3001) is a multicenter, randomized, double-blind, placebo-controlled study of golimumab, an anti-TNFα monoclonal antibody, administered intravenously (IV), in adult patients with active ankylosing spondylitis (AS). The primary objective is to evaluate the efficacy of golimumab 2 mg/kg in patients with active AS by assessing the reduction in signs and symptoms of AS. The secondary objectives include assessing efficacy related to improving physical function, range of motion, health-related quality of life, and other health outcomes.

A total of 208 patients who had a diagnosis of definite  ankylosing spondylitis (per modified New York criteria) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥4, total back pain visual analogue scale (VAS) ≥4, and CRP ≥0.3 mg/dL were randomized.  Patients were treated with IV golimumab (n=105) at Weeks 0, 4, and every 8 weeks through Week 52 or placebo (n=103) at Weeks 0, 4, and 12, with crossover to IV golimumab at Week 16 and through Week 52.

All NSAIDS Raise Risk of Heart Attack, Even When Taken For Short Period of Time

MedicalResearch.com Interview with:
Michèle Bally, BPharm, MSc, PhD

Epidemiologist, Department of Pharmacy, CHUM
Researcher, Health Innovation and Evaluation Hub, CRCHUM

MedicalResearch.com: What is the background for this study?

Response: The objective of this study was to better understand the risk of heart attack associated with using oral prescription non-steroidal anti-inflammatory drugs or NSAIDs (ibuprofen, diclofenac, celecoxib, and naproxen) the way people usually do to treat pain and inflammation in real life circumstances. A lot of people take medication, but they do not understand that some can be more harmful than beneficial, especially with consistent use. Unfortunately, something like a heart attack can happen anywhere. You could be at work and show signs of an attack. If this does happen, hopefully you have someone who is first aid trained to at least help you deal with these symptoms, until you get to the hospital. This is why having someone who knows that they are doing is beneficial in any environment. If it wasn’t for companies like Coast2Coast in Ottawa, the chances of someone who was suffering from a heart attack may not have made it to the hospital if it wasn’t for the assistance of someone who was first aid trained.

In clinical trials, NSAIDs were typically taken on a continuous basis in high standardized doses, as assigned by the trial protocol. However, the dosages and the treatment durations studied in trials may not represent the reality of many patients who use NSAIDs in low or varying doses, use these drugs on and off, or switch between NSAID medications.

We were particularly interested in determining the onset of the risk, that is how soon does the risk of heart attack start increasing? Also, we wanted to investigate the effect of dose and duration of treatment. To do this, we studied the use of a low or high dose level of NSAIDs over certain set periods of time, including taking these medications only for 1 to 7 days.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The opioid epidemic has received tremendous attention in recent years, but most of the focus has been on chronic pain, opioid abuse and overdose. Far less attention has been paid to the importance of acute care prescribing (e.g. surgical pain) in patients that are not chronic opioid users.

We found that 5-6% of patients not using opioids prior to surgery continued to fill prescriptions for opioids long after what would be considered normal surgical recovery. Moreover, the rates of new chronic use did not differ between patients having major and minor surgeries, suggesting that patients continue to use these pain medications for something other than simply pain from surgery. Building on other work by our group, and the few additional studies done on the topic to date, these data suggest that pain medications written for surgery are a major cause of new chronic opioid use for millions of Americans each year.

Dr. Makris is a Rheumatologist, clinically, and spends the majority of time focused on clinical research investigating how to improve outcomes for adults with back pain.

MedicalResearch.com: What is the background for this study?

Response: Back pain is the most common type of musculoskeletal (MSK) pain. We know that expenditures for back pain exceed $100 billion each year (and this was in 2005). Back pain results in tremendous disability (including reduced mobility) and impaired quality of life (not exclusive to physical consequences, but also including important psychosocial repercussions). We also know that statins are prescribed very often, and frequently in younger populations who are active. Some reports suggest that statins may have a protective effect on  musculoskeletal conditions such as back pain.

Modest Effect of Spinal Manipulation For Back Pain

MedicalResearch.com Interview with:

Paul Shekelle, MD PhD MPH Chief of General internal Medicine VA Greater Los Angeles Healthcare System

Dr. Shekelle

Paul Shekelle, MD PhD MPH
Chief of General internal Medicine
VA Greater Los Angeles Healthcare System

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Back pain is one of the commonest symptoms for adult patients to seek health care. For a number of years now, VA has had chiropractic care integrated into the ambulatory care available at many large VA medical centers. Most patients referred from VA primary care to chiropractic clinic have chronic back pain. VA was interested in an evidence synthesis of the use of spinal manipulative therapy in acute low back pain. Spinal manipulative therapy is a manual technique delivered by almost all chiropractors, but also delivered by some physical therapists, osteopathic physicians, and some medical doctors.

The main findings are that spinal manipulative therapy is associated with, on average, a modest beneficial effect on pain and function. However, there are large difference sin outcome across studies, and this suggests that some patients may respond much better, and other may respond not at all.

Dr. Hammoud

Dr. Sommer Hammoud

Dr. Sommer Hammoud MD
ABOS Board Certified Assistant Professor of Orthopedic Surgery
Thomas Jefferson University 

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The background for this exhibit stemmed from the growing problem of prescription opioid abuse in the United States.  As we saw this issue developing, we aimed to investigate the history behind this epidemic, what information we have now to fight it, and what information we need in the future to improve care our patients.

Our main findings for each of those aims are the following:

1) It would appear that a large push at the end of the last century led to a lower threshold to prescribe opiates in the effort to control pain, leading to the current opioid epidemic
2) Mulitmodal methods of pain control and the expanding skill of regional anesthesia can be used to help decrease narcotic use and thus limit exposure to narcotics, and
3) Future research needs to focus on the psychologic aspect of patients’ ability to manage pain and we should strive to be able to categorize patients in order to create an individualized pain management protocol which will most effectively manage pain.

Long-Term Opioid Use Increases With Each Additional Day On Opioid Therapy

MedicalResearch.com Interview with:
Anuj Shah (B.Pharm)

Doctoral Student
Division of Pharmaceutical Evaluation and Policy
University of Arkansas for Medical Sciences

MedicalResearch.com: What is the background for this study?

Response: The CDC guideline on opioid prescribing, published in March 2016, included recommendations for initiation of opioid therapy. The guideline noted that there is a lack of data describing how acute opioid use transitions to long-term opioid use. This report seeks to address this gap by determining characteristics of initial opioid prescribing prognostic of long-term use, among opioid naïve cancer-free adults.

Migraine Associated With Cervical Artery Dissection In Some Young Adults

MedicalResearch.com Interview with:
Alessandro Pezzini, MD, FESO

Professore Associato di Neurologia
Dipartimento di Scienze Cliniche e Sperimentali
Clinica Neurologica
Università degli Studi di Brescia
Italia

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Scarce reports have suggested that a relation might exist between migraine and cervical artery dissection (CEAD), the most frequent cause of ischemic stroke in young adults in Western countries. However, data available so far were obtained from few studies conducted on small cohorts of patients, which limits the generalizability of their findings.

In our study we analysed the data from the Italian Project on Stroke in Young Adults (IPSYS) project, one of the largest registries of young ischemic stroke patients, and observed that migraine, especially the subtype without aura was strongly and independently associated to CEAD. This seems particularly true for men and for people younger than 39 years.

Cedars-Sinai Study Will Address How Doctors Communicate With Patients About Chronic Pain

MedicalResearch.com Interview with:
Michelle S. Keller, MPH, PhD Candidate

Health Policy and Management
Cedars-Sinai
Los Angeles CA 90048

MedicalResearch.com: What is the background for this new funding award?

Response: Research shows that treating and managing chronic pain is tough, and it can be hard for patients and their physicians to be on the same page. Chronic pain touches so many facets of people’s lives—relationships, mental health, sleep, work—that treating it in a 15-minute visit can lead to a lot of frustration and disappointment.

Our hope is that by arming patients and clinicians with evidence-based tools, we can help foster a better dialogue about what is ultimately important to patients, how to achieve fully functional lives while managing chronic pain. We’re testing two different types of communication tools: electronic health record alerts pointing physicians to guidelines when they write opioid prescriptions and patient portal-based tools that can help patients prepare for visits and become active, engaged partners in their care.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: It is a puzzle that troubles the field for many years that how pain and itch, two closely related sensations (once thought as one sensation), are differentiated by the nervous systems. Coding of pain and itch are heatedly debated for decades. The current specificity theory suggests that these two kinds of signals are carried by separate pathways, with some interactions, for example pain can inhibit itch and that explains why we all scratch to inhibit pain. It is true in the periphery (our previous study indicate a small population of neurons in the periphery only codes for itch sensation), but now our study suggests that there could be more crosstalk between these two sensations in the central than we expected.

People might not notice in real life, but in human psychophysical studies, well-isolated experimental environments, when human subjects are given itchy substances, they typically report intense itch sensations accompanied by minor noxious sensations, such as pricking, stinging and burning. Our new leaky gate model suggest in certain circumstances intense itch signals can trigger minor pain sensations, which can explain such phenomenon.

Tele-Rehabilitation Can Improve Physical Function In Chronic Knee Pain Patients

MedicalResearch.com Interview with:
Rachel Nelligan, BPhysio
Physiotherapist & Research Physiotherapist
Department of Physiotherapy | Centre for Health, Exercise and Sports Medicine
The University of Melbourne
Victoria Australia

MedicalResearch.com: What is the background for this study?

Response: This novel study investigated the efficacy of an internet delivered model of service delivery that combined online education, Skype delivered exercise physiotherapy and an Internet-based interactive pain coping skills training program for people with persistent knee pain.

Osteoarthritis, the leading cause of chronic knee pain and disability globally, has a significant individual, societal and economic burden. On an individual level knee osteoarthritis causes loss of function, reduced quality of life, and psychological distress. Clinical guidelines recommend adoption of a biopsychosocial approach to management which should include nondrug, nonsurgical treatments. Specifically exercise, education and psychological interventions (including pain coping skills training (PCST)) that foster self-management are recommended. Evidence identifies that many knee OA sufferers are not receiving adequate management due in part to challenges of accessing these effective treatments. There is an urgent need for new models of health service delivery to rectify this.

Tele-rehabilitation is growing in acceptance as an effective, time efficient and convenient means for people to access effective health interventions. In knee OA internet delivered interventions specifically remotely delivered physiotherapy exercise using specialised tele-rehabilitation equipment and an Internet-based interactive PCST program (PainCOACH), designed to translate key therapeutic elements of clinician-delivered face-to-face PCST, have shown improved patient outcomes. Prior to this study the combination of these two internet-based treatments has not been investigated.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We previously reported the results of a randomized trial examining the effectiveness of Mindfulness-based stress reduction (MBSR) and cognitive behavioral therapy (CBT) for persons with chronic low back pain (Cherkin et al, JAMA, March 22, 2016).

The current report examines whether the relative effectiveness of these approaches compared with usual care that we found after one year were still evident after two years. We found that there was little decrease in the magnitude of the effects of both MBSR and CBT between one and two years, but the two-year outcomes were statistically significant only for chronic low back pain. As previously reported for outcomes up to one year, there were no significant differences in outcomes between CBT and MBSR.

Radiation Therapy Improves Pain and Quality of Life in Bone

MedicalResearch.com Interview with:
Rachel McDonald, MD(C)

Department of Radiation Oncology
Odette Cancer Centre
Sunnybrook Health Sciences Centre
Toronto, Ontario, Canada

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Radiation treatment has been demonstrated in numerous studies to provide effective and timely pain relief to those suffering from painful bone metastases. However, as a palliative treatment, the goal should be not only to reduce pain but also to maintain and even improve quality of life. To date, studies have not effectively demonstrated this; most of these have included either small sample sizes or utilize questionnaires that aren’t tailored to the palliative cancer population with bone metastases.

We aimed to determine how soon after radiation treatment one can expect an improvement in quality of life. Our results showed that patients who had a pain response to radiation also had significantly greater improvements in pain, pain characteristics, functional interference, and psychosocial aspects of well-being at day 10 post-treatment. Further improvements in most domains of quality of life were found for responders at day 42.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Arthroscopic partial meniscectomy is a very common knee surgery. Research evidence has seriously questioned the effect of this type of surgery for degenerative meniscal tears in middle-aged and older patients. Most young patients with traumatic meniscal injury (from sports or similar) also undergo this type of surgery. There is a general understanding that young patients with traumatic tears experience larger improvements in patient reported pain, function and quality of life. However, evidence for this presumption is sparse.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: People with back pain are usually told by their health care practitioners to take analgesic medications to relieve their pain. But our previous research published in the BMJ showed that paracetamol does not have a measurable impact on patient’s symptoms. This resulted in recent changes in guidelines’ recommendations. The 2017 National Institute for Health and Care Excellence (NICE) guidelines/UK no longer recommend paracetamol as a stand-alone intervention for back pain.

So now non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as the analgesic of first choice. However, our results show that compared to placebo, commonly used NSAIDs, such as Ibuprofen (e.g. Nurofen) and Diclofenac (e.g. Voltaren), provide only small benefits for people with back pain while increasing the risk of gastrointestinal adverse effects by 2.5 times.

MedicalResearch.com: What is the background for this study?

Response: Up to one fifth of the general population have migraine, a primary, chronic-intermittent headache disorder affecting the neuronal and vascular systems and characterized by severe headache accompanied by nausea and/or sensory hypersensitivities such as photophobia and phonophobia. In approximately 20-30% of patients, the headache phase is preceded or accompanied by transient focal neurological disturbances presenting as visual symptoms but also sensory, aphasic, or motor symptoms known as migraine aura.

Stroke is responsible for approximately 6.2 million deaths a year and is a leading global cause of long term disability. Considering that more than 50 million patients in hospital and 53 million ambulatory patients undergo surgical procedures in the United States every year.

We found that patients with migraine, particularly migraine with aura, undergoing a surgical procedure are at increased risk of perioperative ischemic stroke and readmission to hospital within 30 days after discharge.

Low Vitamin D Linked To Increased Risk of Chronic Headache

MedicalResearch.com Interview with:

Dr-Jyrki-Virtanen.jpg

Dr. Jyrki Virtanen

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Formation of vitamin D in the skin with UVB light from the sun is a main source of vitamin D during summer months, but in the winter months the UVB light is too weak for vitamin D production. Headache prevalence has been suggested to be related to increasing latitude (less UVB light throughout the year) and possibly to be less prevalent during summer (more UVB light), which suggests a possible role for vitamin D exposure.

Some previous small studies have suggested that low serum vitamin D levels might be associated with more frequent headache or migraine. Our study included 2601 men from the Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) from eastern Finland, aged 42-60 years in 1984-1989, which makes it one of the largest studies so far regarding vitamin D and headache.
