Radiofrequency ablation for shoulder pain: an updated systematic review.

BACKGROUND: Radiofrequency ablation (RFA) is a treatment modality that has been increasingly used for the management of chronic shoulder pain. Serious conditions that can identified as the cause of chronic shoulder pain include rotator cuff disorders, adhesive capsulitis, osteoarthritis, glenohumeral instability, and acromioclavicular joint disorders. Treatment of chronic shoulder pain typically consists of physical therapy, oral and topical medications, intra-articular corticosteroid injections, and even surgery. The aim of this study was to examine the most recent primary and secondary outcomes of RFA for chronic shoulder pain. METHODS: A systematic review was conducted using three different databases including PubMed, MEDLINE, and the Cochrane Database. The key concepts of "radiofrequency ablation" and "shoulder pain" were used. The search took place in June 2023, and it included articles from the past 20 years. RESULTS: Of the 396 articles found, 29 were included in the review. Most studies focused on reduction in pain scores, duration of relief, function, and patient satisfaction. In several studies, RFA was compared to conservative options such as physical therapy or corticosteroid injections. CONCLUSIONS: Overall, RFA shows positive outcomes in terms of the management of chronic shoulder pain. Therefore, RFA can serve as another treatment option for patients who fail conservative management or are not strong surgical candidates. Understanding the outcomes of RFA for chronic shoulder pain can provide patients and clinicians with evidence for the most appropriate treatment.

Radiofrequency ablation for headache pain: an updated systematic review.

BACKGROUND: Radiofrequency ablation (RFA) has many treatment capabilities, one of which includes long term management of chronic headache. As a result, it has been increasingly used, especially in cases of refractory headache pain. Headaches can be classified as primary and secondary and can result from a variety of serious conditions. Types of primary headaches include tension, migraine, and cluster headaches whereas secondary headaches include headaches because of infection or vascular disease, and cervicogenic headaches. Both types can result in serious debility and diminished quality of life. The treatment of chronic headache pain commonly consists of lifestyle modifications, oral medications, and injectable medications. The aim of this study was to investigate the primary and secondary outcomes of RFA for chronic headache pain. METHODS: A systematic review was conducted using three different databases including PubMed, MEDLINE, and the Cochrane Database. The key concepts of "radiofrequency ablation" and "headache" were used. The search took place in June 2023, and it included articles from the past twenty years. RESULTS: Of the 580 articles found, 32 were included in the review. Most studies focused on pain scores, duration of relief, function, and patient satisfaction. In several studies, RFA was used to target various nerves as the pain generator and compared with modalities such as local anesthetic or corticosteroid. CONCLUSIONS: Overall, RFA shows favorable outcomes in the management of chronic headache pain. Therefore, RFA can serve as an alternative treatment option for patients who fail other conservative treatment regimens. Understanding the outcomes of RFA for headache pain can provide patients and clinicians with evidence for the most appropriate treatment strategies.

Management of Fibromyalgia: An Update.

Fibromyalgia, a chronic pain condition marked by abnormal pain processing, impacts a significant part of the population, leading to reduced quality of life and function. Hallmark symptoms include widespread persistent pain, sleep disturbances, fatigue, cognitive dysfunction, and mood changes. Through this updated review, we aim to contribute to the evolving understanding and management of fibromyalgia, offering insights into the diverse tools available to improve the lives of those affected by this challenging condition. Management begins with educating patients to ultimately relieve them of unnecessary testing and provide reassurance. Treatment emphasizes a comprehensive approach, combining nonpharmacological interventions such as aforementioned education, exercise, and psychotherapy, alongside pharmacologic management-namely duloxetine, milnacipran, pregabalin, and amitriptyline-which have consistent benefits for a range of symptoms across the spectrum of fibromyalgia. Notably, drugs like nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen are generally not recommended due to limited efficacy and associated risks. Lastly, a variety of other medications have shown promise, including NMDA-receptor antagonists, naltrexone, and cannabinoids; however, they should be used with caution due to a small amount of evidence and potential for adverse effects.

Computer-Based Training for Cognitive Behavioural Therapy for Substance Use Disorder: A Randomized Controlled Trial Including Quantitative and Qualitative Health and Economic Outcomes: Formation informatisée pour la thérapie cognitivo-comportementale pour les troubles liés à l'usage de substances : un essai randomisé contrôlé y compris les résultats quantitatifs et qualitatifs en matière de santé et d'économie.

OBJECTIVES: Heavy alcohol and drug use is reported by a substantial number of Canadians; yet, only a minority of those experiencing substance use difficulties access specialized services. Computer-Based Training for Cognitive Behavioural Therapy (CBT4CBT) offers a low-cost method to deliver accessible and high-quality CBT for substance use difficulties. To date, CBT4CBT has primarily been evaluated in terms of quantitative outcomes within substance use disorder (SUD) samples in the United States. A comparison between CBT4CBT versus standard care for SUDs in a Canadian sample is critical to evaluate its potential for health services in Canada. We conducted a randomized controlled trial of CBT4CBT versus standard care for SUD. METHODS: Adults seeking outpatient treatment for SUD (N = 50) were randomly assigned to receive either CBT4CBT or treatment-as-usual (TAU) for 8 weeks. Measures of substance use and associated harms and quality of life were completed before and after treatment and at 6-month follow-up. Qualitative interviews were administered after treatment and at follow-up, and healthcare utilization and costs were extracted for the entire study period. RESULTS: Participants exhibited improvements on the primary outcome as well as several secondary outcomes; however, there were no differences between groups. A cost-effectiveness analysis found lower healthcare costs in CBT4CBT versus TAU in a subsample analysis, but more days of substance use in CBT4CBT. Qualitative analyses highlighted the benefits and challenges of CBT4CBT. DISCUSSION: Findings supported an overall improvement in clinical outcomes. Further investigation is warranted to identify opportunities for implementation of CBT4CBT in tertiary care settings.Trial Registration: https://clinicaltrials.gov/ct2/show/NCT03767907.

Evaluating a digital intervention targeting substance use difficultiesPlain Language SummaryWhy was the study done?Heavy alcohol and drug use is frequent in the Canadian population, although very few people have access to treatment. The digital intervention, Computer-Based Training for Cognitive Behavioural Therapy (CBT4CBT), may provide a low-cost, high-quality, and easily accessible method of treatment for substance use difficulties. Limited research on this digital intervention has been conducted in Canadian populations, and few studies thus far have evaluated participants' subjective experience using the intervention, along with the cost on the Canadian healthcare system.What did the researchers do?The research team recruited participants and provided access to either CBT4CBT or to standard care at a mental health hospital for 8 weeks. Participants were asked questions about their substance use and related consequences, quality of life, and thoughts on the treatment they received. Information regarding healthcare use and the cost to the healthcare system was also gathered.What did the researchers find?Participants in both groups improved with regards to their substance use, some related consequences, and psychological quality of life. Participants provided insight on the benefits and challenges of both types of treatment. It was also found that the CBT4CBT intervention was less costly.What do these findings mean?These findings support that adults receiving CBT4CBT and standard care both improved to a similar degree in this sample. Participant feedback may inform future studies of how best to implement this intervention in clinical studies. Future studies with larger samples are needed to further examine whether CBT4CBT can increase access to supports and be beneficial in the Canadian healthcare system.

Spinal Cord Stimulation Waveforms for the Treatment of Chronic Pain.

PURPOSE OF REVIEW: Since the advent of spinal cord stimulation (SCS), advances in technology have allowed for improvement and treatment of various conditions, especially chronic pain. Additionally, as the system has developed, the ability to provide different stimulation waveforms for patients to treat different conditions has improved. The purpose and objective of the paper is to discuss basics of waveforms and present the most up-to-date literature and research studies on the different types of waveforms that currently exist. During our literature search, we came across over sixty articles that discuss the various waveforms we intend to evaluate. RECENT FINDINGS: There are several publications on several waveforms used in clinical practice, but to our knowledge, this is the only educational document teaching on waveforms which provides essential knowledge. There is a gap of knowledge related to understanding wave forms and how they work.

Exemestane plus everolimus and palbociclib in metastatic breast cancer: clinical response and genomic/transcriptomic determinants of resistance in a phase I/II trial.

The landscape of cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) resistance is still being elucidated and the optimal subsequent therapy to overcome resistance remains uncertain. Here we present the final results of a phase Ib/IIa, open-label trial (NCT02871791) of exemestane plus everolimus and palbociclib for CDK4/6i-resistant metastatic breast cancer. The primary objective of phase Ib was to evaluate safety and tolerability and determine the maximum tolerated dose/recommended phase II dose (100 mg palbociclib, 5 mg everolimus, 25 mg exemestane). The primary objective of phase IIa was to determine the clinical benefit rate (18.8%, n = 6/32), which did not meet the predefined endpoint (65%). Secondary objectives included pharmacokinetic profiling (phase Ib), objective response rate, disease control rate, duration of response, and progression free survival (phase IIa), and correlative multi-omics analysis to investigate biomarkers of resistance to CDK4/6i. All participants were female. Multi-omics data from the phase IIa patients (n = 24 tumor/17 blood biopsy exomes; n = 27 tumor transcriptomes) showed potential mechanisms of resistance (convergent evolution of HER2 activation, BRAFV600E), identified joint genomic/transcriptomic resistance features (ESR1 mutations, high estrogen receptor pathway activity, and a Luminal A/B subtype; ERBB2/BRAF mutations, high RTK/MAPK pathway activity, and a HER2-E subtype), and provided hypothesis-generating results suggesting that mTOR pathway activation correlates with response to the trial's therapy. Our results illustrate how genome and transcriptome sequencing may help better identify patients likely to respond to CDK4/6i therapies.

Usefulness of Carotid Ultrasound Screening in Primary Cardiovascular Prevention: A Systematic Review.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide, and its prevention is more cost-effective than the treatment of its complications. Although cardiovascular (CV) risk assessment based on conventional risk factors is the general recommendation, a significant percentage of the population, irrespective of these risk factors, present with subclinical atherosclerosis during carotid Doppler ultrasound (US) imaging. Subclinical atherosclerotic lesions at the carotid bifurcations may be related to the incidence of future CV events and occult atherosclerotic coronary disease. Such patients might benefit from preventive measures if the carotid Doppler US is allowed as a screening tool to detect the extent of carotid stenosis. We aimed to conduct a comprehensive and systematic evaluation of the impact of carotid US screening on CV risk stratification. METHODS: We searched PubMed, Scopus, and ScienceDirect from inception until July 2023. We included literature that examined the impact of carotid US screening on cardiovascular risk factor (CVRF) prevention, CV events, and mortality in adults of all age groups free of symptomatic carotid artery disease. RESULTS: We identified 2 randomized controlled trials (RCTs) and 9 observational studies, including 21,046 participants. The mean age of the participants was 49, and 53% were female. Two RCTs, with 7,064 participants, examined the impact of pictorial knowledge about subclinical carotid atherosclerosis using carotid US versus traditional CVD risk evaluation without any US evidence in primary cardiovascular prevention. Both studies reported remarkable improvement in medication adherence at 1 to 3-year follow-up after carotid US screening with a decrease in Framingham risk score (FRS). Nine observational studies with 13, 982 participants analyzed the evidence of atherosclerosis on carotid US screening and demonstrated that it is a beneficial tool in the early identification of subclinical atherosclerosis and effective therapeutic intervention. CONCLUSION: This systematic review found that pictorial presentation of silent atherosclerosis using carotid US screening has a contributory role in CV risk stratification and prevention of CVD.
