Efficacy of pain management strategies in adults with Amyotrophic Lateral Sclerosis (ALS): A Systematic Review.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive muscle weakness. Presence of pain in ALS patients is heterogeneously reported in studies, and mostly underrepresented in symptom scales. The aim of this study is to evaluate the efficacy of pharmacological and non-pharmacological therapeutic modalities for pain management in patients with ALS. A systematic review was conducted in four databases; PubMed, Scopus, Clinicaltrials.gov, and Cochrane-Ovid. Five randomized controlled clinical trials were included regarding pharmacological and non-pharmacological pain management interventions in adult patients with confirmed diagnosis of ALS in whom pain was objectively evaluated. Risk of bias assessment was evaluated using the RoB2.0 tool. Eligible studies were reported as a descriptive analysis. This systematic review was registered with PROSPERO ID: CRD42024495009. Five clinical trials regarding pain management strategies in ALS were eligible for analysis. Two out of five were non-pharmacological approaches whilst the remaining three provided pharmacological therapies. Of these, Mexiletine was efficient in terms of pain relief, particularly between 600 and 900mg per day, whereas Mecasin showed no pain relief at both, high and low doses. Non-pharmacological therapies, such as exercise and osteopathic manual treatment also lacked efficacy in regard to pain management. Clinical trials focusing on pain management strategies for ALS patients are limited. Medical professionals, understandably focused on immediate life-threatening aspects, may inadvertently sideline the nuanced and intricate dimension of pain experienced by patients with ALS.

Pain Management Treatments and Opioid Use Disorder Risk in Medicaid Patients

IntroductionPeople with chronic pain are at increased risk of opioid-misuse. Less is known about the unique risk conferred by each pain management treatment, as treatments are typically implemented together, confounding their independent effects. This study estimated the extent to which pain management treatments were associated with risk of opioid use disorder (OUD) for those with chronic pain, controlling for baseline demographic and clinical confounding variables and holding other pain management treatments at their observed levels. MethodsData were analyzed in 2024 from two chronic pain subgroups within a cohort of non-pregnant Medicaid patients aged 35-64 years, 2016-2019, from 25 states: those with 1) chronic pain and physical disability (CPPD) (N=6,133) or 2) chronic pain without disability (CP) (N=67,438). Nine pain management treatments were considered: prescription opioid i) dose and ii) duration; iii) number of opioid prescribers; opioid co-prescription with iv) benzo- diazepines, v) muscle relaxants, and vi) gabapentinoids; vii) non-opioid pain prescription, viii) physical therapy, and ix) other pain treatment modality. The outcome was OUD risk. ResultsHaving opioids co-prescribed with gabapentin or benzodiazepine was statistically significantly associated with a 37-45% increased OUD risk for the CP subgroup. Opioid dose and duration also were significantly associated with increased OUD risk in this subgroup. Physical therapy was significantly associated with an 18% decreased risk of OUD in the CP subgroup. ConclusionsCo-prescription of opioids with either gabapentin or benzodiazepines may substantially increase OUD risk. More positively, physical therapy may be a relatively accessible and safe pain management strategy.

Factors influencing nurses' practice of skin-to-skin contact as a pain management intervention for preterm infants

PurposeTo identify contextual as well as individual (personal and professional) factors influencing the practice of skin-to-skin contact (SSC) by nurses as a pain management intervention for preterm infants. SSC is among the most effective non-pharmacological interventions to manage procedural pain in preterm infants. MethodsIn this secondary analysis of a comparative international cross-sectional design study, 202 nurses were recruited and completed self-administered questionnaires. A mixed model was conducted. ResultsThe contextual factors correlated with the use of SSC for pain management included the country (p < 0.001) and work shift (p < 0.001). Individual nurse factors were level of education (p < 0.001), motherhood history (p < 0.001) as well as self-reported skin-to-skin practices [p < 0.001] (positive attitudes, education, and implementation). ConclusionMany factors may contribute to explain the differences in the use of SSC for pain management by nurses. These factors could be of relevant to consider when implanting SSC to manage procedural pain in preterm neonates.

The genetic landscape of osteogenesis imperfecta: mutational mechanisms and therapeutic targets

Osteogenesis imperfecta is colloquially known as brittle bone disease because it is an inherited disease characterized by a connective tissue disorder that causes decreased bone mass, increased bone fragility and abnormalities in skeletal structure. This disease is caused by a mutation in the type I collagen genes, specifically COL1A1 and COL1A2, resulting in a variety of clinical manifestations ranging from mild to lethal. The impact on the quality of life of patients with OI can be complicated, which is why they need multidisciplinary management strategies including orthopedic care, physical therapy, pain management and surgical interventions.

Bridging the genetic gulf: a deep dive into neurotransmission, pharmacogenomics, and genetic variations for optimal pain management

Pain embodies a complex sensory experience influenced by a medley of biological, psychological, and genetic. Pain perception can be classed into four main categories: nociceptive pain, neuropathic pain, acute pain, and chronic pain. Genetic polymorphisms, which are basically genetic variations in DNA sequences, have a part to play in the neurotransmission pathways associated with pain perception and the ultimate effectiveness of pain management interventions. Learning about the effects of genetics on neurotransmission in pain management offers a fresh viewpoint on individual variations in pain sensitivity, response to treatment, and the development of personalised approaches to pain management. A closer look at the relationship between genetic polymorphisms and neurotransmission provides a better understanding deep down at the genetic level. These chemical messengers, neurotransmitters, help pass signals between nerve cells; they are essential for pain processing and modulation. Differences in genetic makeup in neurotransmitter-related genes could change how these genes express, function, and regulate, thus changing how humans perceive pain and respond to pain management interventions. The conjunction of neurotransmission and pharmacogenomics forms a unique convergence, composing a narrative that discloses the percipient influence of individual genetic differences on neural communication and responses to pharmaceuticals. These genetic variations elaborately construct the molecular architecture supervising neurotransmitter release, receptor interactions, and enzymatic processes within the nervous system. In this review, the convergence of neurotransmission, pharmacogenomics, and genetic variations illuminates a pivotal realm in healthcare. Genetic variations intricately influence neurotransmission pathways, moulding individual responses to pharmacological interventions. This intersection not only underscores the complexity of human biology but also holds the promise of personalised healthcare solutions. Recognising subtle genetic variations in neurotransmission and pharmacogenomics opens the door to precision medicine, tailoring treatments to individual genetic codes and revolutionising our approach to medical care.

Physical pain among family caregivers to older adults: A scoping review of the literature.

Scholarship on the health of family caregivers to older adults continues to expand. Although existing research suggests that many family caregivers experience pain, which impacts their ability to perform caregiving tasks and is associated with care recipients' unmet needs, the scope of research on family caregivers' pain remains poorly characterized. We conducted a scoping review of research on pain among family caregivers to older adults to characterize existing evidence and identify knowledge gaps. We searched multiple databases spanning from January 2012 to July 2023, identified eligible studies using predefined inclusion/exclusion criteria, and extracted key data (e.g., study design/methodology, pain measurement, caregiver pain type, and major findings). We identified 46 eligible studies conducted in the United States (n = 19) and internationally (n = 27). Studies often focused on caregivers for older adults with specific health conditions, such as cancer (n = 11), dementia (n = 8), or stroke (n = 3). The most commonly employed pain measure was a single-item dichotomous question about pain (n = 16), followed by a visual numeric or visual analog scale (n = 11). Nine studies (five randomized controlled trials) reported on five caregiver pain management interventions, including yoga/exercise programs and caregiver education programs. Existing research on family caregivers' pain offers an important foundation. However, more robust research designs are necessary. We identify possibilities for future studies in addition to opportunities for systematic investigations to support the family caregivers being relied upon to care for the increasing number of older adults.

NURS-04. MUSIC THERAPY WITH CAREGIVERS FOR THOSE WITH PEDIATRIC BRAIN CANCER AND BRAIN TUMORS: A CRITICAL REVIEW OF THE LITERATURE AND RECOMMENDATIONS FOR FUTURE PROGRAMS

Abstract BACKGROUND Caregivers for those with pediatric brain cancer and brain tumors face significant challenges. During the course of treatment, pediatric brain cancer and brain tumor patients face not just the physical consequences of treatments, but the neurological effects as well. METHODS This critical review of the literature examines the effects of Music Therapy on Caregivers, Caregivers for cancer patients, and Caregivers for pediatric cancer patients. A literature review was specifically chosen with the intention of making recommendations for future program planning. Subjects explored include the psychological, physical, and financial impacts of caregiving. Additional concepts include personality traits of Caregivers and multicultural considerations in caregiving. The topics of brain cancer and the use of Music Therapy with patients are also explored. Special attention is given to Music Therapy for Caregivers for those with pediatric brain cancer and brain tumors. Main points under this headline also include Caregiver stressors, similarities and differences in multicultural caregiving, and the limited research available to Caregivers. RESULTS At the time the literature review, no research had been conducted in the area of Music Therapy and Caregivers for pediatric brain cancer and primary brain tumors. Music Therapy was proven, however, to be a significant non-pharmaceutical intervention for several areas, including anxiety and pain management. CONCLUSION The conclusion drawn was that more research is needed with Music Therapy and this particular population. Additionally, a basic framework for a Music Therapy program for Caregivers for those with pediatric brain cancer and brain tumors has been provided with recommendations on the expansion of the program.

Management of acute and chronic anal pain

Anal pain can be acute (most commonly related to anal fissure, perianal abcess or fistula, perianal vein thrombosis) or chronic (functional or neuropathic) including levator ani syndrome, proctalgia fugax, pudendal nevralgia and coccygodynia. History and clinical examination are keys to diagnose acute causes. Diagnosis of chronic anal pain on the other hand is more challenging and based on thorough history and analysis of symptoms. The aim of this article is to discuss the main etiologies and treatments of acute and chronic anal pain, including an update on the management and treatment of hemorrhoidal disease and postoperative pain management.

Burden of chronic pain among adult pastoralists in Ethiopia: a cross-sectional household survey.

Chronic pain is a major global health problem. Untreated pain causes particular suffering in marginalized communities. Most studies investigating chronic pain in sub-Saharan Africa stem from South Africa and Nigeria. Pastoralists are particularly underrepresented in pain research. The main objective of this study is to investigate the burden of chronic pain in adult pastoralists in the Somali Regional State of Ethiopia. We conducted a cross-sectional household survey among adult pastoralists (aged 18 years or older, N = 299) by face-to-face interviews. To randomly select households, we applied GPS-based household localization and recruitment. Chronic pain was self-reported by 17.0% (95% CI: 10.8-25.7) of male and 34.7% (95% CI: 28.4-41.5) of female adult pastoralists. The prevalence of chronic pain increased with age from 5.4% (95% CI: 0.8-30.1; 18-34 years) to 27.1% (95% CI: 15.1-43.7; 35-54 years) to 69.1% (95% CI: 53.7-81.1; 55 years and older). The body sites most commonly affected among those with chronic pain were knees (37.2%), followed by lower back (33.7%) and head (23.3%). The data for the first time provide insights into the burden of chronic pain among Somali pastoralists and reveal associated risk factors. The results support the planning of locally adapted health interventions for pastoralist-specific pain management considering the effects of chronic pain on pastoralists' daily lives.

The role of shared decision-making in cancer pain management: Insights from a systematic review.

e24078 Background: Effective pain management in cancer care is crucial for patient quality of life. Shared decision-making (SDM) interventions are increasingly recognized for their potential to improve patient outcomes by facilitating patient engagement in care decisions. This systematic review synthesizes evidence on the impact of SDM interventions in cancer pain management. Methods: This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We conducted a comprehensive search across multiple databases, including PubMed, EMBASE, Scopus, CINAHL, PsycINFO, Web of Science, and the Cochrane Library. The search also extended to grey literature sources such as conference proceedings, dissertations, and unpublished reports to ensure a thorough coverage of the subject matter. Our search strategy employed a combination of MeSH terms and keywords related to 'decision making,' 'patient participation,' 'pain management,' and 'cancer.' This strategy was tailored to each database's unique syntax and search operators. Results: Ten studies, including six pilot and feasibility studies and four randomized controlled trials (RCTs) and Preintervention-Postintervention studies, were systematically reviewed. The interventions implemented diverse SDM strategies ranging from digital tools and personalized education to clinical decision support systems, targeting key aspects of pain management and patient-provider communication. Frequent intervention components included patient-reported outcome dashboards, symptom management support, and educational resources for pain management. The Tailored Education and Coaching (TEC) intervention notably increased pain-specific patient communication by 31%, while the PAINRelieveIt intervention did not significantly impact analgesic adherence but effectively reduced pain misconceptions among caregivers. Some interventions, like the Carevive CPS, showed high patient involvement in SDM (94.1%) and compliance with quality oncology practice initiative metrics (98%). However, the effectiveness of these interventions varied, with some showing no significant impact on primary pain outcomes. The variability in measured outcomes such as pain intensity, analgesic adherence, and patient satisfaction indicates a context-dependent effectiveness of SDM interventions, highlighting the importance of personalized approaches and the role of implementation strategies in influencing patient engagement and intervention success. Conclusions: SDM interventions in cancer pain management are diverse in structure and impact. Some interventions show promise in improving communication and reducing misconceptions, but their direct effect on pain outcomes varies.

Multidisciplinary PAIN management features of pediatric oncology patients in a pediatric cancer center in Turkiye: A developing country experience.

e22002 Background: Pain is one of the most important problems that affects more than half of cancer patients at any stage of the disease and disrupts the quality of life of patients. The aim should be to relieve pain as soon as possible and prevent its recurrence. In this study, we aimed to evaluate the clinical characteristics of our patients who were followed up with a diagnosis of cancer in our clinic and whose pain management was planned in a multidisciplinary manner with the department of Algology. The clinic where the study was conducted is the reference center of a middle income developing country. Therefore, the data obtained will represent the characteristics of developing countries. Methods: In this retrospective descriptive study, patients followed up with diagnosis of cancer at Ankara University Faculty of Medicine, Department of Pediatric Oncology between 2018 and 2023 and consulted to Department of Algology for pain management were included. Patients whose file information could not be accessed from the hospital information system were excluded from the study. Demographic and clinical parameters of the patients were recorded. The data were evaluated with descriptive statistical methods appropriate to distribution. Results: A total of 33 patients, 19 girls and 14 boys, aged between 2.2 and 23.5 (median 14.4) were evaluated in the study. For each case, a median of 2 (1-16) consultations were made. The most frequent cancer diagnosis was bone tumors with 42% (n:14). Nociceptive pain was present in 25 of the patients, nociceptive and neuropathic pain were present together in 8 patients. It was determined that the most commonly used treatment for pain management was paracetamol, which was used in all patients. Other agents used, in order of frequency: Fentanyl in 19 (57.6%) of the patients, NSAID in 13 (39.4%), gabapentin in 9 (27.3%), oxycodone in 12 (36.4%), 7 (3%) 21.2) were tramadol, 4 (12.5%) were morphine, and 1 (3%) was codeine-paracetamol. Intravenous patient-controlled analgesia (PCA) was used in one patient. Side effects were observed in 3 patients. Fentanyl-related constipation was observed in 1 patient, fentanyl-related globe vesicale was observed in 1 patient, and thrombocytopenia was observed in 1 patient due to gabapentin. Conclusions: Pain is an important factor affecting the quality of life and treatment compliance of children with cancer. Therefore, it is important to ensure effective treatment and to raise the awareness of physicians and care providers by keeping it constantly on the agenda especially in developing countries. Prospective studies will be most useful guide for clinicians.

Pilot study of early integration of interventional pain management for patients with chronic cancer pain.

e24080 Background: Pain is a common, distressing, and costly complication of cancer. Treatment guidelines recommend consideration of interventional pain procedures in addition to pharmacotherapy, yet they are underutilized and often only considered for refractory pain despite high-dose opioids. We examined the feasibility of early integration of interventional pain management among ambulatory patients with chronic cancer pain. Methods: This single arm pilot feasibility study recruited patients from outpatient clinics at the Dana-Farber Cancer Institute. Eligible patients had metastatic or locally advanced solid tumors, persistent pain secondary to cancer/cancer treatment, average pain rating of 4 or higher (0-10 scale), and prognosis &gt; 6 months. Patients could not be taking more than 200 oral morphine equivalents per day. Patients were systematically referred to an interventional pain specialist for consideration of pain procedures, with monthly visits for 4 months. Measures of feasibility included the proportion of patients seen by the pain specialist within 4 weeks, and the proportion undergoing pain procedures. Patients completed surveys at baseline, 2 and 4 months; using the Consumer Assessment of Healthcare Providers and Systems (CAHPS), patients rated their satisfaction with pain clinic (range 0-10), and how often the pain doctor treated them with courtesy and respect, listened carefully, and explained things in a way they could understand (range 1-4, higher scores better). Among those undergoing procedures, patients indicated the percent pain relief they had from the procedure. Results: Between May 2022 and October 2023, 30 patients were enrolled (4 remain on study); mean age, 59.5, 50% male, with a variety of solid tumors; baseline “average pain” and “worst pain” scores were 4.3( SD,1.2) and 6.5( SD,1.6). All but one patient (96.7%) was seen in the pain clinic within four weeks; 57% (n = 17) received one or more pain procedure, with 20% (n = 6) undergoing repeat procedures. The most common procedures were neural blockade (8), celiac plexus neurolysis (n = 4), trigger point injection (n = 3), and epidural steroid injection (n = 3). Among patients receiving a procedure, the median percentage relief was 65% (IQR:30,80). Patients rated the quality of care from the pain clinic highly, with a mean score of 8.6( SD,1.6); and were satisfied with their pain physicians with a mean rating of 3.8( SD,0.4) on treating with respect, 3.7( SD,0.6) for listening, and 3.6( SD,0.6) for explaining. Conclusions: In this study of patients with cancer pain, systematic referral to interventional pain management specialists was feasible, and led to most patients receiving a pain procedure. Patients were satisfied with their pain care and reported meaningful relief of symptoms. Further study is needed to examine whether early integration of interventional pain management improves pain control. Clinical trial information: NCT05366413 .

Safety and Preliminary Effectiveness of Lateral Transiliac Sacroiliac Joint Fusion by Interventional Pain Physicians: A Retrospective Analysis.

Minimally invasive sacroiliac (SI) joint fusion has become the mainstay treatment for chronic refractory sacroiliac joint dysfunction. Multiple procedures are now available including transfixing procedures with implants placed in the lateral or posterolateral transiliac trajectories, and intra-articular procedures with devices and/or allograft placed via a dorsal approach. To date, the published literature on the lateral approach has been primarily by surgeons. This retrospective chart review aims to evaluate the safety and preliminary effectiveness when the procedure is performed by physicians trained in interventional pain management. Retrospective analysis of patients who underwent lateral SI joint fusion using a lateral transiliac approach between December 2022 and September 2023 by a single physician. Data on demographics, perioperative details, complications, and postoperative outcomes were collected and analyzed. The study was reviewed by WCG IRB and received an exemption authorization. Medical charts were reviewed for the first 49 consecutive cases performed. Mean (SD, range) age was 64 (11, 34-83), BMI was 32.5 (8.4), 59% were female, 35% were smokers, and 82% were on opioids at baseline. Mean (SD) operative time was 40 (11) minutes and all procedures were performed at an ambulatory surgery center under monitored anesthesia care. No device- or procedure-related complications occurred. Mean follow up was 175 days; Mean (SD) baseline reported pain was 9 (1.5) on a 0-10 numerical rating scale. At follow up, 88% of the patients reported ≥50% pain relief. Six patients who reported 0% relief suffer from multiple pain generators and are on long term opioids. Results of this single center experience support the safety of lateral SI joint fusion using a threaded implant when performed by interventional pain management physicians. However, further prospective studies with larger sample sizes and longer follow-ups are warranted to validate these findings.

Chitosan Nanoparticles for Intranasal Drug Delivery.

This manuscript explores the use of nanostructured chitosan for intranasal drug delivery, targeting improved therapeutic outcomes in neurodegenerative diseases, psychiatric care, pain management, vaccination, and diabetes treatment. Chitosan nanoparticles are shown to enhance brain delivery, improve bioavailability, and minimize systemic side effects by facilitating drug transport across the blood-brain barrier. Despite substantial advancements in targeted delivery and vaccine efficacy, challenges remain in scalability, regulatory approval, and transitioning from preclinical studies to clinical applications. The future of chitosan-based nanomedicines hinges on advancing clinical trials, fostering interdisciplinary collaboration, and innovating in nanoparticle design to overcome these hurdles and realize their therapeutic potential.

The Anterior Branch of the Medial Femoral Cutaneous Nerve Innervates Cutaneous and Deep Surgical Incisions in Total Knee Arthroplasty.

Background/Objectives: The intermediate femoral cutaneous nerve (IFCN), the saphenous nerve, and the medial femoral cutaneous nerve (MFCN) innervate the skin of the anteromedial knee region. However, it is unknown whether the MFCN has a deeper innervation. This would be relevant for total knee arthroplasty (TKA) that intersects deeper anteromedial genicular tissue layers. Primary aim: to investigate deeper innervation of the anterior and posterior MFCN branches (MFCN-A and MFCN-P). Secondary aim: to investigate MFCN innervation of the skin covering the anteromedial knee area and medial parapatellar arthrotomy used for TKA. Methods: This study consists of (1) a dissection study and (2) unpublished data and post hoc analysis from a randomized controlled double-blinded volunteer trial (EudraCT number: 2020-004942-12). All volunteers received bilateral active IFCN blocks (nerve block round 1) and saphenous nerve blocks (nerve block round 2). In nerve block round 3, all volunteers were allocated to a selective MFCN-A block. Results: (1) The MFCN-A consistently innervated deeper structures in the anteromedial knee region in all dissected specimens. No deep innervation from the MFCN-P was observed. (2) Sixteen out of nineteen volunteers had an unanesthetized skin gap in the anteromedial knee area and eleven out of the nineteen volunteers had an unanesthetized gap on the skin covering the medial parapatellar arthrotomy before the active MFCN-A block. The anteromedial knee area and medial parapatellar arthrotomy was completely anesthetized after the MFCN-A block in 75% and 82% of cases, respectively. Conclusions: The MFCN-A shows consistent deep innervation in the anteromedial knee region and the area of MFCN-A innervation overlaps the skin area covering the medial parapatellar arthrotomy. Further trials are mandated to investigate whether an MFCN-A block translates into a clinical effect on postoperative pain after total knee arthroplasty or can be used for diagnosis and interventional pain management for chronic neuropathic pain due to damage to the MFCN-A during surgery.

Development of a nurse navigation program for cancer pain

ObjectiveCancer pain significantly impacts the overall quality of life of cancer patients, necessitating proactive management. The manifestations of cancer pain vary individually and require tailored interventions to address each patient's unique characteristics. Therefore, this study aims to develop a nurse navigation program for cancer pain (NNP-CP) tailored to the needs of cancer patients requiring pain control, aiming to establish evidence-based clinical nursing practices and promote effective cancer pain management. MethodsThis study is a methodological research into developing a pain management program led by nurses for cancer patients requiring pain control, based on a professional navigation framework. The development of the program relied on three out of the five stages of the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. ResultsA literature review was conducted to select the content and rationale to be included in the intervention program. Publications within the last 10 years in English or Korean were identified and screened based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 literature selection flow, 17 articles were included. Standardized information regarding cancer pain control was based on the 7th edition of 'Cancer Pain Management Guidelines'. The initial draft of the pain management intervention program was developed by organizing and structuring the derived content based on the professional navigation framework. Subsequently, the final intervention program was confirmed through the review by six clinical experts specializing in cancer pain. ConclusionsCancer pain is a significant factor that profoundly influences the quality of life and survival duration of cancer patients. While appropriate management methods offer the prospect of control, insufficient intervention is the current reality. Through the pain management intervention program based on the expert navigation framework that promotes continuity of care and empowers the recipients, this study anticipates not only pain reduction in cancer patients but also an enhancement in their quality of life.

Systematic Structure-Activity Relationship Study of Nalfurafine Analogues toward Development of Potentially Nonaddictive Pain Management Treatments.

Despite the availability of numerous pain medications, the current array of Food and Drug Administration-approved options falls short in adequately addressing pain states for numerous patients and consequently worsens the opioid crisis. Thus, it is imperative for basic research to develop novel and nonaddictive pain medications. Toward addressing this clinical goal, nalfurafine (NLF) was chosen as a lead and its structure-activity relationship (SAR) systematically studied through design, syntheses, and in vivo characterization of 24 analogues. Two analogues, 21 and 23, showed longer durations of action than NLF in a warm-water tail immersion assay, produced in vivo effects primarily mediated by KOR and DOR, penetrated the blood-brain barrier, and did not function as reinforcers. Additionally, 21 produced fewer sedative effects than NLF. Taken together, these results aid the understanding of NLF SAR and provide insights for future endeavors in developing novel nonaddictive therapeutics to treat pain.

Physical therapy for survivors of torture: A scoping review.

Torture can result in impaired functional mobility, reduced quality of life, and persistent pain. Physical therapy (PT) is recommended for holistic care of survivors of torture (SOT), however there are limited evidenced-based guidelines. We conducted a scoping review to identify and describe the approach and gaps in knowledge around the PT treatment of SOT. We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Re-views. Nine databases were searched. Eligible sources involved PT treatment for SOT. Interventions were categorized into themes based on recommendations from the Physiotherapy and Refugees Edu-cation Project: 1) trauma-informed care, 2) body-awareness and empowerment, 3) pain management. The final analysis included 15 sources. Eight sources included all three themes; three of these eight sources were research studies examining outcomes following the PT intervention. While out-comes of these studies were significant for improvement among the PT groups, results must be taken cautiously due to methodological limitations of the trials. Studies assessing treatment that included only one theme resulted in no differences between the control and intervention groups. We describe the scope of the literature regarding PT for SOT. A trauma-informed PT approach, co-ordinated with pain management, and body-awareness and empowerment interventions may address the complex needs of survivors. However, rigorous studies of this three-themed approach are lacking. As SOT seek medical services, healthcare providers must be prepared to care for these vulnerable people. Physical therapists are encouraged to utilize a holistic approach, and to examine outcomes of this approach for SOT.

An evidence-based breathing exercise intervention for chronic pain management in breast cancer survivors: A phase II randomized controlled trial

ObjectiveExplore the preliminary effects of a breathing exercise (BE) intervention on chronic pain among breast cancer survivors. MethodsThis two-parallel-arm, open-label pilot randomized controlled trial recruited 72 breast cancer survivors who were randomly allocated to either the control or intervention group (n = 36 each). Both groups received usual care and a pain information booklet, while the intervention group received 4 weeks of additional BE. The primary clinical outcome was measured using the Brief Pain Inventory (BPI), with secondary clinical outcomes measured by the Hospital Anxiety and Depression Scale (HADS), Quality of Life Patient/Cancer Survivor Version in Chinese (QOLCSV-C), and Functional Assessment of Cancer Therapy- Breast (FACT-B) immediately post-intervention and at 4-week follow-up. Both adjusted and unadjusted Generalized Estimating Equation models were utilized to assess the BE's potential effects, with safety assessed through participant self-report. ResultsSixty-eight participants completed the study. Statistical significance was observed in BPI in both adjusted and unadjusted models at post-intervention and follow-up (p < 0.05). BE demonstrated positive effects on anxiety, depression and quality of life improvement across all measures and timepoints in both adjusted and unadjusted models (p < 0.05). The effect sizes were smaller in the adjusted model. Three mild transient discomforts were reported associated with BE practice including dizziness, tiredness and yawning, without requirement of medical treatment. No severe adverse events occurred. ConclusionThis BE intervention appears effective in alleviating chronic pain, anxiety and depression, and improving quality of life for breast cancer survivors. Fully powered large-scale studies are required to confirm its effects.
