Chronic pain

SUMOylation is a post-translational modification that attaches a small ubiquitin-like modifier (SUMO) group to a target protein via SUMO ligases, while deSUMOylation refers to the removal of this SUMO group by sentrin-specific proteases (SENPs). Although the functions of these processes have been well described in the nucleus, the role of SUMOylation and deSUMOylation in regulating ion channels is emerging as a novel area of study. Despite this, their contributions to pain signaling remain less clear. Therefore, this review consolidates the current evidence on the link(s) between SUMOylation, deSUMOylation, and pain, with a specific focus on ion channels expressed in the sensory system...

Introduction Robot-assisted radical prostatectomy (RARP) provides much quicker recovery for men than open prostatectomy. In most centers, discharge is planned the morning after surgery. However, after several years, we observed that no routine intervention was required for a majority of men over the first evening. Here, we detail our institution's outcomes for multiport RARP (MP-RARP) with same-day discharge (SDD). Methods After excluding patients with single-port RARP (n=25) and overnight stays (n=30), data from 224 patients (n=224/279, 88...

OBJECTIVE: To investigate the effectiveness of a Pilates exercise program compared with home-based exercises in individuals with chronic non-specific low back pain. DESIGN: A randomised controlled trial with a six-month follow-up. SETTING: Rehabilitation clinic. PARTICIPANTS: One hundred and forty-five individuals (18-50 years of age) with low back pain for ≥ 12 consecutive weeks were enrolled and randomly allocated to either Pilates ( n  = 72) or home-based exercise groups ( n  = 73)...

Cervical pain has been linked to increased motor unit activity, potentially associated with the initiation and progression of chronic neck pain. Therefore, this study aimed to compare the time-course changes in cervical superficial muscle activation patterns among dental students with and without neck pain throughout their initial semester of clinical training. We used an online Nordic Musculoskeletal Questionnaire for group allocation between neck pain (NP) ( n = 21) and control group (CG) ( n = 23). Surface electromyography (sEMG) of the sternocleidomastoid and upper bilateral trapezius was recorded before starting their clinical practice and after their first semester while performing a cranio-cervical flexion test (CCFT) in five increasing levels between 22 mmHg and 30 mmHg...

BACKGROUND/OBJECTIVES: Comprehensive conservative management (CCM) is a viable treatment option for elderly patients with end-stage kidney disease (ESKD). However, it involves a significant change in dietary habits, such as adopting a low-protein diet. Therefore, it is crucial to understand its impact on the patient's quality of life (QoL), particularly when compared to hemodialysis (HD). The study aims to evaluate the differences in the QoL between patients undergoing CCM and HD. METHODS: The study included 50 patients over 75 with ESKD, with 25 patients in the CCM group and 25 in the HD group...

This narrative review provides an overview of current knowledge on the impact of nutritional strategies on chronic craniofacial pain associated with temporomandibular disorders (TMDs). Individuals experiencing painful TMDs alter their dietary habits, avoiding certain foods, possibly due to chewing difficulties, which might lead to nutrient deficiencies. Our literature investigation revealed that the causal links between nutritional changes and craniofacial pain remain unclear. However, clinical and preclinical studies suggest that nutraceuticals, including vitamins, minerals, polyphenols, omega-3 fatty acids, isoprenoids, carotenoids, lectins, polysaccharides, glucosamines, and palmitoylethanolamides, could have beneficial effects on managing TMDs...

Background/Objectives : Cervical facet joint syndrome (CFJS) is a frequent cause of neck pain and motor disability. Among the available therapies for CFJS, ultrasound (US)-guided injections are becoming more and more widespread, but the evidence about their accuracy and effectiveness is still debated in the scientific literature. The aim of this systematic review is to assess efficacy, accuracy and feasibility of US-guided cervical facet injections for the related chronic neck pain treatment. Methods : This review was conducted following the preferred reporting items for systematic reviews and meta-analysis 2020 (PRISMA) statement guidelines...

Wounds in diabetic patients with peripheral arterial disease (PAD) may be poorly responsive to revascularization and conventional therapies. Background/Objective : This study's objective is to analyze the results of regenerative cell therapy with peripheral blood mononuclear cells (PBMNCs) as an adjuvant to revascularization. Methods: This study is based on 168 patients treated with endovascular revascularization below the knee plus three PBMNC implants. The follow-up included clinical outcomes at 1-2-3-6 and 12 months based on amputations, wound healing, pain, and TcPO2...

Background: Epidemiological data indicate that low back pain (LBP) affected 619 million people globally in 2020, representing a significant health and economic burden. Additionally, chronic LBP (cLBP) strongly impairs quality of life and leads to disability and premature retirement, thus emphasizing the need for providing deeper insight into the factors that affect treatment outcomes and for offering thorough guidance for the assessment and management of this condition. Taking into consideration the rising prevalence of cLBP and the knowledge gap referring to the overall health benefits of balneotherapy (BT), the aim of this study was to assess the effects of BT on functional status, quality of life, and psychological symptoms in patients with cLBP...

Background/Objectives : To investigate if intra-articular biomarkers relate to peripheral and central sensitization in patients with late-stage knee osteoarthritis (KOA). Methods : A total of 17 (6M, 11F) patients (aged 69 ± 10 years) were assessed for peripheral (pressure pain thresholds (PPT)) and central (temporal summation (TS) and conditioned pain modulation (CPM)) sensitization the day before total knee arthroplasty. Synovial fluid was collected during surgery and assayed for IL-6, IL-8, IL-10, TNF-α, CXCL-10, BDNF, NGF, CCL2, CCL5, VEGF, IL-1RI, MMP-1, MMP-7, IL-1β, and CXCL-9...

Background: Chronic pain (CP) patients frequently feel misunderstood and experience a lack of support. This led to the creation of support telephone lines in some countries. However, there is no scientific data grounding their development or evaluating their performance. Almost 37% of the Portuguese adult population suffers from CP, with great costs for patients and the healthcare system. Methods : To determine the viability of a support line for CP in Portugal, a qualitative study was designed, and online focus group meetings, with patients and healthcare professionals, were conducted...

The global cases of knee osteoarthritis (KOA) are projected to increase by 74.9% by 2050. Currently, over half of patients remain dissatisfied with their pain relief. This review addresses unmet needs for moderate-to-severe KOA pain; it offers evidence and insights for improved management. Italian experts from the fields of rheumatology, physical medicine and rehabilitation, orthopedics, primary care, and pain therapy have identified several key issues. They emphasized the need for standardized care protocols to address inconsistencies in patient management across different specialties...

Background: With limited pharmacological interventions, post-COVID-19 condition is a clinical challenge, and supplementary therapies are essential for symptom relief and enhancing quality of life (QoL). In our prospective observational study, we aimed to evaluate the impact of Salus per aquam (Spa) therapy on post-COVID-19 symptoms and QoL in individuals who suffer from chronic joint, musculoskeletal, skin, and/or respiratory conditions. Methods: A total of 159 individuals undergoing Spa therapy were enrolled, and 78 of them had post-COVID-19 symptoms, assessed using Visual Analogue Scale (VAS) and modified British Medical Research Council Questionnaire (mMRC-DS scales), as well as the Short Form 36 Health Status Survey (SF-36) questionnaire for QoL...

Background: Endometriosis is known to be a common chronic disease that often affects the quality of life of patients. Especially for deep endometriosis (DE), the most challenging form of the disease, surgery remains an important component of treatment. However, long-term outcomes after surgery are poorly studied. Therefore, we aimed to evaluate the postoperative clinical course of women with DE who underwent surgery, particularly with regard to pain relief, fertility, and re-operations. Methods: Thus, women who underwent surgical treatment for DE between 2005 and 2015 were included in this retrospective questionnaire-based analysis...

Background/Objectives : Terminal ileitis (TI) is often identified on CT scans in emergency settings. Diagnosing Crohn's disease (CD) as a cause of TI is crucial due to its significant long-term implications. This study aimed to differentiate CD from other causes of acute TI and develop a predictive model for CD diagnosis. Methods : A retrospective case-control study was conducted at Shamir Medical Center including adults diagnosed with acute TI from January 2012 to December 2020. Patients with a history of inflammatory bowel disease or prior intestinal surgery were excluded...

Background/Objectives: There is emerging evidence that task-specific pain-related psychological measures may better predict movement behaviour in chronic low back pain (CLBP) than general pain-related psychological measures. Currently, little is known regarding the prediction of movement duration and movement velocity. Methods : Baseline data from a previously published randomized controlled trial were used (clinicaltrials.gov NCT02773160). Fifty-five patients with CLBP and 54 pain-free persons performed a lifting task while kinematic measurements were obtained to calculate movement velocity of the L1 vertebra, S1 vertebra, and the lumbar spine, as well as the time to complete the lifting task...
