Pulmonary involvement in newly diagnosed and untreated rheumatoid arthritis and psoriatic arthritis: a prospective longitudinal study

ObjectivesTo longitudinally assesses pulmonary involvement in newly diagnosed rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients over a 12-months follow-up. To identify biomarkers and establish a diagnostic algorithm for monitoring pulmonary changes.MethodsNewly diagnosed RA and PsA patients were examined with clinical and laboratory assessments, pulmonary function tests (PFT), and chest radiography (CXR) at three-months intervals for one year.ResultsThe study enrolled 50 patients (26 RA, 24 PsA) and 26 controls. At baseline, 37.0% of arthritis patients (50.0% RA, 22.7% PsA) exhibited radiographic pulmonary involvement, with 64.7% being asymptomatic. No association was observed between CXR and PFTs. Reduced pathological breathing width was noted in 64.0% of patients (RA 69.2%, PsA 58.3%) and 23.1% of controls (p < .001). Thoracic excursion and lung auscultation showed no differences. During follow-up, PFT and physical examination findings remained stable. Mean CRP levels significantly decreased in RA patients from 23.5 mg/l (± 33.6; 95% CI: 9.9–37.1) to 2.7 mg/L (± 3.4; 95% CI: 1.0-4.3), and in PsA patients from 13.3 mg/L (± 18.0; 95% CI: 5.7–20.9) to 8.1 mg/L (± 16.2; 95% CI: 0.1–16.2) (p < .001). Additionally, significant reductions in disease activity scores and improvements in six-minute walking distance were observed (p < .001). No associations were identified between PFT outcomes, disease activity, or rheumatological medications throughout the disease course.ConclusionOur study underscores the prevalence of significant, predominantly asymptomatic pulmonary involvement in newly diagnosed RA and PsA patients. The lack of correlation between pulmonary function, disease activity, and medication during disease progression suggests that reducing arthritic disease activity does not necessarily mitigate the risk or severity of pulmonary involvement. Finally, our finding underscore the need for more sensitive biomarkers and optimized monitoring strategies.

Abstract 4143239: Extracorporeal Shockwave Therapy Improves Physical Outcomes and Quality of Life In Patients With Symptomatic Peripheral Arterial Disease: Results from a Meta-analysis of Randomized Controlled Trials

Introduction: Extracorporeal shockwave therapy (ESWT) is a non-invasive procedure that may be useful to treat symptomatic peripheral arterial disease (PAD). Trials comparing ESWT with control groups have shown promising results. Methods: PubMed, Cochrane, EMBASE, and Google Scholar were searched for randomized controlled trials reporting the efficacy of extracorporeal shockwave therapy versus control in patients with symptomatic PAD. Data from eligible studies was analyzed using the Review Manager 5.4 software. Mean difference (MD) and 95% Confidence intervals (CI) were calculated for continuous outcomes. Inverse variance method and a random effects model were used for pooled estimates. A p-value &lt; 0.05 (Z-test) was considered significant. Results: 5 randomized controlled trials with 264 patients were included in our analysis. A significant increase in the mean walking distance (MD: 54.13, 95% CI 9.34 to 98.92, p=0.02), pain-free walking distance (MD: 54.13, 95% CI 14.19, 57.88, p= 0.001), SF-36 physical component summary (MD: 11.97, 95% CI 0.26 to 23.69, p=0.05), EQ-5D-3L index score (MD; 0.08, 95% CI: 0.00 to 0.15, p=0.05) and VascuQoL index ((MD: 0.48, 95% CI 0.03 to 0.92, p= 0.04) was seen with ESWT. A slightly higher ankle brachial pressure index was seen in the control group (MD: -0.01, 95% CI: -0.02 to -0.00, p=0.04). There was no difference in SF-36 physical functioning domain score (MD: 18.58, 95% CI: -0.29 to 37.45, p=0.05) and SF-36 bodily pain score (MD: 9.17, 95% CI: -2.885 to 21.19, p=0.13). Conclusions: There was significant improvement in walking distances, exertional symptoms, and quality of life with ESWT. However, ESWT did not translate to an increase in post-treatment ankle-brachial index which was slightly higher in the control group. There is a need for larger randomized controlled trials to substantiate the efficacy of ESWT in treating symptomatic PAD.

A new management strategy in reopening laminectomies for cases with spinal canal stenosis

Background While a laminectomy is often mandated for spinal canal stenosis, foraminal stenosis may account for pain and functional limitations instead of central canal issues. Targeted treatment directed at this specific region may enhance patient outcomes. Methods Retrospective observational study of a total of 30 patients with previous decompression laminectomies for lumbar spinal canal stenosis were operated upon for foraminotomies from November 2012 to November 2018. The surgeries were clinically done, and EMG-confirmed nerve root compressions were treated with exact decompression techniques according to the anatomy and pathology in each case. Additionally, a systematic review followed PRISMA guidelines was conducted, utilizing Scopus and PubMed databases to identify studies on reoperation rates after decompression with or without fusion in lumbar spinal stenosis. Results The results were fearsome post-operatively, trying significant improvement in pain, functional status, and walking distance. Pain reduction was achieved in 80% of patients by an increase in the Carnovsky rating scale with evidence of improved pain reduction and walking endurance; this points to minimal resulting complications of one complete case of foot drop and three infective cases managed conservatively. It was shown in the systematic review that fusion surgeries lowered the rates of reoperations at the index level but increased those for adjacent segment reoperations, while decompression alone had higher index-level reoperation rates due to recurrent stenosis. Conclusion Most of the emphasis on foraminal stenosis, rather than traditional laminectomies, significantly reduces postoperative pain and improves functional outcomes. This strategy brings a promising alternative to the management of recurrent symptoms in patients with lumbar spinal canal stenosis.

Effect of Perioperative Inhaled Tiotropium for patients with chronic Obstructive Pulmonary disease in Esophageal cancer surgery (EPITOPE): an open-label, randomized, parallel-group pilot study.

Chronic obstructive pulmonary disease (COPD) is a risk factor for pneumonia following esophagectomy. This study aimed to investigate the efficacy of perioperative inhaled tiotropium in patients with COPD undergoing esophagectomy. This open-label, randomized controlled trial randomly assigned 32 patients with COPD undergoing esophagectomy to conventional management or addition of tiotropium inhalation. The intervention group received tiotropium from two weeks before esophagectomy until the final evaluation one month after esophagectomy. The primary outcome was the incidence of pneumonia within 30 postoperative days. We also assessed the changes and the percentages from baseline in pulmonary function and walking distance of the incremental shuttle walking test to just before esophagectomy and final evaluation. Enrolled patients were randomly assigned to the control group (n = 18) and the intervention group (n = 14). Pneumonia was recorded in 4 (28.6%) and 5 (27.8%) patients in the intervention and control groups, respectively (risk difference: 0.8%, 95% confidence interval: - 30.6 to 32.2). The intervention group demonstrated a significant improvement in pulmonary function and walking distance preoperatively. Further, the pulmonary function test was significantly better preoperatively in the intervention group than in the control group. Postoperatively, pulmonary function deterioration was more significant in the control group than in the intervention group. Preoperative tiotropium inhalation significantly improved pulmonary function and exercise tolerance in patients with COPD undergoing esophagectomy. The perioperative tiotropium did not reduce pneumonia after esophagectomy, but it may contribute to patient recovery by reducing postoperative pulmonary function deterioration.

Real-time auditory feedback for improving gait and walking in people with Parkinson’s disease: a pilot and feasibility trial

BackgroundTechnology is poised to bridge the gap between demand for therapies to improve gait in people with Parkinson’s and available resources. A wearable sensor, Heel2Toe™, a small device that attaches to the side of the shoe and gives a sound each time the person starts their step with a strong heel strike, has been developed and pre-tested by a team at McGill University. The objective of this study was to estimate feasibility and efficacy potential of the Heel2Toe™ sensor in changing walking capacity and gait pattern in people with Parkinson’s.MethodsA pilot study was carried out involving 27 people with Parkinson’s randomized 2:1 to train with the Heel2Toe[TM] sensor and or to train with recommendations from a gait-related workbook.ResultsA total of 21 completed the 3-month evaluation, 14 trained with the Heel2Toe[TM] sensor, and 7 trained with the workbook. Thirteen of 14 people in the Heel2Toe group improved over measurement error on the primary outcome, the 6-Minute Walk Test, (mean change 66.4 m) and 0 of the 7 in the Workbook group (mean change − 19.4 m): 4 of 14 in the Heel2Toe group made reliable change and 0 of 7 in the Workbook group. Improvements in walking distance were accompanied by improvements in gait quality. Forty percent of participants in the intervention group were strongly satisfied with their technology experience and an additional 37% were satisfied.ConclusionsDespite some technological difficulties, feasibility and efficacy potential of the Heel2Toe sensor in improving gait in people with Parkinson’s was supported.

Balloon Pulmonary Angioplasty for Chronic Thromboembolic Pulmonary Disease: Success Rate and Complications among Different Patient Populations.

Balloon pulmonary angioplasty (BPA) is an effective intervention for patients with chronic thromboembolic pulmonary disease (CTEPD). We aimed to identify the patient group with a low success rate or high complication rate of BPA, which is still unclear. Both CTEPD patients with or without pulmonary hypertension (CTEPH and NoPH-CTEPD) were included. CTEPH patients were divided into groups with or without pulmonary endarterectomy (PEA-CTEPH and NoPEA-CTEPH). The efficacy and safety of BPA were compared among the groups. There were 450, 66, and 41 sessions in the NoPEA-CTEPH, PEA-CTEPH, and NoPH-CTEPD groups, respectively. The success rate (≥1 degree improvement in flow grade) in the PEA-CTEPH group was 94.5%, significantly lower than that in the NoPEA-CTEPH (97.1%) and NoPH-CTEPD (98.4%) groups (p = 0.014). The percentage of complete flow recovery in treated vessels was also lower in PEA-CTEPH group. BPA-related complication rate in NoPEA-CTEPH, PEA-CTEPH, and NoPH-CTEPD patients was 6.1%, 6.0%, and 0.0%, respectively (p = 0.309). One BPA-related death occurred (solely in NoPEA-CTEPH). Mean pulmonary artery pressure ≥41.5 mm Hg was a predictor of BPA-related complications. NoPEA-CTEPH patients had more improvement in 6-min walk distance (6MWD, 87 ± 93 m NoPEA-CTEPH vs. 40 ± 43 m PEA-CTEPH vs. 18 ± 20 m NoPH-CTEPD, p = 0.012). BPA was safe and effective for all CTEPD groups with less improvement for the PEA-CTEPH and NoPH-CTEPD groups. The success rate of BPA was lower in the PEA-CTEPH group and the complication rate was lower in the NoPH-CTEPD group. Pre-BPA treatment to lower pulmonary artery pressure should not be overlooked in CTEPD patients.

The influence of aquatic activity on osteoarthritis

© 2024 Medical University of Lublin. This is an open access article distributed under the Creative Commons Attribution-NonComercial-No Derivs licence (http://creativecommons.org/licenses/by-nc-nd/3.0/) Abstract Introduction. In 2020, osteoarthritis (OA) affected up to 595 million people in the world, which is 7% of the population. Three quarters of them are over 55 years old and 60% are women. The pathophysiological basis of degenerative disease is a disturbance in the balance between the processes of formation and degradation of articular cartilage. Additionally, degeneration processes affect other elements of the musculoskeletal system, such as the synovial capsule, ligaments and muscles around the joint. Due to the severe pain, degenerative disease leads to a significant reduction in the quality of life and limited mobility. In the final stage it leads to disability. Arthritis most often involves the knee, hip joints, arms as well as vertebral column. To slow down the degenerative processes and minimize the complications of the disease, effective preventive methods should be implemented as soon as possible. Especially since there is currently no effective drug available for this disease. A popular method of combating pain is aquatic activity. The physical properties of water have a positive effect on the musculoskeletal and nervous systems. This review article assessed the effectiveness of aquatherapy depending on risk factors and the stage of osteoarthritis. Aim. Review and presentation of the current state of knowledge about water exercises on the course of osteoporosis, taking into account groups at risk of degenerative disease. Material and methods. Analysis of the studies available on open access sources at PubMed, Google Scholar, National Library of Medicine and Coachrane. The research was conducted through word analysis key words such as: “arthritis”, „aquatic activity”, „osteoarthritis”. Selection criteria for articles included consideration of their title, abstract, and publication date, with a focus on English-language publications. Conclusion and Results.This article demonstrates the positive impact of water exercises on the course of osteoporosis, as well as their preventive effect. The relationship between hydrotherapy and OA in individual risk groups was presented. Aquatic activity has been shown to be effective in inhibiting degenerative processes, reducing joint stiffness, improving walking distance, and mental condition. Keywords: osteoarthritis, aquatic activity, arthritis, WOMAC, degenerative disease, DALY.

Effect of Pre- and Post-Dialysis Exercise on Functional Capacity Using Portable Ergometer in Chronic Kidney Disease Patients.

To assess whether performing exercises during hemodialysis reduces the risk of developing intradialytic hypotension and enhances exercise capacity in patients with chronic kidney disease. This study included patients aged ≥18 years undergoing hemodialysis. Participants performed exercises using a portable lower extremity ergometer during hemodialysis sessions for 3 weeks. Data regarding walking distance, knee strength, quality of life, fat-free mass, arterial pressure, blood pressure, heart rate, frequency of intradialytic hypotension, fatigue, and duration of hemodialysis were collected and analyzed. Significant improvements in walking distance and knee strength were observed following the implementation of exercise training during hemodialysis. Although there was no significant reduction in the frequency of intradialytic hypotension, a decreasing trend was noted. Other parameters such as quality of life and fatigue did not show significant changes. Using a portable ergometer during hemodialysis improved exercise capacity and knee strength in patients with chronic kidney disease. There was a trend toward reduced intradialytic hypotension, suggesting potential cardiovascular benefits. Further research with larger sample sizes is needed to confirm these findings.

Effect of Arm-Ergometry Versus Treadmill Supervised Exercise on Cardiorespiratory Fitness and Walking Distances in Patients With Peripheral Artery Disease: The ARMEX Randomized Clinical Trial.

To compare arm-ergometry and treadmill supervised exercise training on cardiorespiratory fitness and walking distances in patients with peripheral artery disease (PAD). ARMEX was a single-center, single-blinded, parallel group, non-inferiority trial enrolling symptomatic patients with PAD. Patients were randomized (1:1 ratio) to a 12-wk arm-ergometry (AEx) or standard treadmill (TEx) supervised exercise training protocol. The powered primary end point was the change in peak oxygen uptake (VO 2 ) at 12 wk, measured on a treadmill cardiopulmonary exercise test (CPX). Secondary outcomes included changes in VO 2 at the first ventilatory threshold (VT-1), ventilatory efficiency (ratio of minute ventilation [VE] to carbon dioxide production [VCO 2 ], VE/VCO 2 ), walking distances by CPX and 6-min walking test (6MWT), and self-reported walking limitations. Fifty-six patients (66±8yr; 88% male) were randomized (AEx, n =28; TEx, n =28). At 12 wk, VO 2peak change was not significantly different between groups (0.75 mL/kg/min; 95% CI, -0.94 to 2.44; P =.378), despite a significant increase only in AEx. VO 2 at VT-1 improved in both groups without between-group differences, and VE/VCO 2 slope improved more in AEx. The TEx attained greater improvements in walking distance by CPX (121.08 m; 95% CI, 24.49-217.66; P =.015) and 6MWT (25.08 m; 95% CI, 5.87-44.29; P =.012) and self-perceived walking distance. Arm-ergometry was noninferior to standard treadmill training for VO 2peak , and treadmill training was associated with greater improvements in walking distance. Our data support the use of treadmill as a first-line choice in patients with PAD to enhance walking capacity, but arm-ergometry could be an option in selected patients.

Effects of combining a high-intensity interval training programme with a standard programme on mobility and function in lower limb amputees.

High-energy expenditure during walking is one of the most important limiting factors for lower limb amputees. Although several physical training methods have been proposed to reduce energy expenditure, little is known about the effects of high-intensity interval training in lower limb amputees. This study aimed to test the effects of a 6-week high-intensity interval training protocol in subjects with lower limb amputation on walking distance, physiological cost of walking, and functional mobility. A quasi-experimental pre and post-study included 13 subjects with lower limb amputation. They performed 12 sessions of a high-intensity interval training protocol with a frequency of 2 days/week for 6 weeks. Walking distance, physiological cost of walking, and functional mobility before and after the training protocol were assessed. Walking distance increased from 204.48 to 229.09 m ( P = 0.003), physiological cost of walking decreased from 0.66 to 0.31 beats/m ( P = 0.001), and functional mobility improved from 30.38 to 33.61 points ( P = 0.001). High-intensity interval training improved walking distance, physiological cost of walking, and functional mobility in subjects with lower limb amputation.

Actual and Imagined Music-Cued Gait Training in People with Multiple Sclerosis: A Double-Blind Randomized Parallel Multicenter Trial

Background Actual and imagined cued gait trainings have not been compared in people with multiple sclerosis (MS). Objective To analyze the effects of cued motor imagery (CMI), cued gait training (CGT), and combined CMI and cued gait training (CMI-CGT) on motor, cognitive, and emotional functioning, and health-related quality of life in people with MS. Methods In this double-blind randomized parallel-group multicenter trial, people with MS were randomized (1:1:1) to CMI, CMI-CGT, or CGT for 30 minutes, 4×/week for 4 weeks. Patients practiced at home, using recorded instructions, and supported by ≥6 phone calls. Data were collected at weeks 0, 4, and 13. Co-primary outcomes were walking speed and distance, analyzed by intention-to-treat. Secondary outcomes were global cognitive impairment, anxiety, depression, suicidality, fatigue, HRQoL, motor imagery ability, music-induced motivation, pleasure and arousal, self-efficacy, and cognitive function. Adverse events and falls were continuously monitored. Results Of 1559 screened patients, 132 were randomized: 44 to CMI, 44 to CMI-CGT, and 44 to CGT. None of the interventions demonstrated superiority in influencing walking speed or distance, with negligible effects on walking speed (η2 = 0.019) and distance (η2 = 0.005) observed in the between-group comparison. Improvements in walking speed and walking distance over time corresponded to large effects for CMI, CMI-CGT, and CGT (η2 = 0.348 and η2 = 0.454 respectively). No severe study-related adverse events were reported. Conclusions CMI-GT did not lead to improved walking speed and distance compared with CMI and CGT alone in people with MS. Lack of a true control group represents a study limitation. Trial registration German Clinical Trials Register, DRKS00023978.

Biped Robots Control in Gusty Environments with Adaptive Exploration Based DDPG.

As technology rapidly evolves, the application of bipedal robots in various environments has widely expanded. These robots, compared to their wheeled counterparts, exhibit a greater degree of freedom and a higher complexity in control, making the challenge of maintaining balance and stability under changing wind speeds particularly intricate. Overcoming this challenge is critical as it enables bipedal robots to sustain more stable gaits during outdoor tasks, thereby increasing safety and enhancing operational efficiency in outdoor settings. To transcend the constraints of existing methodologies, this research introduces an adaptive bio-inspired exploration framework for bipedal robots facing wind disturbances, which is based on the Deep Deterministic Policy Gradient (DDPG) approach. This framework allows the robots to perceive their bodily states through wind force inputs and adaptively modify their exploration coefficients. Additionally, to address the convergence challenges posed by sparse rewards, this study incorporates Hindsight Experience Replay (HER) and a reward-reshaping strategy to provide safer and more effective training guidance for the agents. Simulation outcomes reveal that robots utilizing this advanced method can more swiftly explore behaviors that contribute to stability in complex conditions, and demonstrate improvements in training speed and walking distance over traditional DDPG algorithms.

Influence of the sagittal spinal profile type on the long-term outcome of patients with symptomatic lumbar spinal stenosis after microsurgical decompression

OBJECTIVE Microsurgical decompression for patients with symptomatic lumbar spinal stenosis (LSS) has demonstrated long-term improvement concerning pain and function. Nonetheless, a considerable proportion of these patients do not experience satisfactory alleviation of symptoms. Previous studies have not found a direct influence of single sagittal parameters on patient outcomes. However, recent research indicates that a composite of parameters, presented in specific sagittal profile types (SPTs) that were defined by Roussouly and colleagues, may affect these outcomes. This study aims to investigate the impact of SPT on long-term outcomes of patients with LSS following microsurgical decompression. METHODS This study is a prospective clinical observation. Patients with symptomatic LSS, who underwent microsurgical treatment and had long-term follow-up data for at least 36 months, were included. Patients with spinal deformity, fractures, or significant instability were excluded. Outcomes were measured using the numeric rating scale for pain, 36-Item Short Form Health Survey for quality of life, walking distance, Oswestry Disability Index, Roland-Morris Disability Questionnaire, and Odom’s criteria. SPT was determined in blinded fashion by using preoperative long standing radiographs. RESULTS The initial population of this observational study consisted of 128 patients, with long-term results available for 87 individuals, including 24 patients with SPT1, 20 with SPT2, 27 with SPT3, and 16 with SPT4. The average age was 70 years, with a slight male majority (56.3%) and a mean BMI of 27.9 kg/m2. After a median follow-up of 48 months, all groups showed significant improvement in walking distance, leg pain, and disability. Overall, 75% reported satisfaction with the surgery. However, patients with SPT1, which is characterized by low sacral slope and specific spinal curvatures, experienced significantly less improvement in back pain (p = 0.018) and related disability (p = 0.030), and lower satisfaction compared to other SPT groups (p = 0.008). CONCLUSIONS The sagittal spinal type is influencing the long-term outcome of patients suffering from symptomatic LSS. Patients with a combination of a flat sacral slope and a low overall lumbar lordosis with a high lordosis in the lower lumbar spine (i.e., spinal SPT1) showed worse outcome concerning back pain and had decreased satisfaction with surgery than comparable subjects from other SPT groups. Consequently, the authors recommend the assessment of sagittal spinal types in patients diagnosed with symptomatic spinal stenosis prior to decompression surgery. Inclusion of SPT in the preoperative consultation process can provide valuable insights, potentially guiding practitioners to more tailored patient counseling.

Nusinersen in adults with type 3 spinal muscular atrophy: long-term outcomes on motor and respiratory function.

Nusinersen was approved for 5q spinal muscular atrophy (SMA), irrespective of age, SMA type or functional status. Nonetheless, long-term data on adults with milder phenotypes are scarce. We aimed to characterize evolution on motor and respiratory function in our cohort of adults with type 3 SMA. We conducted a longitudinal retrospective single-center study, including adults (≥18years) with type 3 SMA under nusinersen for > 22months. We reported on motor scores and spirometry parameters. Ten patients were included, with a median follow-up of 34months (range = 22-46). Four patients (40%) were walkers. None used non-invasive ventilation. In Revised Upper Limb Module (RULM) and Expanded Hammersmith Functional Motor Scale (HFMSE), difference of medians increased at 6, 22 and 46months comparing to baseline (-0.5 vs. + 1.5 vs. + 2.5 in RULM; + 4.0 vs. + 7.5 vs. + 6.0 in HFMSE). Two (50%) walkers presented a clinically meaningful improvement in 6-min walk distance. We did not report any clinically meaningful decrement in motor scores. Spirometry parameters showed an increasing difference of medians in maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) (-3 vs. + 13.4 vs. + 28.7 percentage points of predicted value for MIP; + 11.8 vs. + 13.1 vs. 13.3 percentage points of predicted value for MEP). Our cohort supports a sustained benefit of nusinersen in adults with type 3 SMA, in motor and respiratory function. Multicentric studies are still warranted.

Liraglutide for Lower Limb Perfusion in People With Type 2 Diabetes and Peripheral Artery Disease

Peripheral artery disease (PAD) in diabetes may lead to diabetic foot ulcer and lower-extremities amputation. Glucagon-like peptide 1 receptor agonists have proven cardiovascular benefits in trials of people with type 2 diabetes at high cardiovascular risk. To examine the effect of liraglutide on peripheral perfusion measured as peripheral transcutaneous oxygen pressure (TcPo2) in individuals with type 2 diabetes and PAD. This open-label randomized clinical trial was conducted between February 1, 2021, and June 30, 2022, with a final follow-up on December 30, 2022, at University of Campania "Luigi Vanvitelli," Naples, Italy. Fifty-five individuals with type 2 diabetes, PAD, and TcPo2 between 30 and 49 mm Hg were included. Patients were randomized to receive 1.8 mg of subcutaneous liraglutide or conventional treatment of cardiovascular risk factors (control group) for 6 months. Coprimary outcomes were the change from baseline of peripheral perfusion between groups and the comparison of the proportion of individuals who reached 10% increase of TcPo2 from baseline in each group. Fifty-five participants (mean [SD] age, 67.5 [8.5] years; 43 [78%] male) were randomized (27 to the liraglutide group and 28 to the control group) and analyzed. Participants had a median (IQR) hemoglobin A1c level of 6.9% (6.5%-7.8%) and a mean (SD) TcPo2 of 40.3 (5.7) mm Hg. Transcutaneous Po2 increased over time in both groups, with significant differences favoring the liraglutide group after 6 months (estimated treatment difference, 11.2 mm Hg; 95% CI, 8.0-14.5 mm Hg; P < .001). The 10% increase of TcPo2 occurred in 24 participants (89%) in the liraglutide group and 13 (46%) in the control group (relative risk, 1.91; 95% CI, 1.26-2.90; P < .001). Compared with the control group, individuals in the liraglutide group had a significant reduction of C-reactive protein (-0.4 mg/dL; 95% CI, -0.7 to -0.07 mg/dL; P = .02), urinary albumin to creatinine ratio (-119.4 mg/g; 95% CI, -195.0 to -43.8 mg/g; P = .003), and improvement of 6-minute walking distance (25.1 m; 95% CI, 21.8-28.3 m; P < .001). In this randomized clinical trial of people with type 2 diabetes and PAD, liraglutide increased peripheral perfusion detected by TcPo2 measurement during 6 months of treatment. These results support the use of liraglutide to prevent the clinical progression of PAD in individuals with type 2 diabetes. ClinicalTrials.gov Identifier: NCT04881110.

Effects of calcitonin on lumbar spinal stenosis.

Systematic review and meta-analysis. There is some controversy about the effects of calcitonin (CT) on lumbar spinal stenosis (LSS). This systematic review and meta-analysis is to assess the strength of the evidence supporting the use of CT in the treatment of patients with LSS. We performed an electronic search depicting randomized controlled trials (RCTs) through 4 databases from the date of database creation to January 2023. 3 different researchers conducted independent literature screening, data extractions, and quality assessments. The outcome measures included visual analogue scale (VAS), walking distance, and oswestry disability index (ODI). Meta-analysis and trial sequence analysis (TSA) were carried out using RevMan 5.4, Stata 16.0, and TSA 0.9. GRADE 3.6 was used to evaluate the evidence quality. We accepted 9 studies with 496 participants. The meta-analysis revealed that CT offered no significant improvement in VAS, walking distance, or ODI in patients with LSS. There is no evidence that CT has a benefit in patients with LSS, either alone or in combination with other treatments, or depending on the route of administration, according to the systematic review and meta-analysis of relevant RCTs.

Cilostazol for peripheral arterial disease - a position paper from the Italian Society for Angiology and Vascular Medicine.

Cilostazol is a quinolinone-derivative selective phosphodiesterase inhibitor and is a platelet-aggregation inhibitor and arterial vasodilator for the symptomatic treatment of intermittent claudication (IC). Cilostazol has been shown to improve walking distance for patients with moderate to severe disabling intermittent claudication who do not respond to exercise therapy and who are not candidates for vascular surgical or endovascular procedures. Several studies evaluated the pharmacological effects of cilostazol for restenosis prevention and indicated a possible effect on re-endothelialization mediated by hepatocyte growth factor and endothelial precursor cells, as well as inhibiting smooth muscle cell proliferation and leukocyte adhesion to endothelium, thereby exerting an anti-inflammatory effect. These effects may suggest a potential effectiveness of cilostazol in preventing restenosis and promoting the long-term outcome of revascularization interventions. This review aimed to point out the role of cilostazol in treating patients with peripheral arterial disease, particularly with IC, and to explore its possible role in restenosis after lower limb revascularization.

PROPOSE. Development and validation of a prediction model for shared decision making for patients with lumbar spinal stenosis

BackgroundDecompression for lumbar spinal stenosis (LSS) is the most frequently performed spine surgery in Denmark. According to the Danish spine registry DaneSpine, at 1 year after surgery, about 75% of patients experiences considerable pain relief and around 66% improvement in quality of life. However, 25% do not improve very much. We have developed a predictive decision support tool, PROPOSE. It is intended to be used in the clinical conversation between healthcare providers and LSS patients as a shared decision-making aid presenting pros and cons of surgical intervention. This study presents the development and evaluation of PROPOSE in a clinical setting. MethodsFor model development, 6.357 LSS patients enrolled in DaneSpine were identified. For model validation, predictor response and predicted outcome was collected via PROPOSE from 228 patients. Observed outcome at 1 year was retrieved from DaneSpine. All participants were treated at 3 Danish spine centers. The outcome measures presented are improvement in walking distance, the Oswestry Disability Index, EQ-5D-3L and leg/back pain on the Visual Analog Scale. Outcome variables were dichotomized into success (1) and failure (0). With the exception of walking distance, a success was defined as reaching minimal clinically important difference at 1-year follow-up. Models were trained using Multivariate Adaptive Regression Splines. Performance was assessed by inspecting confusion matrix, ROC curves and comparing GCV (generalized cross-validation) errors. Final performance of the models was evaluated on independent test data. ResultsThe walking distance model demonstrated excellent performance with an AUC of 0.88 and a Brier score of 0.14. The VAS leg pain model had the lowest discriminatory performance with an AUC of 0.67 and a Brier score of 0.22. ConclusionsPROPOSE works in a real-world clinical setting as a proof of concept and demonstrates acceptable performance. It may have the potential of aiding shared decision making.

Improvement of Pain-Free Walking Distance with Implementation of Treadmill Protocol

Peripheral arterial disease (PAD) may cause lower extremity pain that can impair activities of daily living. At a vascular clinic in rural New Mexico, peripheral arterial disease patients are managed but their symptoms continue to worsen so an evidence- based solution was sought. The purpose of this quantitative, quasi-experimental project was to determine if or to what degree the translation of McDermott et al.’s published research on the Gardner-Skinner Protocol will impact the pain-free walking distance when compared to current practice among peripheral arterial disease patients with intermittent claudication in a university activity center in rural New Mexico over four weeks. Dorothea Orem's self-care theory and Kurt Lewin's change theory provided the project's theoretical foundations. Data on walking distance was measured using the Six-Minute Walk Test in PAD patients (n = 12) and were compared at baseline and four weeks post-implementation of the intervention. A paired t-test showed no statistically significant difference in pain-free walking distance from baseline (M = 267.85, SD = 244.05) to post-intervention (M= 339.58, SD= 191.42), t (11) = -1.27, p= .23. Despite the lack of statistical significance, there was clinical significance in that the mean increase in pain-free walking distance increased by 70.83 feet. Therefore, the implementation of the Gardner-Skinner Protocol may improve walking distance in this population of patients. Recommendations are to continue the implementation and continue to analyze data for six months prior to dissemination.

Physiotherapy versus alternative medicine for pain and quality of life in patients with lumbar spinal stenosis: a systematic review with meta-analysis

IntroductionLumbar spinal stenosis (LSS) is a prevailing condition widely affecting mobility. However, many non-invasive treatments have been proposed for LSS. Physiotherapy is reported as more commonly used with very little evidence reporting the efficacy of alternative medicine. For clinicians, there was a need to find a better mode of treatment. The purpose of this paper is to compare the effectiveness of physiotherapy interventions and alternative medicine for leg pain, back pain, and walking distance in patients with LSS.MethodsData sources: PubMed, Web of Science, and Scopus databases were searched for papers published in the previous 5 years (2016–2020). The systematic review and meta-analysis were conducted from September 2021 to December 2021 at the Musculoskeletal Research Lab of Maharishi Markandeshwaer Institute of Physiotherapy &amp; Rehabilitation. Study selection and outcomes: randomised controlled trials (RCT), randomised clinical trials, randomised cross-over trials, quasi-RCTs, and non-RCTs were included if they evaluated the effects of physiotherapy or alternative medicine on pain and walking distance in patients with LSS. The Numeric Rating Scale (NRS), Visual Analogue Scale (VAS), Self-paced walk test (SPWT), and treadmill walking were used as outcome measures. All the authors independently screened and extracted data from the 8 studies retrieved through the search using a pilot-tested performa. The quality of studies was assessed using the PEDro scale and the Cochrane risk of bias criteria.ResultsMeta-analysis was performed using a fixed-effects model that showed (1) Physiotherapy was more effective than the control in improving leg pain. The Standardised mean difference (SMD) (95% CI) in the NRS score for leg pain was found to be 1.12 (0.83, 1.40); (2) Physiotherapy was more effective than the control in improving back pain. The SMD (95% CI) in the NRS score for back pain was 0.29 (−0.18, 0.76); (3) Physiotherapy was more effective than the control in improving walking distance. The SMD (95% CI) for walking distance was found to be 144.59 m (133.16 m, 159.02 m).ConclusionsThe results of the present study indicate that physiotherapy has higher significant results than alternative medicine in patients with lumbar spinal stenosis.
