Can People with Chronic Neck Pain Recognize Their Own Digital Pain Drawing?
Background: Although the reliability of pain drawings (PDs) has been confirmed in people with chronic pain, there is a lack of evidence about the validity of the PD, that is, does the PD accurately represent the pain experience of the patient?
Objectives: We investigate whether people with chronic neck pain (CNP) can recognize their own PD to support the validity of the PD in reporting the experience of pain. Moreover, we
examined the association between their ability to recognize their own PD with their levels of pain intensity and disability and extent of psychosocial and somatic features.
Study Design: Experimental.
Setting: University Laboratory.
Methods: Individuals with CNP completed their PD on a digital body chart, which was then automatically modified with specific dimensions using a novel software, providing an objective range of distortion and eliminating errors, which could potentially occur in manually controlled visual-subjective based methods. Following a 10-minute break listening to music, a series of 20 PDs were presented to each patient in a random order, with only 2 being their original PD. For each PD, the patients rated its likeliness to their own original PD on a scale from 0 to 100, with 100 representing âthis is my pain.â
Results: Overall, the patients rated their original PD with a median score of 92% similarity, followed by 91.8% and 89.5% similarity when presented with a PD scaled down to 75%
and scaled up by 150% of the original size, respectively; these scores were not significantly different to the ratings given for their original PD. The PD with horizontal translation by 40 pixels (8%) and vertical translation by 70 pixels (12.8%) were rated as the most dissimilar to their original PD; these scores were significantly different to their original PD scores. The Spearman correlation coefficient revealed a significant negative association between their ability to recognize their original PD and their Modified Somatic Perceptions Questionnaire scores.
Limitations: The patients in the study presented with relatively mild CNP, and the results may not be generalized to those with more severe symptoms.
Conclusions: People with CNP are generally able to identify their own PD but that their ability to recognize their original PD is negatively correlated with the extent of somatic awareness
Effects of 12 Weeks of Essential Amino Acids (EAA)-Based Multi-Ingredient Nutritional Supplementation on Muscle Mass, Muscle Strength, Muscle Power and Fatigue in Healthy Elderly Subjects: A Randomized Controlled Double-Blind Study
Objective: To counteract muscle mass, muscle strength and power loss during aging, and to study age-related change of neuromuscular manifestation of fatigue in relation to nutritional supplementation. Design: randomized controlled double-blind study. Setting: Twice-daily consumption for 12 weeks of an Essential Amino Acids (EAA)-based multi-ingredient nutritional supplement containing EAA, creatine, vitamin D and Muscle Restore ComplexŸ. Participants: 38 healthy elderly subjects (8 male, 30 female; age: 68.91±4.60 years; body weight: 69.40±15.58 kg; height: 1.60±0.09 m) were randomized and allocated in supplement (SUPP) or placebo (PLA) group. Mean Measurements: Vitamin D blood level; Appendicular Lean Mass (ALM); Visceral Adipose Tissue (VAT); Maximal Voluntary Contraction (MVC) and Peak Power (PP); myoelectric descriptors of fatigue: Fractal Dimension and Conduction Velocity initial values (FD iv, CV iv), their rates of change (FD slopes, CV slopes) and the Time to perform the Task (TtT). Mean Results: Significant changes were found in SUPP compared to baseline: Vitamin D (+8.73 ng/ml; p<0.001); ALM (+0.34 kg; p<0.001); VAT (-76.25 g; p<0.001); MVC (+0.52 kg; p<0.001); PP (+4.82 W; p<0.001). Between group analysis (SUPP Vs. PLA) showed improvements: vitamin D blood levels (+11,72 ng/ml; p<0.001); Legs FFM (+443.7 g; p<0.05); ALM (+0.53 kg; p<0.05); MVC (+1.38 kg; p<0.05); PP (+9.87 W; p<0.05). No statistical changes were found for FD iv, CV iv, FD and CV slopes and TtT, either compared to baseline or between groups. Significant correlations between mean differences in SUPP group were also found. Conclusion: The study demonstrates that in healthy elderly subjects an EAA-based multi-ingredient nutritional supplementation of 12 weeks is not effective to change myoelectric manifestation of fatigue and TtT failure but can positively affect muscle mass, muscle strength, muscle power and VAT, counterbalancing more than one year of age-related loss of muscle mass and strength
Families_Share: digital and social innovation for workâlife balance
Purpose: The European H2020 Families_Share project aims at offering a grass-root approach and a co-designed platform supporting families for sharing time and tasks related to childcare, parenting, after-school and leisure activities and other household tasks. To achieve this objective, the Families_Share project has been built on current practices which are already leveraging on mutual help and support among families, such as Time Banks, Social Streets and self-organizing networks of parents active at the neighbourhood level and seek to harness the potential of ICT networks and mobile technologies to increase the effectiveness of participatory innovation. The aim of this paper is to present and discuss the Families_Share methodology and platform, as well as the results obtained by several partecipating communities in different European countries. Design/methodology/approach: This paper discusses how the Families Share approach (CAPS project, Horizon 2020) is bringing the sharing economy to childcare. Families Share developed a co-caring approach and a co-designed digital welfare platform to support parents with sharing time and tasks related to childcare, after-school and leisure activities. Families Share conducted two iterative pilot experiments and related socio-economic evaluations in six European cities. More than 3,000 citizens were engaged in the co-design process through their local community organizations and more than 1,700 parents and children actively experimented with the approach by organizing collaborative childcare activities. The authors discuss the challenges and solutions of co-designing a socio-technical approach aimed at facilitating socially innovative childcare models, and how the Families Share approach, based on technology-supported co-production of childcare, may provide a new sustainable welfare model for municipalities and companies with respect to lifeââwork balance. Findings: The authors discuss the challenges and solutions of co-designing a technological tool aimed at facilitating socially innovative childcare models, and how the Families Share approach may provide a new sustainable welfare model for municipalities and companies with respect to workâlife balance. Originality/value: As a main difference with state-of-the-art proposals, Families_Share is aimed to provide support to networks of parents in the organization of self-managed activities, this way being orthogonal with respect either to social-network functionalities or to supply and demand services. Furthermore, Families_Share has been based on a participative approach for both the ICT platform and the overall structure
The impact of time interval between hepatic resection and liver transplantation on clinical outcome in patients with hepatocellular carcinoma
Hepatic resection (HR) for hepatocellular carcinoma (HCC) may require secondary liver transplantation (SLT). However, a previous HR is supposed to worsen post-SLT outcomes. Data of patients treated by SLT between 2000 and 2018 at two tertiary referral centers were analyzed. The primary outcome of the study was to analyze the impact of HR on post-LT complications. A Comprehensive Complication Index â„ 29.6 was chosen as cutoff. The secondary outcome was HCC-re-lated death by means of competing-risk regression analysis. In the study period, 140 patients were included. Patients were transplanted in a median of 23 months after HR (IQR 14â41). Among all the features analyzed regarding the prior HR, only time interval between HR and SLT (time HR-SLT) was an independent predictor of severe complications after LT (OR = 0.98, p < 0.001). According to fractional polynomial regression, the probability of severe complications increased up to 15 months after HR (43%), then slowly decreased over time (OR = 0.88, p < 0.001). There was no significant association between HCC-related death and time HR-SLT at the multivariable competing risks regression model (SHR, 1.06; 95% CI: 0.69â1.62, p = 0.796). This study showed that time HR-SLT was key in predicting complications after LT, without affecting HCC-related death
Sarcopenia Predicts Major Complications after Resection for Primary Hepatocellular Carcinoma in Compensated Cirrhosis
The burden of post-operative complications of patients undergoing liver resection for hepatocellular carcinoma (HCC) is a cause of morbidity and mortality. Recently, sarcopenia has been reported to influence the outcome of patients with cirrhosis. We aimed to assess factors associated with sarcopenia and its prognostic role in liver surgery candidates. We included all patients with compensated advanced chronic liver disease (cACLD) undergoing liver resection for primary HCC consecutively referred to the University of Bologna from 2014 to 2019 with an available preoperative abdominal CT-scan performed within the previous three months. A total of 159 patients were included. The median age was 68 years, and 80.5% of the patients were male. Sarcopenia was present in 82 patients (51.6%). Age and body mass index (BMI) were associated with the presence of sarcopenia at multivariate analysis. Thirteen (8.2%) patients developed major complications and 14 (8.9%) presented PHLF grade B-C. The model for end-stage liver disease score was associated with the development of major complications, whereas cACLD presence, thrombocytopenia, portal hypertension (PH), Child-Pugh score and Albumin-Bilirubin score were found to be predictors of clinically significative PHLF. The rate of major complications was 11.8% in sarcopenic patients with cACLD compared with no complications (0%) in patients without sarcopenia and cACLD (p = 0.032). The rate of major complications was significantly higher in patients with (16.3%) vs. patients without (0%) sarcopenia (p = 0.012) in patients with PH. In conclusion, sarcopenia, which is associated with age and BMI, may improve the risk stratification of post-hepatectomy major complications in patients with cACLD and PH
How does Low Back Pain Influence Muscle Activity during a Cyclical Dynamic Lifting Task?
Title How does LBP Influence Muscle Activity during a Cyclical Dynamic Lifting Task? Authors Andy Sanderson, Corrado Cescon, Nicola R. Heneghan, Alison Rushton, Marco Barbero, Pauline Kuithan, Deborah Falla Purpose Chronic non-specific low back pain (cLBP) is a leading cause of disability, limiting activity in 540 million people globally. High-density electromyography (HDEMG) has been used to investigate changes in back muscle activity in people with cLBP. Previous studies have utilised static or mono-planar tasks or focussed on small areas of the erector spinae (ES). This study uses innovative HDEMG and kinematic analysis to investigate the effect of cLBP on muscle activity and movement during a multi-planar lifting task. Methods Sixteen people with cLBP (8 male, age: 26.9±10.8 years) and sixteen age and gender-matched controls (7 male, age: 31.7±14.0 years) completed the study. HDEMG signals from the ES were detected with four 64-channel semi-disposable 13x5 electrode grids (2 grids bilaterally) covering the lumbar and thoraco-lumbar ES. Kinematic surface markers were placed over the back, enabling 3D motion capture. HDEMG and kinematic data were recorded continuously during a dynamic task involving the cyclical lifting of a 5kg box between 6 shelves for 10 cycles (~7 minutes). The shelves were arranged around the participant, at knee and sternal height, with one pair of shelves anterior and two pairs lateral. To the beat of a metronome, the participant moved the box between shelves, returning to a central shelf each time (10 movements). HDEMG amplitude data were normalised to the first cycle for each movement to a shelf, and factorial ANOVAâs used to compare subsequent cycles to the first. Results Kinematic analysis revealed no significant differences between groups in the movement pattern used to complete the lifting task (P>0.05 for all relevant outcomes). Despite similar movements, significant differences in muscle activity, were seen between groups. The cLBP group showed systematically higher amplitude, indicating higher levels of muscle activity, in 6/10 shelf movements (P0.05). Conclusion As the data were normalised and amplitude is a measure of muscle activity, these results indicate that for a majority of movements, the activity in the ES for the LBP group did not show as great a reduction over the task as that of the control group. These data therefore support an altered motor control strategy in participants with cLBP. While no differences were found in the movement strategy, likely due to the standardisation of the task, cLBP participants showed lower reductions in activity, indicating that already fatigued or dysfunctional muscles remained in use throughout the task
Percutaneous radiofrequency ablation in intrahepatic cholangiocarcinoma: a retrospective single-center experience
Background & aims: Very few data are available in literature about the role of radiofrequency ablation (RFA) in intrahepatic cholangiocarcinoma (ICC) and previous studies are mainly case reports and case series on a very small number of patients and nodules. In this study, we aimed to evaluate effectiveness and safety of RFA for the treatment of unresectable ICC. Methods: This is a retrospective observational cohort study comprising all consecutive patients treated with RFA for unresectable ICC at Policlinico SantâOrsola Malpighi Hospital, Bologna, Italy. Primary endpoint was Local Tumor Progression-Free Survival (LTPFS) while Overall Survival (OS) was also assessed as secondary endpoint. Results: From January 2014 to June 2019, 29 patients with 117 nodules underwent RFA. Technique effectiveness 1 month after RFA was 92.3%; median LTPFS was 9.27 months. Univariate analysis and multivariate analysis showed that LTPFS was significantly related to tumor size â„20 mm. At a median follow up of 39.9 months, median OS from the date of RFA was 27.5 months, with an OS of 89%, 45% and 11% at 1, 2 and 4 years, respectively. Number of overall lesions and the sum of their diameter at the moment of the first RFA significantly affected OS in multivariate analysis. Minor and major complication rates were 14% and 7%, respectively. Conclusion: Tumor size â„20 mm was associated with lower LTPFS, representing a potential useful threshold value. A careful evaluation of tumor burden appears as a crucial element in choosing the best therapeutic strategy in unresectable ICC
Pembrolizumab monotherapy for previously treated metastatic triple-negative breast cancer: cohort A of the phase II KEYNOTE-086 study
ABSTRACT Background Treatment options for previously treated metastatic triple-negative breast cancer (mTNBC) are limited. In cohort A of the phase II KEYNOTE-086 study, we evaluated pembrolizumab as second or later line of treatment for patients with mTNBC. Patients and methods Eligible patients had centrally confirmed mTNBC, â„1 systemic therapy for metastatic disease, prior treatment with anthracycline and taxane in any disease setting, and progression on or after the most recent therapy. Patients received pembrolizumab 200âmg intravenously every 3âweeks for up to 2âyears. Primary end points were objective response rate in the total and PD-L1âpositive populations, and safety. Secondary end points included duration of response, disease control rate (percentage of patients with complete or partial response or stable disease for â„24âweeks), progression-free survival, and overall survival. Results All enrolled patients (N = 170) were women, 61.8% had PD-L1âpositive tumors, and 43.5% had received â„3 previous lines of therapy for metastatic disease. ORR (95% CI) was 5.3% (2.7â9.9) in the total and 5.7% (2.4â12.2) in the PD-L1âpositive populations. Disease control rate (95% CI) was 7.6% (4.4â12.7) and 9.5% (5.1â16.8), respectively. Median duration of response was not reached in the total (range, 1.2+â21.5+) and in the PD-L1âpositive (range, 6.3â21.5+) populations. Median PFS was 2.0âmonths (95% CI, 1.9â2.0), and the 6-month rate was 14.9%. Median OS was 9.0âmonths (95% CI, 7.6â11.2), and the 6-month rate was 69.1%. Treatment-related adverse events occurred in 103 (60.6%) patients, including 22 (12.9%) with grade 3 or 4 AEs. There were no deaths due to AEs. Conclusions Pembrolizumab monotherapy demonstrated durable antitumor activity in a subset of patients with previously treated mTNBC and had a manageable safety profile.
