Puberty and risky decision-making in male adolescents

Pubertal development is a potential trigger for increases in risk-taking behaviours during adolescence. Here, we sought to investigate the relationship between puberty and neural activation during risky decision-making in males using functional magnetic resonance imaging (fMRI). Forty-seven males aged 12.5–14.5 years completed an fMRI risk-taking task (BART) and reported their tendencies for risky decision-making using a self-report questionnaire. Puberty was assessed through self-reported pubertal status and salivary testosterone levels. Testosterone concentration, but not physical pubertal status, was positively correlated with self-reported risk-taking behaviour, while neither was correlated with BART performance. Across the whole sample, participants had greater activation of the bilateral nucleus accumbens and right caudate on trials when they made a successful risky decision compared to trials when they made a safe choice or when their risky decision was unsuccessful. There was a negative correlation between pubertal stage and brain activation during unsuccessful risky decision-making trials compared within unsuccessful control trials. Males at a lower stage of pubertal development showed increased activation in the left insula, right cingulate cortex, dorsomedial prefrontal cortex (dmPFC), right putamen and right orbitofrontal cortex (OFC) relative to more pubertally mature males during trials when they chose to take a risk and the balloon popped compared to when they watched the computer make an unsuccessful risky decision. Less pubertally mature males also showed greater activation in brain regions including the dmPFC, right temporal and frontal cortices, right OFC, right hippocampus and occipital cortex in unsuccessful risky trials compared to successful risky trials. These results suggest a puberty-related shift in neural activation within key brain regions when processing outcomes of risky decisions, which may reduce their sensitivity to negative feedback, and in turn contribute to increases in adolescent risk-taking behaviours.     

Economic impact of work disability due to chronic low back pain from the patient perspective

ObjectivesLow back pain (LBP) is one of the main expenditure items for health systems. Data on the economic impact of LBP are uncommon from the patient perspective. The aim of this study was to estimate the economic impact of work disability related to chronic LBP from the patient perspective.MethodsWe conducted a cross-sectional analysis from patients aged over 17 years suffering from non-specific LBP for at least 3 months. Systematic medical, social and economic assessments were collected: pain duration and intensity; functional disability with the Quebec Back Pain Disability Scale (0–100); quality of life with the Dallas Pain Questionnaire; job category; employment status; duration of work disability due to LBP, and income. Factors associated with loss of income were identified by multivariable logistic regression analysis.ResultsWe included 244 workers (mean age 43 ± 9 years; 36% women); 199 patients had work disability, including 196 who were on sick leave, 106 due to job injury. Three were unemployed due to layoff for incapacity. The mean loss of income for patients with work disability was 14% [SD 24, range −100 to 70] and was significantly less for patients on sick leave due to job injury than on sick leave not related to job injury (p < 0.0001). On multivariable analysis, the probability of loss of income with LBP was about 50% less for overseers and senior managers than workers or employees (odds ratio 0.48 [95% confidence interval 0.23–0.99]).ConclusionWork disability due to LBP resulted in loss of income in our study. The loss of income depended on the type of social protection and job category. It was reduced for patients on sick leave related to work injury and for overseers and senior managers.     

Intra-articular Injection of Bone Marrow Concentrate for Treatment of Patellofemoral Osteoarthritis: Preliminary Results Utilizing an Ultrasound-Guided Marrow Harvesting Technique

ObjectiveTo assess the effectiveness of intra-articular injection of bone marrow concentrate (BMC) under ultrasound (US) guidance in the treatment of patellofemoral osteoarthritis (OA), with clinical and volumetric magnetic resonance (MR) imaging follow-up.MethodsThis retrospective study included 96 consecutive patients referred for US-guided intra-articular injection of BMC for symptomatic patellofemoral OA for which conservative treatment had failed. A control group of 21 patients with symptomatic patellofemoral OA was included for comparison. Data on International Knee Documentation Committee (IKDC), Visual Analog Scale (VAS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores as well as volumetric MR imaging (using T2 mapping sequence) were collected before and 12 months after injection, and the results were compared.ResultsNo technical adverse events were noted during bone marrow aspiration, BMC preparation, or intra-articular injection of BMC. No clinical adverse events were reported during long-term follow-up. All mean scores improved between baseline and 12 months after intra-articular injection of BMC (VAS 5.5 to 3.6, P < .0001; WOMAC 36.8 to 22.2, P < .0001; and IKDC 41.8 to 58.2, P < .0001). MR imaging at 1 year of follow-up after BMC treatment showed no statistically significant difference in hyaline cartilage volume compared with that at the baseline (P = .690), suggesting stabilization of the cartilage degradation process. In contrast, the group of untreated patients showed a significant decrease in the cartilage volume (P = .001), corresponding to a cartilage loss of 6.9%.ConclusionsThe results suggest that intra-articular injection of BMC under US guidance could be a promising option for the treatment of symptomatic patellofemoral OA and could promote the preservation of healthy residual cartilage volume.     

Arthroscopic knee debridement in osteoarthritis in the older age can be satisfactory

IntroductionKnee arthroscopy is one of the treatments for knee pain. In recent years, the use of knee arthroscopy in the treatment of osteoarthritis was challenged by several randomized-controlled trials, systematic reviews and meta-analyses. However, some design flaws are making the clinical decision harder. This study specifically explores the patient satisfaction from these surgeries to aid in clinical decision.HypothesisKnee arthroscopy can relieve symptoms and delay further surgical treatment in the older age.Patients & methodsFifty patients accepted participation and were invited to a follow-up examination eight years post knee arthroscopy. All patients were above age 45 and diagnosed with degenerative meniscus tear and osteoarthritis. The patients filled follow-up questionnaires of function (WOMAC, IKDC, SF-12) and pain. The patients were asked to appreciate if they would have repeated the surgery retrospectively. The results were compared to a previous data base.ResultsThirty-six patients (72%) reported satisfaction of 8 and above (scale of 0–10) from the surgery and would have repeated it. A higher SF-12 physical score pre-surgery predicted a higher satisfaction rate (p = 0.027). Patients who were more satisfied from the surgery improved post-surgery in all parameters compared with the less-satisfied group (p < 0.001). Patients above the age 60 had similar parameters pre- and post-surgery compared with patients under the age 60 (p > 0.05).ConclusionsPatients between the ages 46–78 with degenerative meniscus tear and osteoarthritis felt they benefited from knee arthroscopy in an eight-year follow-up and would repeat the surgery. Our research may help with better patient selection and suggest knee arthroscopy can relive symptoms and delayed further surgical treatment for the older patient with clinical symptoms and signs of meniscus related pain, mild osteoarthritis, and failed conservative treatment.Level of evidenceIV.     

An Interim Analysis of the First 102 Patients Treated in the Prospective Vertebral Augmentation Sacroplasty Fracture Registry

PurposeTo evaluate the efficacy of sacroplasty for treating sacral insufficiency fractures, including the effect on pain relief, patient function and adverse event rates in an as-treated on-label prospective data registry.Materials and MethodsObservational data including patient reported outcomes (PROs), patient characteristics, osteoporosis treatment, fracture duration, cause of sacral fractures and image guidance used for treatment were collected for patients undergoing sacroplasty. The PROs were collected at baseline then at one, three, and at six months following the procedure. The primary outcomes were pain as measured by the Numerical Rating Scale (NRS) and function as measured by the Roland Morris Disability Questionnaire (RMDQ). Secondary outcomes included adverse events, cement leakage, new neurologic events, readmissions and death.ResultsThe interim results for the first 102 patients included significant pain reduction with mean pain improvement scores at six months decreasing from 7.8 to 0.9 (P < .001) and significant improvement in function with mean RMDQ scores improving from 17.7 to 5.2 (P < .001). Most procedures were performed under fluoroscopy (58%). There was cement leakage in 17.7% of the subjects but only one adverse event which was a new neurologic deficit related to cement extravasation. The readmission rate was 16% mostly due to additional back pain and fractures and there were no subject deaths.ConclusionsSacroplasty with cement augmentation for acute, subacute and chronic painful sacral insufficiency fractures caused by osteoporosis or neoplastic disorders results in highly significant improvements in pain and function with very low rate of procedural related adverse events.
