This new classification summarizes all the pathological scenarios of the sagittal alignment of AIS into four patterns. A specific surgical planning can be extrapolated for each pattern. In type 1, the objective is to preserve the sagittal shape. In type 2, the objective is to restore thoracic kyphosis. In type 2b, TL junction should be straightened. In type 3, the objective is to reshape the lower arc of thoracic sagittal angle and straighten the TL junction. These slides can be retrieved under Electronic Supplementary Material.
The hypothalamus contains integrative systems that support life, including physiological processes such as food intake, energy expenditure, and reproduction. Here, we show that anorexia nervosa (AN) patients, contrary to normal weight and constitutionally lean individuals, respond with a paradoxical reduction in hypothalamic levels of glutamate/ glutamine (Glx) upon feeding. This reversal of the Glx response is associated with decreased wiring in the arcuate nucleus and increased connectivity in the lateral hypothalamic area, which are involved in the regulation on a variety of physiological and behavioral functions including the con-trol of food intake and energy balance. The identification of distinct hypothalamic neurochemical dysfunctions and associated structural variations in AN paves the way for the development of new diagnostic and treatment strategies in conditions associated with abnormal body mass index and a maladaptive response to negative energy balance.
The three phenotypes highlighted by this study could be useful to identify children with high risk of cross-allergic reaction to TNs and legumes early after PA diagnosis.
Aim
To describe coping strategies in children and adolescents with cerebral palsy (CP), relative to age.
Method
Patients were prospectively recruited from two paediatric rehabilitation centres in France. The Pediatric Pain Coping Inventory – French and Structured Pain Questionnaire were completed by an experienced professional for each child.
Results
One hundred and forty‐two children with CP were included (80 males, 62 females; median age 12y; IQR=8–15y). They generally used fewer coping strategies than typically developing children (‘Seeks social support and action’: 12.47 vs 12.85, p=0.477; ‘Cognitive self‐instruction’: 9.28 vs 10.90, p<0.001; ‘Distraction’: 4.89 vs 7.00, p<0.001; ‘Problem solving’: 4.43 vs 5.19, p<0.001). In the CP group, ‘Seeks social support and action’ decreased with age (p=0.021) and ‘Cognitive self‐instruction’ increased with age (p<0.001). ‘Problem solving’ and ‘Distraction’ did not change with age. Coping strategies were influenced by Gross Motor Function Classification System level (p=0.022) and history of surgery (p=0.002).
Interpretation
Children with CP generally used fewer coping strategies than typically developing children and tended to rely on social support. Use of active strategies increased with age; however, they appeared later than in typically developing children and were used to a lesser extent.
What this paper adds
Children with cerebral palsy (CP) use fewer pain‐coping strategies than typically developing children.
Children with CP tend to use social support to cope with pain.
Children with CP learn more appropriate strategies from previous painful experiences.
Active coping strategies appear later but remain underused in children with CP.
Objective
To compare the effectiveness and safety of laparoscopic sacropexy (LS) and transvaginal mesh (TVM) at 4 years.
Design
Extended follow up of a randomised trial.
Setting
Eleven centres.
Population
Women with cystocele stage ≥2 (pelvic organ prolapse quantification [POP‐Q], aged 45–75 years without previous prolapse surgery.
Methods
Synthetic non‐absorbable mesh placed in the vesicovaginal space and sutured to the promontory (LS) or maintained by arms through pelvic ligaments and/or muscles (TVM).
Main outcome measures
Functional outcomes (pelvic floor distress inventory [PFDI‐20] as primary outcome); anatomical assessment (POP‐Q), composite outcome of success; re‐interventions for complications.
Results
A total of 220 out of 262 randomised patients have been followed at 4 years. PFDI‐20 significantly improved in both groups and was better (but below the minimal clinically important difference) after LS (mean difference −7.2 points; 95% CI −14.0 to −0.05; P = 0.029). The improvement in quality of life and the success rate (LS 70%, 61–81% versus TVM 71%, 62–81%; hazard ratio 0.92, 95% CI 0.55–1.54; P = 0.75) were similar. POP‐Q measurements did not differ, except for point C (LS −57 mm versus TVM −48 mm, P = 0.0093). The grade III or higher complication rate was lower after LS (2%, 0–4.7%) than after TVM (8.7%, 3.4–13.7%; hazard ratio 4.6, 95% CI 1.007–21.0, P = 0.049)).
Conclusions
Both techniques provided improvement and similar success rates. LS had a better benefit–harm balance with fewer re‐interventions due to complications. TVM remains an option when LS is not feasible.
Tweetable abstract
At 4 years, Laparoscopic Sacropexy (LS) had a better benefit–harm balance with fewer re‐interventions due to complications than Trans‐Vaginal Mesh (TVM).
OBJECTIVEThe best predictors of height gain due to surgical correction are the number of fused vertebrae and the degrees of the corrected Cobb angle. Existing studies of predictive models measured the radiographic spinal height and did not report the clinical height gain. The aims of this study were to determine the best predictive factors of clinical height gain before surgical correction, construct a predictive model using patient population data for machine learning, and test the performance of this model on a validation population.METHODSThe authors reviewed 145 medical records of consecutive patients who underwent surgery that included placement of posterior spinal instrumentation and fusion for idiopathic scoliosis between 2012 and 2016. Standing and sitting clinical heights were measured before and after surgery in patients who had been surgically treated under similar conditions. Multivariate analysis was then performed and the results were used to develop a predictive model for height gain after surgery. The data from the included patients were randomly assigned to a learning set or a test set.RESULTSIn total, 116 patients were included in the analysis, for whom the average postoperative clinical height gain in a standing position was 4.2 ± 1.8 cm (range 0–11 cm). The best prediction model was calculated as follows: standing clinical height gain (cm) = 1 − 0.023 × sitting clinical height (cm) − 0.19 × Risser stage + 0.058 × Cobb preoperative angle (°) + 0.021 × T5–12 kyphosis (°) + 0.14 × number of levels fused. In the validation cohort, 91% of the predicted values had an error of less than one-half of the actual height gain.CONCLUSIONSThis predictive model formula for calculating the potential postoperative height gain after surgical treatment can be used preoperatively to inform idiopathic scoliosis patients of what outcomes they may expect from posterior spinal instrumentation and fusion (taking into account the model’s uncertainty).
