nd 6 associated with an anterior coloplasty with a mesh. The only patient of group 2 with a recurrence was submitted to a Hartmann's operation. Preoperative vs postoperative mean (SD) continence score was 15.8 (3.1) and 15.6 (3.3) versus 4.1 (1.8) and 3.9 (1.9) in group 1 and 2, respectively (P less then 0.001). All parameters of SF-36 improved after surgery (P less then 0.01) and no differences between the 2 groups were found CONCLUSIONS Long-term results confirmed the safety and effectiveness of Altemeier's procedure for the treatment of complete rectal prolapse, with the limit of a non-negligible incidence of anastomotic complications and recurrences. The combination of Altemeier with TOCS showed a positive trend to a reduction of the recurrence rate, not worsening morbidity and outcomes.Membrane capacitance and transmembrane potential are sensitive to the proximity of neighboring biological cells which eventually induces anisotropic perturbation of the local electric field distribution in a cell assembly and/or a tissue. The development of robust and reliable multiphysics approaches is essential to solve the challenge of analyzing proximity-induced capacitance coupling (CC) between cells. In this study, we ask to what extent this CC is a minor perturbation on the individual cells or whether it can fundamentally affect bio-electromechanical cues. A key component of our continuum electromechanical analysis is the consideration of elastic models of cells under steady state electric field excitation to characterize electrodeformation (ED). Analyzing the difference between the ED force for a pair of cells and its counterpart for a single reference cell allows us to determine a separation distance-orientation angle diagram providing evidence of a separation distance beyond which the electrostatic interactions between a pair of biological cells become inconsequential for the ED. An attenuation-amplification transition of ED force in this diagram suggests that anisotropy induced by the orientation angle of the cell pair relative to the applied electric field direction has a significant influence on ED and CC. We furthermore observe that the shape of this diagram changes when extracellular conductivity is varied. The results obtained are then contrasted with the corresponding diagrams of similar cell configurations under an oscillating electric field excitation below and above the α-dispersion frequency. This investigation may provide new opportunities for further assessment of electromechanical properties of engineered tissues.Circular dichroism (CD) spectroscopy is a well-established biophysical technique used to investigate the structure of molecules. The analysis of a protein CD spectrum depends on the quality of the original CD data, which can be affected by the sample purity, background absorption of the additives/solvent/buffer, the choice of the parameters used for data collection, etc. In this paper, the CD spectrum of myoglobin was used as a model to exploit how variations on each data collection parameter could affect the final protein CD spectrum and, the subsequent effect of them on the quantitative analysis of protein secondary structure. Bioinformatics analysis carried out with SESCA package and PDBMD2CD server predicted a theoretical myoglobin CD spectrum, and a Monte Carlo-like model was implemented to estimate the uncertainty in secondary structure predictions performed with CDSSTR, Selcon 3 and ContinLL algorithms. An inappropriate choice of data collection parameters can lead to a misinterpretation of the CD data in terms of the protein structural content.
Postoperative adhesive bowel obstruction (ABO) is a common complication especially in complicated appendicitis. This study aimed to analyze the risk factors for ABO following appendectomy in children with complicated appendicitis, and establish a scoring model for predicting postoperative ABO and treatment option to relieve the obstruction.
From December 2014 to January 2020, all files of consecutive patients with complicated appendicitis underwent appendectomy were reviewed. Univariate and multivariate analyses were used to screen out the risk factors of postoperative ABO, and establish a scoring model for predicting postoperative ABO and surgical relief to relieve the obstruction.
Of the 780 patients, 87 (11.2%) had ABO following appendectomy, including 27 who underwent surgical relief. Age ≤ 6years, overweight and obesity, duration of symptoms ≥ 36h, C-reactive protein ≥ 99mg/L, duration of operation ≥ 60min, intraoperative peritoneal lavage, and postoperative flatus time ≥ 20h were independent risk
Cerebrospinal fluid (CSF) leakage is a common complication after neurosurgical intervention. It is associated with substantial morbidity and increasedhealthcare costs. The current systematic review and meta-analysis aim to quantify the incidence of cerebrospinal fluid leakage in the pediatric populationand identify its risk factors.
The authors followed the PRISMA guidelines. The Embase, PubMed, and Cochrane database were searched for studies reporting CSF leakage afterintradural cranial surgery in patients up to 18 years old. ML792 Meta-analysis of incidences was performed using a generalized linear mixed model.
Twenty-six articles were included in this systematic review. Data were retrieved of 2929 patients who underwent a total of 3034 intradural cranial surgeries.Surprisingly, only four of the included articles reported their definition of CSF leakage. The overall CSF leakage rate was 4.4% (95% CI 2.6 to 7.3%). Theodds of CSF leakage were significantly greater for craniectomy as opposed to craniotomy (OR 4.7, 95% CI 1.7 to 13.4) and infratentorial as opposed tosupratentorial surgery (OR 5.9, 95% CI 1.7 to 20.6). The odds of CSF leakage were significantly lower for duraplasty use versus no duraplasty (OR 0.4195% CI 0.2 to 0.9).
The overall CSF leakage rate after intradural cranial surgery in the pediatric population is 4.4%. Risk factors are craniectomy and infratentorial surgery.Duraplasty use is negatively associated with CSF leak. We suggest defining a CSF leak as "leakage of CSF through the skin," as an unambiguous definitionis fundamental for future research.
