The aim of this paper is to identify risk factors associated with the development of osteosynthesis plates' related complications in fibula free flap reconstructions. This is a case series study of consecutive fibula free flaps. Clinical and radiological variables were recorded. Patient outcomes were evaluated with special attention to osteosynthesis plates' related complications; these included plate exposure, plate fracture, loosening of screws, non-union, bone resorption, oro-cutaneous fistulas, and bone exposure. We have done a descriptive analysis, univariate analysis, and multivariate logistic regression model to explore possible risk factors for osteosynthesis plates' related complications. Data analysis was performed using R software (version 3.5.0). 111 fibula free flaps were studied. 29 patients (26.1%) developed osteosynthesis plates' related complications. The mean time to osteosynthesis plates' related complications was 22 months; range (1-120); the median and mode were 12 months. Patients with preoperative radiotherapy (34% vs 14%, p = 0.021), and secondary reconstruction (31% vs 15%, p = 0.053) had a higher incidence of osteosynthesis plates' related complications. In the univariate analysis, "preoperative radiotherapy" (OR 3.07, 95%CI = 1.139-8.242, p = 0.025) and "extraoral soft-tissue defect" (OR 2.907, 95%CI = 1.032-8.088, p = 0.042) were risk factors for osteosynthesis plates' related complications. We have observed an interaction effect patients with mandibular Brown's classes III + IV and "secondary reconstruction" have a higher risk for osteosynthesis plates' related complications; more than 47.30 times compared to Brown's class I and "primary reconstruction" (p = 0.026). Different factors may contribute to the development of osteosynthesis plates' related complications. Our study adds important information about these. Patients with higher risk of developing complications should be informed that a second intervention to remove the plates might be necessary.
  NF1 children have cognitive disorders, especially in executive functions, visuospatial, and language domains, the pathophysiological mechanisms of which are still poorly understood.
 
  A correlation study was performed from neuropsychological assessments and brain MRIs of 38 NF1 patients and 42 controls, all right-handed, aged 8-12 years and matched in age and gender. The most discriminating neuropsychological tests were selected to assess their visuospatial, metaphonological and visuospatial working memory abilities. The MRI analyses focused on the presence and location of Unidentified Bright Objects (UBOs) (1), volume analysis (2) and diffusion analysis (fractional anisotropy and mean diffusivity) (3) of the regions of interest including subcortical structures and posterior fossa, as well as shape analysis of subcortical structures (4). The level of attention, intelligence quotient, age and gender of the patients were taken into account in the statistical analysis. Then, we studied how diffusion and volumee NF1 patients have obvious pathological brain characteristics, the neuronal substrates of their cognitive deficits are still not fully understood, perhaps due to complex and multiple pathophysiological mechanisms underlying this disorder, as suggested by the heterogeneity observed in our study.  https://www.selleckchem.com/products/levofloxacin-hydrochloride.html  However, our results are compatible with an interpretation of NF1 as a diffuse white matter disease.In a meticulous study, Humbert, Durr, and colleagues showed evidence for aberrant neurodevelopment in both Huntington's disease (HD) and mouse models of HD. We consider the implications of prenatal pathological changes for the onset and progression of HD and their relatedness to current therapeutic plans.In patients with COPD, distress is significantly prevalent and can have adverse psychological and physiological effects. The Relaxation Response Meditation Technique (RRMT), a technique that elicits the relaxation response, was developed by Dr. Herbert Benson to counter the fight-or-flight response to decrease psychological and physiological effects.
  (1) To assess whether implementing the RRMT decreases anxiety in patients with COPD, (2) to determine whether RRMT reduces the patients' perception of breathlessness, and (3) to investigate whether RRMT improves the physiological responses of patients with COPD.
 
  This quasi-experimental study used a pre- and post-test design. The sample (N=25) consisted of a single group of patients diagnosed in stages 2-4 of COPD at an outpatient pulmonary rehabilitative clinic.
 
  Inferential statistics were used to determine the psychological and physiological differences pre- and post-intervention utilizing the State-Trait Anxiety Inventory, Modified Borg Scale, and BP, HR, respiratory rate, and oxygen saturation levels.
 
  Results indicated a significant mean change in anxiety (p≤0.001), perception of dyspnea (p≤0.001), and a decrease in respiratory rate (p=.001) after implementing the RRMT. There was clinical improvement in systolic and diastolic BPs and HR.
 
  Findings from this study support the inclusion of the RRMT as part of the pulmonary rehabilitative program to assist patients with COPD in adapting to the negative psychological and physiological responses of distress.

  To develop a simulation-based psychological first aid (PFA) education program for disaster relief workers and verify its impact on their PFA knowledge, PFA performance competence, and self-efficacy.
 
  Relief workers should be provided with systematic education on their required knowledge and skills; however, PFA training for relief workers is lacking, which results in ineffective mental health support during disaster situations.
 
  This study adopted a non-equivalent control group pre-posttest quasi-experimental design. Thirty relief workers from mental health welfare centers in Seoul and Gyeonggi Province participated. The experimental group received a PFA lecture, a simulation-based PFA education program, and access to the Psychological Life Support (PLS) mobile application, which provides information on disaster situations and PFA techniques. The comparison group received a PFA lecture. The control group was provided with self-learning PFA materials.
 
  Among the three groups, the experimental group showed the greatest improvement in PFA knowledge, PFA performance competence, and self-efficacy from pretest to posttest, which was statistically significant.
