Objective Lower limb amputation is common in war combat and armed conflict as well as in traumatic settings and presents a challenge for health care providers. The incorporation of advanced technologies, particularly virtual reality, presents an opportunity to address the main consequences of amputation, principally balance and gait. The aim of this study was to investigate the additional effect of virtual reality with a traditional rehabilitation exercise program on balance and gait in unilateral, traumatic lower limb amputees. Materials and Methods Thirty-two traumatic lower limb amputees, fulfilling a postfitting rehabilitation program at least 6 months ago, were recruited and randomly assigned into two identically sized groups; group C (control group) experiencing the traditional exercise program and group VR (virtual reality group) experiencing an addition of a virtual reality training. The intervention was conducted over 6 weeks at a rate of three sessions per week. Outcome measures assessed before and after 6 weeks were the Berg Balance Scale (BBS), Timed Up and Go (TUG) test, Dynamic Gait Index (DGI), and 6-minute walk test (6 MWT). MEK inhibitor Results Both interventions induced improvement in all measured parameters (P  0.05). Conclusion Virtual reality is a promising, amusing, and safe intervention for addressing balance and gait in unilateral, traumatic lower limb amputees.Objective The Köhler effect is a social-psychological group motivation gain phenomenon that has been successfully adapted to video-based exercise games (exergames) using human partners. This research then shifted to using software-generated partners (SGPs), providing greater flexibility and adaptability to manipulate the game environment to be most motivating for the user. However, recent SGP-based experiments have demonstrated a diminished motivation gain effect. Extending previous work with human-human partners, this experiment varied the perceived exercise ability of the SGP as a potential motivation gain effect moderator on the participant’s exercise persistence. Materials and Methods Male and female college students (n = 176; mean age, 21.5 years) completed two series of abdominal plank exercises using an exergame developed specifically for a previous Köhler study. Participants completed the exercises individually and, after a rest, were randomly assigned to complete the same exercises again alone or with one of three SGPs low ability discrepancy partner (LP), moderate ability discrepancy partner (MP), and high ability discrepancy partner (HP). Results A 2 (sex) × 4 (condition) analysis of covariance main effect for Condition was not significant after controlling for Block 1 times (P = 0.093). However, contrast estimates of plank persistence times between the MP condition and individual no-partner control were significant, P = 0.014, 95% confidence interval [4.34-37.68]. There were no other significant condition persistence differences. Conclusions A moderate discrepancy between the participant and the superior nonhuman partner is more motivating in a conjunctive task paradigm than exercising alone or with an SGP that is low or high in ability discrepancy.In situ instrumentation that can detect amino acids at parts-per-billion concentration levels and distinguish an enantiomeric excess of either d- or l-amino acids is vital for future robotic life-detection missions to promising targets in our solar system. In this article, a novel chiral amino acid analysis method is described, which reduces the risk of organic contamination and spurious signals from by-products by avoiding organic solvents and organic additives. Online solid-phase extraction, chiral liquid chromatography, and mass spectrometry were used for automated analysis of amino acids from solid and aqueous environmental samples. Carbonated water (pH ∼3, ∼5 wt % CO2 achieved at 6 MPa) was used as the extraction solvent for solid samples at 150°C and as the mobile phase at ambient temperature for chiral chromatographic separation. Of 18 enantiomeric amino acids, 5 enantiomeric pairs were separated with a chromatographic resolution >1.5 and 12 pairs with a resolution >0.7. The median lower limit of detection of amino acids was 2.5 μg/L, with the lowest experimentally verified as low as 0.25 μg/L. Samples from a geyser site (Great Fountain Geyser) and a geothermal spring site (Lemon Spring) in Yellowstone National Park were analyzed to demonstrate the viability of the method for future in situ missions to Ocean Worlds.Congenital hypothyroidism (CH) is an important cause of preventable intellectual disability. Implementation of CH neonatal screening programs leading to early treatment has improved cognitive outcome. However, more subtle cognitive impairments are still reported, and there is lack of clarity regarding factors that impact long-term cognitive outcome. Research to better understand these factors can lead to further improvements in the cognitive prognosis for these patients. The current study aimed to evaluate the cognitive performance of adolescents who were early-treated for primary permanent CH and possible associated variables. Neurocognitive evaluation was carried out in 66 adolescents, 11 to 16 years old 34 with CH and 29 paired controls. Intellectual quotient (IQ), verbal fluency, processing speed, executive functions, and memory were investigated. CH patients and control subjects were comparable regarding sex, age, schooling, family’s socioeconomic status and caregiver’s educational level. Both groups presented not only similar IQ scores but also equivalent performances regarding Perceptual Reasoning, Working Memory and Processing Speed index scores. Patients presenting different CH etiologies (dysgenesis and dyshormonogenesis) showed similar cognitive performance. Socioeconomic aspects along with the initial levothyroxine dose were the main variables to positively influence the cognitive performance, the family’s socioeconomic status having the strongest association with patients‘ cognitive skills.Background Intra-abdominal infection (IAI) is a wide range of intra-abdominal disease. Management involves empirical therapy and source control. Procalcitonin (PCT) has been suggested to assist in defining individual infection status and delivering individualized therapy. The aim of this study was to investigate the effects on patient outcomes of an early procalcitonin (PCT) assessment (in the emergency department [ED]) in patients with IAI. Methods This was a retrospective, mono-centric study evaluating consecutive patients admitted to the ED from 2015 to 2019 with diagnosis of IAI. According to whether there had been PCT determination in the ED, patients were divided into no ePCT determination (no-ePCT) and early PCT determination in the ED (ePCT). The primary endpoint was the intra-hospital mortality rate. Secondary endpoints were occurrence of major complications and length of hospital stay (LOS). The propensity score match (PSM) was generated using a logistic regression model on the baseline covariates considered to be potentially influencing the decision to determine PCT in the ED and confounding factors identified as significant at a preliminary statistical analysis with respect to in-hospital death.
