Item does not contain fulltext BACKGROUND: Sepsis is a leading cause of morbidity and mortality after surgery. Most studies regarding sepsis do not differentiate between patients who have had recent surgery and those without. Few data exist regarding the risk factors for poor outcomes in pediatric postsurgical sepsis. Our hypothesis is pediatric postsurgical, and medical patients with severe sepsis have unique risk factors for mortality. METHODS: Data were extracted from a secondary analysis of an international point prevalence study of pediatric severe sepsis. Sites included 128 pediatric intensive care units from 26 countries. Pediatric patients with severe sepsis were categorized into those who had recent surgery (postsurgical sepsis) versus those that did not (medical sepsis) before sepsis onset. Multivariable logistic regression models were used to determine risk factors for mortality. RESULTS: A total of 556 patients were included: 138 with postsurgical and 418 with medical sepsis. In postsurgical sepsis, older age, admission from the hospital ward, multiple organ dysfunction syndrome at sepsis recognition, and cardiovascular and respiratory comorbidities were independent risk factors for death. In medical sepsis, resource-limited region, hospital-acquired infection, multiple organ dysfunction syndrome at sepsis recognition, higher Pediatric Index of Mortality-3 score, and malignancy were independent risk factors for death. CONCLUSIONS: Pediatric patients with postsurgical sepsis had different risk factors for mortality compared with medical sepsis. This included a higher mortality risk in postsurgical patients presenting to the intensive care unit from the hospital ward. These data suggest an opportunity to develop and test early warning systems specific to pediatric sepsis in the postsurgical population.

Context The osteopathic medical school curriculum is unique because of the inclusion of training in osteopathic manipulative medicine (OMM). Interest in and use of OMM promotes cognitive training in diagnosing conditions, emotional training in the alleviation of pain, and physical training in the application of OMM. Osteopathic manipulative medicine may mitigate a reduction in empathy levels of medical students and explain why osteopathic medical students do not follow the declining pattern of empathy previously reported in allopathic medical students. Objective To examine whether favorable opinions of OMM are positively correlated with overall student empathy as well as the cognitive, emotional, and behavioral subcomponents of empathy. Methods Institutional review board approval was obtained to measure empathy in medical students attending the Midwestern University/Chicago College of Osteopathic Medicine for this cross-sectional study. The 20-item Jefferson Scale of Empathy medical student version (JSE-S) was distributed via email to first-year students at the beginning of the 2016-2017 academic year and at the end of the academic year to all students. Items were divided into cognitive, emotional, and behavioral categories. Items related to demographics, interest and use of OMM and the osteopathic philosophy, frequency of touch, and personality were also included in the survey. Data were analyzed using SPSS software and presented as mean (SEM). Statistical significance was set at P Results Of the 801 students the survey was sent to at the end of the 2016-2017 academic year, 598 students completed the survey, for a response rate of 75%. When accounting for the effect of gender with a multivariate analysis of covariance, there were no differences in empathy scores across school years. When empathy scores from first- and second-year students were combined and compared with combined third- and fourth-year students’ scores to examine the difference between empathy in students during academic and clinical training, a difference in the mean (SEM) JSE-S empathy score was noted (114.6 [0.7] and 112.0 [0.7], respectively; P=.01); however, the effect size was small (partial η2=0.01). Interest in OMM and the osteopathic philosophy were significantly associated with higher empathy scores (P2=0.08). Conclusion Interest in and use of OMM are associated with higher empathy scores and empathy subcomponents. Training and use of OMM should be examined as a mechanism contributing to the durability of empathy in the osteopathic medical profession.

To evaluate the efficacy of a self-administered cognitive training program for improving cognition in normal elderly persons.A multisite, randomized control, double-blind trial was conducted with 28 experimental participants (MCompared to the AC group, the EI group displayed significant gains on targeted executive (p = .002) and memory (p.001) composites, but not the emotion (p = .105) composite. Training-induced benefits were also observed for the EI group on untrained items within global cognition (BCRS, p = .002) and functional abilities (DAD, p.001; FRS, p = .042). The percentage of participants who showed reliable performance improvements was greater for the EI than AC on executive (55.5% vs. 12.5%), memory (55% vs. 19.5%) and functional (41% vs. 7.5%) ability. Participant recruitment and compliance rates were enhanced by the involvement of a physician.Results support the efficacy of self-directed cognitive training in reliably improving cognitive and functional abilities in normal older adults. While physicians are critical in enhancing the delivery of regimented treatment, the present study illustrates the potential for self-directed prophylactic training in deterring the development of cognitive decline.

Cognitive impairment is common in patients with pain. While symptoms of pain are effectively treated with osteopathic manipulative treatment (OMT), the cognitive complaint is vastly ignored. Pain-induced cognitive dysfunction can be severe and is particularly apparent in working memory and attention. There is good reason to expect cognitive responsiveness to OMT. Previous research has reported the effects of OMT on related psychiatric outcomes, including relief from depression and anxiety, suggesting that OMT may produce more cortical benefits than is currently thought. The rationale to link OMT to cognition comes from the tenets of osteopathic medicine: body unity, homeostasis, and the structure-function relationship. The present article provides background evidence to support the hypothetical link between OMT and cognitive benefits and proposes a physiological mechanism of how OMT could exert its effect on cognition. Research strategies are discussed to test the hypotheses that are generated from the proposed theoretical framework.

Contains fulltext : 200437.pdf (Publisher’s version ) (Closed access) OBJECTIVES: The impact of nutrition status on outcomes in pediatric severe sepsis is unclear. We studied the association of nutrition status (expressed as body mass index z score) with outcomes in pediatric severe sepsis. DESIGN: Secondary analysis of the Sepsis Prevalence, Outcomes, and Therapies study. Patient characteristics, ICU interventions, and outcomes were compared across nutrition status categories (expressed as age- and sex-adjusted body mass index z scores using World Health Organization standards). Multivariable regression models were developed to determine adjusted differences in all-cause ICU mortality and ICU length of stay by nutrition status. SETTING: One-hundred twenty-eight PICUs across 26 countries. PATIENTS: Children less than 18 years with severe sepsis enrolled in the Sepsis Prevalence, Outcomes, and Therapies study (n = 567). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Nutrition status data were available for 417 patients. Severe undernutrition was seen in Europe (25%), Asia (20%), South Africa (17%), and South America (10%), with severe overnutrition seen in Australia/New Zealand (17%) and North America (14%). Severe undernutrition was independently associated with all-cause ICU mortality (adjusted odds ratio, 3.0; 95% CI, 1.2-7.7; p = 0.02), whereas severe overnutrition in survivors was independently associated with longer ICU length of stay (1.6 d; p = 0.01). CONCLUSIONS: There is considerable variation in nutrition status for children with severe sepsis treated across this selected network of PICUs from different geographic regions. Severe undernutrition was independently associated with higher all-cause ICU mortality in children with severe sepsis. Severe overnutrition was independently associated with greater ICU length of stay in childhood survivors of severe sepsis.

Introduction Research in the field of the aging brain has evolved to the extent that it is now commonly understood that actively engaging in cognitive tasks provides the potential of being beneficial in affecting the trajectory of age-related cognitive decline. What remains to be examined is the extent, and type, of program required to effect change in aging cognitively impaired individuals. Methods To address this issue, a cognitive program focusing on the use of visuospatial (VS)/visuomotor (VM) elements was applied to a group of six older individuals with identified progressive cognitive impairments. It was hypothesized that using tasks with VS and VM components may be beneficial in supporting overall brain performance, and subsequently assist individuals to perform well in various cognitive and behavioral tasks. Results Results showed that on many evaluative measures individuals remained stable, or improved in performance with medium-to-large effect sizes (e.g., 0.3–1.0). Thus, in a cognitively impaired population sample where decline would be the norm, our participants improved or remained stable. Conclusion The novel application of a VS/VM training program shows promise in addressing global cognitive decline, by targeting a brain area susceptible to early disruptions and providing it with additional and ongoing stimulative tasks in an effort to bolster its functioning and subsequently overall brain functioning.

The stability constants for the formation of NpO2L and NpO2HL (L = AMP, ADP, or ATP) have been measured potentiometrically in solutions of 0.10 M (NaClO4) ionic strength and at 25°C. The order of complexation strength was ATP4− > ADP3− > AMP2− as expected for systems with dominant ionic interactions. The results obtained were compared to complexation of the alkaline earths and trivalent lanthanide ions by the same series of ligands.

Background There is a paucity of information regarding visuospatial (VS) and visuomotor (VM) task performance in patients with chronic right fronto-parietal lobe stroke, as the majority of knowledge to date in this realm has been gleaned from acute stroke patients. The goal of this paper is to determine how VS and VM performance in chronic stroke patients compare to the performance of healthy participants. Methods Nine patients with stroke involving the right fronto-parietal region were evaluated against match controls on neuropsychological tests and a computerized visuomotor assessment task. Results Initial evaluation indicated that performance between participant groups were relatively similar on all measures. However, an in-depth analysis of variability revealed observable differences between participant groups. In addition, large effect sizes were also observed supporting the theory that using only conventional examination (e.g., p-values) measures may result in miss-identifying crucial stroke-related differences. Conclusion Through conventional evaluation methods it would appear that the chronic stroke participants had made significant functional gains relatively to a control group many years post-stroke. It was shown that the type of evaluation used is essential to identifying group differences. Thus, supplementary methods of evaluation are required to unmask the true functional ability of individuals many years post-stroke.

A light microscopic study was carried out on testicular aging in the Wistar rat at the ages of 7, 12, 24, 40, 56, 72, 104, and 124 weeks. The following tissular modifications were observed: a progressive decrease in capillary density, a gradually reduced spermatogenic production, and a progressive increase of degenerating tubular areas. The following two questions were raised: (1) Are the vascular modifications responsible for the other alterations? (2) Do the anomalies inducing a decreased number of spermatozoa simultaneously lead to genetic alterations in the morphologically normal spermatozoa with fertilizing ability? This question is particularly interesting owing to our current knowledge of the consequences of the father's age on offspring.
