A 39-year-old man presented with progressive visual loss in both eyes. His past medical history was remarkable for biopsy-proven bilateral adrenal phaeochromocytomas. Ophthalmoscopy revealed an optic nerve head angioma and macular lipid exudates in the right eye and a regressed optic nerve head angioma in the left eye. A fluorescein angiogram revealed a lobulated pattern of leakage and venous staining from the optic nerve head angioma. Brain and orbital magnetic resonance imaging showed haemangioblastomas of the right intraorbital and left paraclinoid optic nerves and in the left cerebellopontine angle area. These findings were consistent with a clinical diagnosis of von Hippel-Lindau disease. 相似文献

Hospital census prediction has well-described implications for efficient hospital resource utilization, and recent issues with hospital crowding due to CoVID-19 have emphasized the importance of this task. Our team has been leading an institutional effort to develop machine-learning models that can predict hospital census 12 hours into the future. We describe our efforts at developing accurate empirical models for this task. Ultimately, with limited resources and time, we were able to develop simple yet useful models for 12-hour census prediction and design a dashboard application to display this output to our hospital’s decision-makers. Specifically, we found that linear models with ElasticNet regularization performed well for this task with relative 95% error of +/− 3.4% and that this work could be completed in approximately 7 months. 相似文献

Background
Health literacy and e-health literacy are important factors helping people shape awareness of health behaviours in different aspects, including sleep hygiene behaviours. Good sleep hygiene behaviours promote sleep quality and are beneficial to overall mental wellbeing.Objective
We aimed to examine if sleep hygiene behaviours may mediate the association between health literacy/e-health literacy and mental wellbeing.Methods
Adult Iranian subjects (n = 9775; mean [SD] age = 36.44 [11.97] years; 67.3% females) completed the Health Literacy Instrument for Adults, eHealth Literacy Scale, three items on sleep hygiene behaviour that have been used in prior research and the Short Warwick Edinburgh Mental Wellbeing Scale. Data were then subjected to structural equation modelling (SEM) including 500 bootstrapping resampling to examine whether sleep hygiene is a mediator in the relationship between health literacy/e-health literacy and mental wellbeing.Findings
Both health literacy and e-health literacy were significantly associated with mental wellbeing (r = .63 for health literacy and .39 for e-health literacy; p < .001) and sleep hygiene behaviours (r = .58 for health literacy and .36 for e-health literacy; p < .001). Sleep hygiene behaviours were significantly associated with mental wellbeing (r = .42; p < .001). Moreover, SEM that incorporated bootstrapping approaches indicated that sleep hygiene behaviours were significant mediators in the association between health literacy/e-health literacy and mental wellbeing.Conclusions
We conclude that health literacy and e-health literacy are associated with mental health wellbeing in the Iranian population. Additionally, the association could be mediated via sleep hygiene behaviours.Patient or Public Contribution
The study was co-designed with healthcare providers from the vice-Chancellor's Office for Health Affairs of Qazvin University of Medical Sciences as equal partners. Moreover, the women's health volunteers were involved in the design of the study. 相似文献45.

The number of adolescents who use illicit drugs has increased dramatically. Adolescence is a critical period for brain development and maturation. The importance of the study of pain perception and the possible mechanisms involved is crystal clear. Up until now, there has been no evidence regarding the long-term effect of adolescence morphine administration on pain perception. The objective of the present study was to investigate long-lasting effect of adolescent morphine exposure on pain perception as well as analgesic response to a single dose of morphine injection. Adolescent and adult rats received morphine or saline, and then after 30 days of washout period, formalin test was performed. To evaluate morphine analgesia, in a separate group of animals, formalin test was performed after injection of a single dose of morphine during adulthood. The results demonstrated that the adolescent rats treated by morphine exhibited higher pain-related behaviors compared to the control group, while the same results were not observed in adult rats that had been treated by morphine. Moreover, there was no significant difference in analgesic response to a single dose of morphine between two experimental groups. This study demonstrates enduring effect of morphine exposure during adolescence on pain perception. 相似文献

In situ electrochemical activation as a new pre-treatment method is extremely effective for enhanced electrocatalytic performances for different applications. With the help of this method, in situ surface modification of electrocatalyst is achieved without using pre-made seeds or complex synthesis procedure. Herein, with the purpose of finding an in situ and simple electrochemical activation protocol, the green synthesis of Au/Pd nanoparticles (AuPd) by means of polyoxometalate (POM) is reported. Structural analysis of the AuPd nanohybrid unveil the Au-core/Pd-shell structure which surrounded by POM. We propose a novel cathodic electrochemical activation in phosphate buffer solution which can greatly boost the electrocatalytic activity of the as-prepared AuPd and Pd electrocatalyst not only for hydrogen evolution reaction (HER) as a model of electro-reduction, but also for methanol and ethanol electro-oxidation reaction (MOR & EOR). For the HER in 1 M NaOH solution, after the electrochemical activation, the needed potential to drive a geometrical current density of 10 mA cm−2 significantly decreases from – 400 mV vs. the reversible hydrogen electrode (RHE) to −290 mV vs. RHE. For the EOR and MOR, electrochemically activated AuPd realized 3.4- and 2.9- fold increase in mass current density (mA mgPd−1) with respect to the pristine AuPd electrocatalyst, respectively. In situ electrochemical activation as a new pre-treatment method is extremely effective for enhanced electrocatalytic performances for different applications. 相似文献

Background: Increased evidences have shown that unexplained recurrent spontaneous abortion (URSA) is associated with inflammatory responses and breakage of immunological autotolerance. Therefore, the balance between Th17 and Treg cells may elucidate the pathophysiology of URSA. Objective: To investigate the serum concentration of regulatory and inflammatory cytokines associated with Treg and Th17 in both normal and URSA females. Methods: Forty-six women with URSA and 28 non-pregnant control women with at least one successful pregnancy were included. Serum was obtained from both groups and stored at -70°C. The serum concentrations of IL-17, IL-21, IL-22, IL-10, and TGF-β were quantitatively determined by ELISA. Results: The levels of IL-17, IL-21, and IL-22 in sera were significantly higher (P<0.001, P=0.01 and P<0.001, respectively) and TGF-β serum concentration was significantly lower (P=0.02) in URSA women compared with normal controls. Conclusion: Our results suggest that enhancement in Th17-associated cytokine levels and reduction in TGF-β may be one of the factors involved in URSA. 相似文献
