Introduction : Serious games are interactive and entertaining digital software with an educational purpose, and they are increasingly being used in undergraduate medical education. Effective serious games attempt to form positive mood in order to encourage players to continue the play, leading to increased interest in gameplay and satisfaction as well as better academic performances. Aim: To determine the medical students’ satisfaction, situational and individual interest during a serious game. Methods : This was a prospective study performed during a 2-year period (2018-2019 and 2019-2020). A total of 108 third-year medical students participated in this study. Students were asked to play a serious game on a computer for 20 minutes. A set of questionnaires containing evaluation grids to measure the satisfaction and interest was given to students. The effectiveness of the game was assessed using pre and post-tests. Results : Following the exclusion criteria of students due to missing data, complete data were available for 97 students. Satisfaction and interest experienced by the students were high. The median of the game performance of students was 418, 04 points. There was a positive relationship between ease of use and game performance.There was a negative correlation between the three scales of interest and game performance.There was a significant difference between the mean scores of pre-tests and post-tests (p<0.01). Conclusion: The results of this study suggest the potentials of serious game on medical student’s satisfaction, interest and learning achievement. 相似文献

Bacteraemia is a leading cause of morbidity in sickle cell anaemia (SCA), but information from studies in Africa is limited. We evaluated 890 admissions from 648 SCA patients at a tertiary hospital in Tanzania. Bacteraemia was present in 43 admissions (4·8%); isolates included Staphylococcus aureus (12/43; 28%), non‐Typhi Salmonella (9/43; 21%), Streptococcus pneumoniae (3/43; 7%) and Salmonella Typhi (2/43; 5%). Compared to SCA patients without bacteraemia, SCA patients with bacteraemia had significantly lower haemoglobin [71 g/l vs. 62 g/l, odds ratio 0·72 (95% confidence interval 0·56–0·91), P < 0·01]. Further exploration is needed of the relationship between anaemia and bacterial infections in SCA in Africa. 相似文献

Spectral Doppler of the Hepatic Veins in Noncardiac Diseases: What the Echocardiographer Should Know 下载免费PDF全文
Bahaa M. Fadel M.D. Khadija Alassas M.D. Aysha Husain M.D. Ziad Dahdouh M.D. Giovanni Di Salvo M.D. 《Echocardiography (Mount Kisco, N.Y.)》2015,32(9):1424-1427
In most instances, the flow profile in the hepatic veins (HVs) reflects the fluctuation of pressure within the right atrium. Thus, interrogation of blood flow in the HVs is highly useful for the evaluation of right heart hemodynamics and has become an integral part of any routine echocardiographic examination. However, flow in the HVs is also affected by the state of the liver parenchyma and by the fluctuation of pressure within the thoracic cavity. Therefore, liver and pulmonary pathologies influence the flow pattern in the HVs and may lead to its dissociation from right heart hemodynamics. Echocardiographers should familiarize themselves with the findings on HV Doppler in noncardiac diseases to avoid misinterpretation and incorrect diagnosis. 相似文献

ERM (ezrin, radixin moesin) proteins in lymphocytes link cortical actin to plasma membrane, which is regulated in part by ERM protein phosphorylation. To assess whether phosphorylation of ERM proteins regulates lymphocyte migration and membrane tension, we generated transgenic mice whose T-lymphocytes express low levels of ezrin phosphomimetic protein (T567E). In these mice, T-cell number in lymph nodes was reduced by 27%. Lymphocyte migration rate in vitro and in vivo in lymph nodes decreased by 18% to 47%. Lymphocyte membrane tension increased by 71%. Investigations of other possible underlying mechanisms revealed impaired chemokine-induced shape change/lamellipod extension and increased integrin-mediated adhesion. Notably, lymphocyte homing to lymph nodes was decreased by 30%. Unlike most described homing defects, there was not impaired rolling or sticking to lymph node vascular endothelium but rather decreased migration across that endothelium. Moreover, decreased numbers of transgenic T cells in efferent lymph suggested defective egress. These studies confirm the critical role of ERM dephosphorylation in regulating lymphocyte migration and transmigration. Of particular note, they identify phospho-ERM as the first described regulator of lymphocyte membrane tension, whose increase probably contributes to the multiple defects observed in the ezrin T567E transgenic mice. 相似文献

Purpose
FDG PET has been suggested to have predictive value in the prognosis of oesophageal carcinoma. However, the retrospective studies reported in the literature have shown discordant results. Additionally, only four studies have evaluated FDG PET during chemoradiotherapy (CRT) in patients with different histological lesions. The purpose of this study was to investigate the predictive value of FDG PET performed early during CRT (on day 21) in a population of patients with oesophageal squamous cell carcinoma.Methods
Included in this prospective study were 57 patients with a histological diagnosis of squamous cell carcinoma of the oesophagus. Of these 57 patients, 48 (84 %) were evaluated (aged 63?±?11 years; 44 men, 4 women). Each patient underwent FDG PET (4.5 MBq/kg) before CRT, according to the Herskovic protocol (t0; PET1) and on day 21?±?3 from the start of CRT (d21; PET2). The response assessment included a clinical examination, CT scan or FDG PET and histological analysis 3 months and 1 year after PET1. The patients were classified as showing a complete response (CR) or a noncomplete response. A quantitative analysis was carried out for PET1 and PET2 using the following parameters: SUVmax, SUVmean (with SUVmean40 as the 3-D volume at an SUVmax threshold of 40 % and SUVmeanp as that defined by a physician), tumour volume (TV, with TV40 defined as the TV at 40 % of SUVmax, and TVp as that defined by a physician); and the total lesion glycolysis (TLG, SUVmean × TV, with TLG40 defined as the TLG at 40 % of SUVmax, and TLGp as that defined by a physician). The differences in responses at 3 months and 1 year between PET1 (t0) and PET2 (d21) were assessed in terms of variations in SUV, TV and TLG using a repeated measures of variance (ANOVA).Results
SUVmax, SUVmean and TLG decreased significantly between PET1 (t0) and PET2 (d21; p?<?0.0001). The TV significantly decreased only when assessed as TVp (p?=?0.02); TV40 did not decrease significantly. With respect to the predictive value of PET1, only TV40_1 and TVp_1 values, and therefore TLG40_1 and TLGp_1, but not the SUV values, were significantly lower in patients with CR at 3 months. SUVmax1, TVp_1 and TLGp_1 were significantly lower in patients with CR at 1 year. With respect to the predictive value of PET2, only TV40_2 and TVp_2 values, and therefore TLG40_2 and TLGp_2, but not the SUV values, were significantly lower in patients with CR at 3 months. None of the PET2 parameters had significant value in predicting patient outcome at 1 year. The changes in SUVmax, TV40, TVp, TLG40 and TLGp between PET1 and PET2 had no relationship to patient outcome at 3 months or 1 year.Conclusion
This prospective, multicentre study performed in a selected population of patients with oesophageal squamous cell cancer demonstrates that the parameters derived from baseline PET1 are good predictors of response to CRT. Specifically, a high TV and TLG are associated with a poor response to CRT at 3 months and 1 year, and a high SUVmax is associated with a poor response to CRT at 1 year. FDG PET performed during CRT on day 21 appears to have less clinical relevance. However, patients with a large functional TV on day 21 of CRT have a poor clinical outcome (ClinicalTrials.gov NCT 00934505). 相似文献328.
This article provides information concerning issues related to the care of individuals who are visually impaired. Issues reviewed include determining who should be referred for vision rehabilitation services, Charles Bonnet syndrome, visual acuity, contrast sensitivity and visual field testing along with Useful Field of View testing. This article also discusses technology advances that can enhance the visual functioning of individuals who are visually impaired, including how these advances can help drivers with visual impairments to continue to safely operate motor vehicles, at least on a limited basis. Finally, resources that are available to both encourage and motivate patients to take advantages of vision rehabilitation services are reviewed. 相似文献

Syringocystadenoma Papilliferum (SCAP) is a benign adnexal tumor. Most of the cases present with a solitary lesion in the head and neck region at birth or in early childhood. In fact, only two cases of SCAP on the lower leg have been reported in the literature. We report an atypical case by its location and its clinical aspect. 相似文献
