Scan time reduction for readout-segmented EPI using simultaneous multislice acceleration: Diffusion-weighted imaging at 3 and 7 Tesla
Purpose:
Readoutâsegmented echoâplanar imaging (rsâEPI) can provide high quality diffusion data because it is less prone to distortion and blurring artifacts than singleâshot echoâplanar imaging (ssâEPI), particularly at higher resolution and higher field. Readout segmentation allows shorter echoâspacing and echo train duration, resulting in reduced image distortion and blurring, respectively, in the phaseâencoding direction. However, these benefits come at the expense of longer scan times because the segments are acquired in multiple repetitions times (TRs). This study shortened rsâEPI scan times by reducing the TR duration with simultaneous multislice acceleration.
Methods:
The blippedâCAIPI method for slice acceleration with reduced gâfactor SNR loss was incorporated into the diffusionâweighted rsâEPI sequence. The rsâ and ssâEPI sequences were compared at a range of resolutions at both 3 and 7 Tesla in terms of image fidelity and diffusion postprocessing results.
Results:
Sliceâaccelerated clinically useful traceâweighted images and tractography results are presented. Tractography analysis showed that the reduced artifacts in rsâEPI allowed better discrimination of tracts than ssâEPI.
Conclusion:
Slice acceleration reduces rsâEPI scan times providing a practical alternative to diffusionâweighted ssâEPI with reduced distortion and high resolution. Magn Reson Med 74:136â149, 2015
Strain driven fast osseointegration of implants
BACKGROUND: Although the bone's capability of dental implant osseointegration has clinically been utilised as early as in the Gallo-Roman population, the specific mechanisms for the emergence and maintenance of peri-implant bone under functional load have not been identified. Here we show that under immediate loading of specially designed dental implants with masticatory loads, osseointegration is rapidly achieved. METHODS: We examined the bone reaction around non- and immediately loaded dental implants inserted in the mandible of mature minipigs during the presently assumed time for osseointegration. We used threaded conical titanium implants containing a titanium2+ oxide surface, allowing direct bone contact after insertion. The external geometry was designed according to finite element analysis: the calculation showed that physiological amplitudes of strain (500â3,000 ustrain) generated through mastication were homogenously distributed in peri-implant bone. The strain-energy density (SED) rate under assessment of a 1 Hz loading cycle was 150 Jm-3 s-1, peak dislocations were lower then nm. RESULTS: Bone was in direct contact to the implant surface (bone/implant contact rate 90%) from day one of implant insertion, as quantified by undecalcified histological sections. This effect was substantiated by ultrastructural analysis of intimate osteoblast attachment and mature collagen mineralisation at the titanium surface. We detected no loss in the intimate bone/implant bond during the experimental period of either control or experimental animals, indicating that immediate load had no adverse effect on bone structure in peri-implant bone. CONCLUSION: In terms of clinical relevance, the load related bone reaction at the implant interface may in combination with substrate effects be responsible for an immediate osseointegration state
The burden of peripheral intravenous catheters in older hospital inpatients : a national cross-sectional study part of the One Million Global Peripheral Intravenous Catheters Collaboration
Objectives: To investigate the burden of peripheral intravenous catheters (PIVCs) in older hospitalised patients. Methods: A cross-sectional prospective observational study (2014/2015) to describe the characteristics, indications and outcomes of PIVCs among patients aged â„65 from 65 Australian hospitals. Results: Amongst 2179 individual PIVCs (in 2041 patients, mean age 77.6 years, 45% female, 58% in NSW), 43% were inserted by doctors and 74% used that day, meaning 25% were âidleâ. Overall, 18% (393/2179) exhibited signs of PIVC-related complications. Most commonly exhibited PIVC-related complications were tenderness (4.1%) and local redness (1.8%). Nearly one in three (29.1%) dressings was soiled, loosened or had come off, and only 36.8% had the time and date documented on the dressing. Both infusing IV medications (aOR 1.74, 95% CI 1.28â2.38, p 84 years) was independently associated with lower likelihood of a high score (aOR 0.71, 95% CI 0.54â0.94, p = 0.02). Conclusions: Given 1 in 5 PIVCs were identified with having complications, further research should focus on optimising PIVC use in older patients
Epidemiology of pleural empyema in English hospitals and the impact of influenza
Pleural empyema represents a significant healthcare burden due to extended hospital admissions and potential requirement for surgical intervention. This study aimed to assess changes in incidence and management of pleural empyema in England over the past 10 years and the potential impact of influenza on rates. Hospital Episode Statistics data were used to identify patients admitted to English hospitals with pleural empyema between 2008 and 2018. Linear regression was used to analyse the relationship between empyema rates and influenza incidence recorded by Public Health England. The relationship between influenza and empyema was further explored using serological data from a prospective cohort study of patients presenting with pleural empyema. Between April 2008 and March 2018 there were 55 530 patients admitted with pleural empyema. There was male predominance (67% versus 33%), which increased with age. Cases have increased significantly from 4447 in 2008 to 7268 in 2017. Peaks of incidence correlated moderately with rates of laboratoryconfirmed influenza in children and young adults (r=0.30). For nine of the 10 years studied, the highest annual point incidence of influenza coincided with the highest admission rate for empyema (with a 2-week lag). In a cohort study of patients presenting to a single UK hospital with pleural empyema/ infection, 24% (17 out of 72) had serological evidence of recent influenza infection, compared to 7% in seasonally matched controls with simple parapneumonic or cardiogenic effusions (p<0.001). Rates of empyema admissions in England have increased steadily with a seasonal variation that is temporally related to influenza incidence. Patient-level serological data from a prospective study support the hypothesis that influenza may play a pathogenic role in empyema development

Molecular structures of the basic copper arsenate minerals olivenite, cornubite, cornwallite, and clinoclase were studied using a combination of infrared emission spectroscopy and Raman spectroscopy. Infrared emission spectra of the basic copper arsenates were obtained over the temperature range 100 to 1000°C. The IR emission spectra of the four minerals are different, in line with differences in crystal structure and composition. The Raman spectra are similar, particularly in the OH-stretching region, but characteristic differences in the deformation regions are observed. Differences are also observed in the arsenate stretching and bending regions. Infrared emission studies show that the minerals are completely dehydroxylated by 550°C
