Strain UCMJ was isolated from the choana of a jackass penguin (Spheniscus demersus) with recurrent mucocaseous choanal discharge. Isolation of this mycoplasma expands the known range of species hosting mycoplasmas. The name Mycoplasma sphenisci sp. nov. is proposed for this new species, for which strain UCMJ is the type strain. 相似文献

This report describes a short, on-plate formic acid (FA) extraction method for the identification of clinical yeast isolates using matrix-assisted laser desorption ionization–time-of-flight mass spectrometry (MALDI-TOF MS). A total of 41.1% (78/190) and 63.7% (121/190) of yeasts were identified using species log score thresholds of >2.0 and >1.9, respectively. Overall, 97.4% (185/190) of yeasts were identified in combination with conventional FA extraction. 相似文献

Hemolytic anemia after mitral repair and annuloplasty ring placement is very uncommon, and rarely described. The case is presented of a 53-year-old woman who developed severe mitral regurgitation and transfusion-dependent hemolytic anemia following mitral valve repair with a Carpentier-Edwards annuloplasty ring, which included transposition of chordae tendineae from the posterior leaflet to the anterior leaflet. Transesophageal echocardiography suggested that the transposed chordae tethered the anterior leaflet, causing malcoaptation of the leaflets. This resulted in central regurgitation divided by the chordae tendineae, producing two turbulent flow jets causing hemolysis. At reoperation, these chordae were removed and two longer Gortex neochordae to the anterior leaflet were placed with subsequent resolution of the anemia. To the authors' knowledge, this is the first case of hemolytic anemia caused by transposed mitral valve chordae tendineae from the posterior to the anterior leaflet. 相似文献

Background: The surge in the incidence of obesity and being overweight demands new options to extend the reach of weight‐loss interventions. Mobile phones provide a medium for reaching large numbers of people in a cost‐effective manner. The present study aimed to explore the potential for weight‐loss interventions to be delivered via mobile phone. Methods: A mixed methods approach was employed. A telephone survey was conducted with 306 randomly selected participants, and 10 focus groups were undertaken with 54 purposively selected participants. The telephone survey comprised questions exploring the nature and acceptability of any potential weight‐loss programme that might be delivered via mobile phones. The focus groups were conducted to explore issues of acceptability in more depth than was possible in the survey. Results: Two‐thirds of participants reported support for a mobile phone weight‐loss intervention, with greater levels of support amongst younger age groups and rural Māori (the indigenous population in New Zealand). Participants liked the idea of ready access to weight‐loss information, and associated feedback and encouragement. The results suggest that interventions would need to include aspects of social support, use tailored and personalised content, and be practical and relevant so that they appeal to consumers. Appropriate methods of providing social support using a mobile phone require further exploration. Conclusions: Mobile phones may provide a novel but acceptable way to deliver a weight‐loss intervention. They have the potential to be automatically personalised and tailored to the needs of the individual, at the same time as being delivered at a population level. 相似文献

The aim of this study was to investigate the difference between sitting and standing passive urethral pressure measurements, and to determine the accuracy of urethral pressure profilometry in each position. Urethral pressure profilometry was performed in the sitting and standing position in 98 women. Stress incontinence due to urethral sphincter incompetence was demonstrated in 59 of whom 6 also had detrusor instability. The others were normal volunteers (7), women with a normal cystometrogram (23), and women with detrusor instability (9). MUCP tended to be higher in the standing than the sitting position but this did not reach statistical significance. Urethral lengthening appeared to occur on standing with a mean increase of FUL of 5 mm on standing. For both FUL and MUCP, there was a wide variation in the difference between sitting and standing values. There was poor reproducibility of measurements of MUCP and FUL in the standing position, limiting its clinical applicability. The difference between sitting and standing MUCP and FUL was not affected by age, parity, weight, height, BMI, or oestrogen status. In women with genuine stress incontinence, there was less difference between sitting and standing MUCP, but this explained only a small part of the variability. The increase in FUL in the standing position was unaffected by diagnosis. 相似文献

The effects of crystalloid and colloid infusions on coagulation measured by
thrombelastography (TEG) present a confused picture. The influence of
environmental factors may explain the disparity between previous studies.
We studied two groups of 20 women presenting at term for elective Caesarean
section. In the first group, TEG analysis was performed before and after
infusion of Gelofusine 500 ml over 15 min. The second group was treated in
the same way except that subjects did not receive fluid. We found
significant changes in r and k values in both groups, suggesting enhanced
coagulation. As hypercoagulable changes were also seen in the group that
did not receive fluid preload, the hypothesis that moderate haemodilution
causes hypercoagulability must be questioned. The influence of
environmental factors can explain differences reported between in vivo and
in vitro studies.

Outcomes of lower extremity amputations 总被引:2,自引:0,他引:2

In an effort to identify variables that could be used to predict outcomes of amputation, a cohort of 97 veteran amputees with a median age of 64 years who underwent 155 lower extremity procedures during 1984 was followed for 15 months. A high incidence of postoperative complication, revision, and mortality with poor quality of life confirm the serious prognosis of these individuals. Regression analyses indicated that peripheral vascular disease and prolonged preoperative hospitalization were associated with complications. Preoperative gangrene and peripheral vascular disease were associated with the need for revision. Complications, a low body mass index, and multiple diseases were related to death. Those with multiple diseases and extensive atherosclerosis were less likely to walk. Ability to perform activities of daily living was the most important predictor of quality of life. Patients at higher risk for these adverse outcomes need to be identified early in their hospital stay. The involvement of the patient or his or her surrogate in decisions regarding the course of treatment and the level of amputation is essential. 相似文献
