Chemotaxis, chemokinesis and cellular orientation were measured for unstimulated and 10(-7) n-formyl methionyl leucyl phenylalanine (F-met-leu-phe) stimulated polymorphonuclear leucocytes (PMNS) of nine patients with recent 10-80 per cent burns using a computer-assisted image analysis technique. The technique records PMN movement, as viewed with a phase-contrast microscope on videotapes, and then uses computer programs to calculate the speed and direction of up to 50 PMNS over a 5-min period. Orientation was determined visually. Cellular adherence was also measured by attachment methods. PMNS from burn patients were slower (av. speed 16.8 microns/min), responded less well to F-met-leu-phe (av. speed 20.9 microns/min, av. McCutcheon index 0.32), were less often oriented towards the chemoattractant (av. 39 per cent) and were more adherent (av. 50 per cent) than control cells (av. speed 21.8 microns/min; av. speed F-met-leu-phe 32.2 microns/min; McCutcheon index 0.61; oriented 59 per cent adherent; 16 per cent). Thus PMNS from burn patients orient less well, are significantly slower and have less directionality in response to a chemoattractant, and are more adherent suggesting activation.  相似文献

ObjectiveThe clinical presentation of coeliac disease has changed and patients are often overweight at diagnosis. There is concern that patients might gain further weight while on a gluten-free diet (GFD). The aim of the study was to evaluate the impact of a GFD on the body mass index (BMI) in a nationwide cohort of coeliac patients and to determine variables predictive of favourable or unfavourable BMI changes.MethodsWe prospectively investigated weight and disease-related issues in 698 newly detected adults diagnosed due to classical or extraintestinal symptoms or by screening. BMI at diagnosis and after one year on a GFD were assessed and compared with that in the general population.ResultsAt diagnosis, 4% of subjects were underweight, 57% normal, 28% overweight and 11% obese. On a GFD, 69% of underweight patients gained and 18% of overweight and 42% of obese lost weight; in the rest BMI remained stable. Changes were similar in both symptom- and screen-detected patients. The coeliac group had a more favourable BMI pattern than the general population. Favourable BMI changes were associated with subjects' self-rated expertise on GFD and young age at diagnosis, but not dietary counselling received.ConclusionsBMI improved similarly in screen- and symptom-detected coeliac disease patients on a GFD.  相似文献

The aim of this national cross‐sectional study was to explore the prevalence of pressure injuries and incidence of hospital‐acquired pressure injuries, and the relating factors in somatic‐specialised inpatient care in Finland. The study was conducted in 16 (out of 21) Finnish health care organisations offering specialised health care services. Data were collected in 2018 and 2019 from adult patients (N = 5902) in inpatient, emergency follow‐up, and rehabilitation units. Pressure injury prevalence (all stages/categories) was 12.7%, and the incidence of hospital‐acquired pressure injuries was 10%. Of the participants, 2.6% had at least one pressure injury at admission. The risk of hospital‐acquired pressure injuries was increased for medical patients with a higher age, the inability to move independently, mode of arrival, being underweight, and the absence of a skin assessment or pressure injury risk assessment at admission. For surgical patients, the risk was associated with the inability to move independently, mode of arrival, and lack of skin assessment at admission, while being overweight protected the patients. Overall, medical patients were in greater risk of hospital‐acquired pressure injuries than the surgical patients. An assessment of the pressure injury risk and skin status should be carried out more systematically in Finnish acute care hospitals.  相似文献

BACKGROUND AND OBJECTIVE: To demonstrate the long-term efficacy and safety of pramipexole for Restless Legs Syndrome (RLS) using physician and patient RLS ratings, along with subjective assays of sleep parameters, in a 26-week, open-label trial. PATIENTS AND METHODS: Among 107 Finnish adults with moderate to severe RLS, pramipexole initiated at 0.125 mg/day was titrated to a maximum 0.75 mg/day. Efficacy evaluations included the International RLS Study Group Rating Scale (IRLS), Patient Global Impression (PGI) scale, Clinical Global Impressions-Improvement (CGI-I) scale, Epworth Sleepiness Scale (ESS), and Short Form-36 (SF-36) Health Survey. Subjective Sleep Quality was assessed by patient ratings of sleep and morning tiredness. Safety was documented by Adverse Events reported in >5% of patients. RESULTS: The mean reduction in IRLS score was 73.5% (P<0.05). The IRLS responder rate, defined by score reduction of >or= 50%, was 81.3%. On the PGI scale, 89.7% of patients rated themselves as "very much" or "much" better. By CGI-I assessment, 94.8% of patients were considered either "very much" or "much" improved. Mean ESS score showed a modest but statistically significant reduction (P<0.05) within the normal range, indicating that long-term pramipexole did not increase daytime sleepiness. On the SF-36 all 8 domains showed improvement, 5 of them statistically significant (P<0.05) and 4 of these 5 (role-physical, bodily pain, vitality, and role-emotional) by >10 points on a 100-point scale. Subjective Sleep Quality also improved. The most frequent Adverse Events were influenza (17.8%), headache (15.0%), and fatigue (10.3%). CONCLUSION: Pramipexole is well tolerated and effective for long-term treatment of RLS.  相似文献

The glial cell-derived neurotrophic factor (GDNF) precursor contains several putative sites for prohormone convertase-mediated excision of short peptides. Here, we show that one of the predicted peptides, named BEP (brain excitatory peptide), induces a substantial increase in the synaptic excitability in rat CA1 pyramidal neurons. The excitation is sensitive to N-ethylmaleimide, suggesting involvement of a G-protein-coupled receptor.  相似文献

Ovarian adult‐type granulosa cell tumors (AGCTs) require prolonged follow‐up, but evidence regarding the optimal follow‐up marker is lacking. The objective of our study was to validate the clinical usefulness of serum anti‐Müllerian hormone (AMH) and the current marker inhibin B as single and combined markers of AGCTs. We conducted a longitudinal, partially prospective cohort study of 123 premenopausal and postmenopausal AGCT patients with a median follow‐up time of 10.5 years (range 0.3–50.0 years). Serum AMH and inhibin B levels were measured from 560 pretreatment and follow‐up serum samples by using immunoenzymometric assays. We found that serum AMH and inhibin B levels were significantly elevated in patients with primary or recurrent AGCTs. The levels of both markers positively correlated to tumor size (p < 0.05). AMH and inhibin B performed similarly in receiving operator characteristic analyses; area under the curve (AUC) values were 0.92 [95% confidence interval (CI) 0.88–0.95] for AMH, and 0.94 (95% CI 0.90–0.96) for inhibin B. AMH was highly sensitive (92%) and specific (81%) in detecting a macroscopic AGCT. However, in AUC comparison analyses, the combination of the markers was superior to inhibin B alone. In conclusion, serum AMH is a sensitive and specific marker of AGCT, and either AMH or inhibin B can be monitored during follow‐up. However, combining AMH and inhibin B in AGCT patient follow‐up improves the detection of recurrent disease.  相似文献
