Background

High trait anxiety (HTA) causes an impaired quality of life (QOL) and fatigue in women with breast cancer (BC) and benign breast disease (BBD). We examined whether the lowered QOL was determined solely by the personality characteristic HTA or by the combination of personality and diagnosis.

Methods

In a prospective longitudinal study, women with BC (n = 152), BBD (n = 205), or gallstone disease (GD) before laparoscopic cholecystectomy (n = 128) were included. Questionnaires concerning trait anxiety (baseline), fatigue, and QOL were completed at baseline and at 6 months. Multivariate linear regression analysis was performed to analyze the predictors for QOL at 6 months.

Results

At 6 months QOL scores were increased in the GD group, especially in women without HTA. For women without HTA, in the BBD group the scores for fatigue and physical QOL had improved at 6 months, whereas in the BC group physical QOL and fatigue was impaired. Women with HTA scored unfavorably on fatigue and QOL. HTA was the most important factor influencing QOL.

Conclusions

The course of QOL and fatigue during follow-up were significantly different for each diagnosis. Particularly HTA had a negative impact on QOL and fatigue. Especially the combination HTA and BC caused impaired QOL and fatigue. We recommend identifying women with BC and HTA and offer them a tailor-made follow-up protocol.  相似文献

Background

Left ventricular dysfunction is an important co-morbidity of end-stage renal disease (ESRD) and is associated with a poor prognosis in the adult population. In pediatric ESRD, left ventricular function is generally well preserved, but limited information is available on early changes in myocardial function. The aim of this study was to investigate myocardial mechanics in pediatric patients with ESRD using speckle-tracking echocardiography (STE).

Methods

Echocardiographic studies, including M-mode, tissue Doppler imaging (TDI) and STE, were performed in 19 children on dialysis, 17 transplant patients and 33 age-matched controls. Strain measurements were performed from the apical four-chamber and the short axis view, respectively.

Results

The interventricular and left ventricular posterior wall thickness was significantly increased in dialysis and transplant patients compared to healthy controls. No significant differences were found in shortening fraction, ejection fraction and systolic tissue Doppler velocities. Dialysis and transplant patients had a decreased mean longitudinal strain compared to healthy controls, with a mean difference of 3.1 [95 % confidence interval (CI) 2.0–4.4] and 2.7 (95 % CI 1.2–4.2), respectively. No differences were found for radial and circumferential strain.

Conclusions

Speckle-tracking echocardiography may reveal early myocardial dysfunction in the absence of systolic dysfunction measured by conventional ultrasound or TDI in children with ESRD.

Adenocarcinomas of the kidney are rare childhood tumors. Only 30 cases with chromosomal abnormalities have been reported, and neither their karyotypic characteristics nor the molecular mechanisms behind their pathogenesis are clear, except for a special group of papillary tumors characterized by X-chromosome abnormalities. We have cytogenetically analyzed short-term cultured cells from two pediatric renal carcinomas, one papillary, and one chromophobe renal cell carcinoma, revealing the following karyotypes: 58-60,XX,-X,-1,+7,-8,-9,-11,-14,-15,+17,-18,-19,-21,-22 and 36,X,-X,-1,-2,-5,-6,-9,-10,-13,-17,-21/37,idem,+r/36,idem,-14,+1-2r, respectively. The findings indicate that subsets of pediatric renal cell carcinoma show karyotypes that are similar to their adult counterparts.  相似文献

Fibrosarcoma of bone is a rare malignant tumor accounting for less than 5% of all primary malignant bone neoplasms. There is very limited knowledge regarding the molecular genetics of this tumor, and there are no cytogenetic data available. In the present study, a fibrosarcoma deriving from the left iliac bone of a 10-year-old girl was characterized using cytogenetics, fluorescence in situ hybridization (FISH), and whole genome tiling resolution array comparative genomic hybridization (CGH). Cytogenetic and FISH analyses revealed a ring chromosome 6 as the sole acquired aberration, a finding corroborated by array CGH. The ring formation, however, did not result in any gain of genetic material. Nor did the breakpoints in 6p25 and 6q14 seem to affect any known gene loci in such a way that the ring formation could have resulted in the creation of a fusion gene or in the exchange of regulatory sequences. Thus, a reasonable interpretation of the pathogenetic significance of the ring formation would be that it resulted in the loss of one or more putative tumor suppressor gene loci distal to the two breakpoints.  相似文献

In 54 patients with interstitial lung diseases and no signs of airway obstruction we measured lung volumes, maximal expiratory flows, diffusing capacity (DLCO), total respiratory resistance (Rrs) and reactance (Xrs) between 4 and 26 Hz by means of the forced oscillation technique. In all patients DLCO was less than 75% of the expected value. Patients were classified into two groups depending on total lung capacity (TLC): group A with TLC less than 80% of expected, and group B with TLC of 80% or more. Group A demonstrated a decrease of Xrs especially at low frequencies, with small, not significant changes in Rrs. In the patients in this group with the lowest values of TLC (less than 50%), we observed an increase of Rrs at low frequencies causing a negative frequency dependence of Rrs. In group B no distinct changes of Rrs and Xrs occurred. Canonical correlation analysis between routine lung function data and forced oscillation parameters, showed tight correlations between TLC in absolute value or VC in percent of the predicted value on the one hand and average level of Xrs and average slope of Xrs (and Rrs) vs frequency curves on the other hand. Measurements of lung mechanics in five additional patients and comparison with a model of the respiratory system suggest that the changes of Rrs and Xrs are not explained totally by the observed increase in lung tissue resistance and decrease in lung compliance. The observed changes in Rrs and Xrs are not specific for restrictive lung disorders; similar changes are met also in moderately advanced obstructive diseases.  相似文献

Background

The joint recommendations of the German Societies of Anaesthesiology and Intensive Care Medicine, Surgery and Internal Medicine on preoperative evaluation of adult patients prior to elective, non-cardiac surgery published in November 2010 were the first practical and comprehensive guidelines for preoperative evaluation available to anesthetists in Germany.

Aim

This study was carried out to analyze the state of implementation of these guidelines into clinical practice as well as changes in strategies for assessing perioperative risk from the viewpoint of anesthesia personnel in Germany.

Material and methods

A 25-item questionnaire concerning general characteristics of workplaces, cognizance, reasonability and convenience of the joint recommendations was developed as an online survey. Furthermore, changes in strategies for preoperative evaluation were polled.

Results

A total of 1,840 anesthetists completed the questionnaire. The results showed that 84.2?% were acquainted with the joint recommendations, 57.3?% evaluated them as completely reasonable and 18.2?% as partly reasonable. A total of 71.4?% indicated that the joint recommendations were implemented completely or partly in their department strategies for preoperative evaluation. From the viewpoint of personnel, anamnesis and physical examination were performed more frequently by 25.7?% while routine diagnostic testing was ordered less frequently by 39.1?%. Advantages by implementing the joint recommendations (e.g. simplification for medical staff and patients, decrease of costs, reduction of radiological examinations) were seen by 45.5?%. Problems, such as increasing expenditure of time and personnel due to implementation were mentioned by 20.3?%.

Conclusion

The joint recommendations are well known and positively rated among anesthetists in Germany responding to the questionnaire reflecting an effective implementation process over the last 2 years. The anesthetists who completed the questionnaire stated that the use of the recommendations leads to a more reasonable approach in preoperative risk evaluation which contributes to an increase in patient safety and satisfaction.  相似文献
