In a series of 205 node-negative breast cancers (NNBC), we determined staining by the novel antibody Ki-S1, a marker of tumor cell proliferation, in order to test its association with other prognostic variables and its prognostic significance. Ki-S1 was determined in routinely formalin-fixed paraffin-embedded tumor samples. Ki-S1 gave a nuclear staining in the majority of the carcinomas (188 of 205), with percentages of reacting nuclei ranging from 2% to 90% (median value of 7%). In 107 tumors frozen sections were available to also assess the Ki-67 antibody. Among these, 94 had a nuclear staining of cancer cells ranging from 5% to 80% (median value of 7%). In 46 tumors we also determined the MIB-1 antibody. The percentage of MIB-1 nuclear staining ranged from 1% to 50% (median value of 20%). There was no significant relationship between Ki-S1 and the other two cell kinetic markers. Ki-S1 labeling was significantly associated only with tumor size (p = 0.03).With a median follow-up of 6 years, Ki-S1 had no significant prognostic value for either relapse-free survival (RFS) or overall survival (OS)(Ki-S1 as continuous logarithmic variable; p = 0.86 and p = 0.23, respectively). For RFS the following variables had a significant prognostic value: Ki-67 ( 10% vs > 10%; p = 0.037); progesterone receptor (PgR) expression (– vs +/++; p = 0.041); tumor size (pT1 vs pT2–3; p = 0.042) and grading (GI vs GII–III; p = 0.047). For OS, tumor size (p = 0.0044), age (continuous variable; p = 0.0060), and Ki-67 (p = 0.043) were significantly prognostic.In multivariate analysis (final model), only tumor size retained a significant and independent prognostic value for RFS (p = 0.0042). For OS, both tumor size (p = 0.0029) and age ( 55 years vs > 55 years; p = 0.041) retained significance in the multivariate model.In conclusion, Ki-S1 does not seem to have prognostic relevance in this series of NNBC. Possible hypotheses to explain this observation are discussed. 相似文献

The 24 h periodic pattern of blood pressure was studied in 44 patients with diabetes mellitus (14 type 1, 30 type 2; mean duration of disease 6.5 ± 1.8 years) in good metabolic control but with abnormal cardiovascular reflex responses; of these 21 were normotensive and 23 hypertensive. All had abnormal responses to at least two out of four tests: deep breathing, lying to standing, Valsalva manoeuvre and postural hypotension. Two sex- and agematched groups, consisting of 20 normotensive and 20 hypertensive diabetic patients without dysautonomia, were studied as controls. Each patient underwent ambulatory blood pressure monitoring for at least 24 h, using an auscultatory automatic device. Data were analysed using the sum of three periodic functions (Fourier partial sum). In the diabetic normotensive groups, the absolute blood pressure fell to its night-time minimum more rapidly, and increased to its morning maximum more slowly, in those with abnormal cardiovascular reflexes than in the controls (nightly blood pressure decrease –5.8/–4.7 vs. –3.8/–4.0 mmHg/h; increase 4.7/3.6 vs. 5.9/6.1 mmHg/h). The same behaviour was found in both hypertensive groups but the amplitude of the differences was more marked (blood pressure nocturnal decrease –7.7/–7.1 vs. –4.3/–3.9 mmHg/h; increase 3.2/2.1 vs. 5.8/4.3 mmHg/h). This analysis of 24 h ambulatory blood pressure data may be of value in diagnosis and evaluation of autonomic deficits. 相似文献

Frequency of anxiety disorders in psychiatric outpatients with major depressive disorder 总被引:3,自引:0,他引:3
OBJECTIVE: The authors determined the frequency of anxiety disorders in a large group of depressed outpatients seeking treatment. METHOD: The Structured Clinical Interview for DSM-IV was administered to 373 depressed outpatients. RESULTS: More than one-half of the patients met the full criteria for a current anxiety disorder, and more than one-half of the patients with an anxiety disorder had more than one. When partial remissions and anxiety disorder diagnoses classified as "not otherwise specified" were included, two-thirds of the patients had a current anxiety disorder and three-quarters had a lifetime history of an anxiety disorder. CONCLUSIONS: The majority of patients with a principal diagnosis of unipolar major depressive disorder have a comorbid anxiety disorder. Because antidepressant medications have differential efficacies for anxiety disorders, knowledge of the presence of a comorbid anxiety disorder in a depressed patient may have treatment implications. 相似文献

Deletion 22q11.2 is a chromosomal abnormality detected in young patients with clinical manifestations of the DiGeorge/velocardiofacial syndrome. Conotruncal heart defects are also associated with del22q11.2. An association of these cardiac malformations with neoplasias has been observed. Our series includes two cases of malignancies, a hepatoblastoma and a renal-cell carcinoma, arising in children with complex cardiac malformations. The aim of the study was to determine if the deletion at 22q11.2 was present and could be responsible for both pathological processes. Del22q11.2 was identified in both cases. Comparative genomic hybridization revealed terminal gains on chromosomes 1q and Xq and terminal loss on 1p in the hepatoblastoma, and gains in 1p, 12q, 16p, 20q, 22q, and whole chromosome 19 and loss of Xq in the renal-cell carcinoma. Our results confirm a common genetic basis for cardiac malformations, and del22q11.2 presents a risk factor for the development of pediatric tumours. 相似文献

Objective
To identify the factors associated with recovering autonomy in activities of daily living (ADL) in patients who have had a hip fracture.Design
A prospective cohort study.Setting
The orthopedic and orthogeriatric departments of 2 regional hospitals.Participants
Patients (N=742) aged ≥65 years with a diagnosis of fragility hip fracture.Main Outcome Measures
The level of autonomy at 4 months was assessed using the ADL scale.Results
The median score on the ADL scale at 4 months was 3 (interquartile range, 5). Half of the population was unable to recover their prefracture autonomy levels. The following were found to be risk factors: increasing age (B=.02, P<.001); an elevated number of comorbidities (B=.044, P=.005); a lower level of prefracture autonomy (B=.087, P<.001); more frequent use of an antidecubitus mattress (B=.211, P<.001); an increased number of days with disorientation (B=.002, P=.012); failure to recover deambulation (B=.199, P<.001); an increased number of days with diapers (B=.003, P<.001), with a urinary catheter (B=.03, P<.001), and with bed rails (B=.001, P=.014); and a nonintensive care pathway (B=.199, P=.014).Conclusions
Recovery of deambulation, treatment of disorientation and management of incontinence are modifiable factors significantly associated with the functional recovery of autonomy. 相似文献19.
