AIMS: The aim of this study is to compare PUMA curves with different pathologic conditions causing bladder dysfunction in 158 men and 83 women. METHODS: PUMA results in terms of bladder outlet obstruction and detrusor contractility were compared in 92 men with benign prostatic hypertrophy (BPH) and p(ves) congruent with p(det) (i.e., p(abd) congruent with 0) with the results of the urodynamics operator's opinion, the provisional International Continence Society method, Abrams and Griffith's diagram, urethral resistence factor (URA), Sch?fer's diagram, and Watt factor. PUMA curves correlated reliably with different pathologic conditions such as obstructive BPH, orthotopic bladder, cystocele, the neurological bladder, and bladder diverticulum. Statistical analysis indicated excellent agreement between PUMA and URA; agreement with other methods was good in cases of obstruction and nonobstruction. In doubtful cases, as diagnosed by standard methods, PUMA agreed only with the Abrams and Griffith's diagram. PUMA and Wmax were in good agreement on detrusor con traction force. Agreement between PUMA and Sch?fer's diagram was excellent for patients with detrusor hypercontractility and good for patients with detrusor hypocontractility and normocontractility. PUMA is the only method applicable to women. It is easy to perform. When integrated with other diagnostic tests, it provides realistic data for diagnosis, medical or surgical therapy, and outcome. 相似文献

1. 1. The P3 component of a visual event related potential (ERP) was studied for five consecutive weeks in six women with normal menstrual cycles. Serum concentrations of luteinizing hormone (LH), estradiol (E2) and progesterone were studied during the same period.
2. 2. Increases in P3 amplitude, although nonsignificant, were noted in the week preceding onset of menses.
3. 3. No significant changes in reaction times to target/nontarget stimuli were noted over the same time period.

Summary The force-velocity curve (FVC) of arm flexion was established in 123 untrained males and 110 untrained females aged from 15 to 36 years, and 48 arm-trained athletes competing in different sport disciplines. The FVC was described by Hill's equation and defined by the parameters: maximal static moment (M0), maximal angular velocity (0), maximal power (P0) and the concavity of the FVC (H). Within the given age range the level of the curve parameters of both untrained men and women was independent of age.On average, H was the same in all three groups. As compared to M0 of the untrained males, M0 of the athletes was 33% higher and M0 of the females was 38% lower; with regard to P0 these differences were +30% and –43% respectively. 0 was the same for trained and untrained males, wherease 0 of the women was 10% lower than 0 of the men. 相似文献

Data from a multicenter case-control study on breast cancer conducted in Italy have been used to analyze the relationship of olive oil and other dietary fats to breast cancer risk. Cases were 2,564 women hospitalized with histologically confirmed, incident breast cancer. Controls were 2,588 women admitted to the same network of hospitals for acute, non-neoplastic, non-hormone related, on-digestive tract disorders. Cases and controls were interviewed between 1991 and 1994 using a validated food-frequency questionnaire. The data were modelled through multiple logistic regression controlling for demographic and reproductive breast-cancer risk factors, energy intake and, mutually, for types of dietary fat. For olive oil, compared with the lowest quintile, the odds ratios (OR) were 1.05, 0.99, 0.93, and 0.87 for increasing quintiles of intake; in a model postulating linear logit increase, the OR per unit (30g) was 0.89 (95 percent confidence interval [CI]=0.81–0.99, P=0.03). Among other oils or fats considered, the OR for the highest level of intake was 0.72 (CI=0.6–0.9) for a group of specific seed oils (including safflower, maize, peanut, and soya) compared with nonusers. The ORs for the highest cf lowest level of intake were 0.80 for mixed or unspecified seed oils, 0.95 for butter, and 0.96 for margarine. The study, based on a large dataset from various Italian regions, shows an inverse relationship of breast cancer risk with intake of olive oil and other vegetable oils, but not with butter or margarine. 相似文献

[Purpose] This study aimed to investigate the prevalence of frailty among community-dwelling elderly females, and to examine its relation to motor function and the main risk factors of frailty. [Participants and Methods] The participants were 67 community-dwelling elderly females, aged 76.2 ± 7.7 years. We performed measurements of physical parameters, motor functions (such as grip strength), timed up and go test (TUG), walking speed, and frailty (measured using the Kihon Checklist [KCL]). [Results] KCL scores were 31.3%, 31.3%, and 37.3% in the frailty, pre-frailty, and robust groups, respectively. The frailty group was older than the pre-frailty and robust groups. Additionally, the different groups showed significant differences in grip strength, TUG, and walking speed. The highest median KCL score was for depression, followed by physical function. As a results, frailty was evident even among health-conscious elderly people. [Conclusion] It is essential to identify frailty at an early stage and identify its preventive factors, in order to extend the healthy life expectancy of the local population. 相似文献

Oral microbiota has been implicated in pathogenesis of recurrent aphthous stomatitis (RAS), which is a common mucosal disorder with unclear etiology. This study has explored the association between oral microbiota disorder and RAS in high-risk young female population.Forty-five young females were enrolled, including 24 RAS patients and 21 healthy individuals. Oral microbiome was analyzed by Illumina Miseq sequencing.Oral microbiota associated with RAS was characterized by the lower alpha-diversity indices (Chao1 and ACE). Several infectious pathogens increased in RAS, such as genera Actinobacillus, Haemophilus, Prevotella and Vibrio. The PICRUSt analysis indicated that the oral microbiota might be related with the up-regulation of genes involving infectious and neurodegenerative diseases, environmental adaptation, the down-regulation of genes involving basal metabolism, such as carbohydrate, energy, and amino acid metabolism.This study indicated that oral microbiota may play a significant role in RAS development. 相似文献

The objective of this study was to determine the serum concentration of angiogenic factors (vascular endothelial growth factor, VEGF; transforming growth factor beta, TGF-β1; hepatic growth factor, HGF; basic fibroblast growth factor, bFGF; tumor necrosis factor alpha, TNF-α; soluble vascular endothelial growth factor receptor 1, sVEGF-R1; soluble vascular endothelial growth factor receptor 2, sVEGF-R2), the relationships among them and to assess the relation of their levels with the applied therapy in 48 females with systemic lupus erythematosus (SLE; 37 long-term treated +11 newly diagnosed). The control group consisted of 24 healthy women. A statistically significant increase of sVEGF-R2 and significant decrease of sVEGF-R1 were observed in the subgroup of newly diagnosed SLE patients as compared to the control subjects. No significant differences were found between serum angiogenic factors in the long-term treated subgroup and the control, the long-term treated subgroup and the newly diagnosed SLE patients after a 3-month treatment, and the subgroup of newly diagnosed SLE patients before therapy and after a 3-month treatment. The significant decrease in the serum of sVEGF-R2 was revealed in the subgroup treated for a long-time as compared to the subgroup of newly diagnosed untreated SLE patients. The analysis of relationships between serum concentration of sVEGF-R1 and other cytokines levels revealed positive correlation with concentration of VEGF and TNF-α in the total group of patients. In the newly diagnosed untreated subgroup, a strong positive correlation between concentration of sVEGF-R1 and bFGF was observed. Furthermore, a moderate positive correlation between concentration of sVEGF-R1 and the level of VEGF was revealed in the long-term treated patients. The association between sVEGF-R2 and HGF was also noted in this subgroup. The obtained data suggest the necessity of further investigations to determine the importance of angiogenic factors in pathogenesis and therapy of SLE. 相似文献
