To analyze the inter- and intra-individual variability of acute insulin response to intravenous glucose (AIRG), 41 healthy volunteers underwent an intravenous glucose tolerance test (IVGTT) and 29 of them a second IVGTT 1 to 9 months later. Basal glycemic, insulin (IRI), and C-peptide values were similar for both IVGTTs. Different indices were used to estimate AIRG. A great inter-individual variability of AIRG (CV around 60%) was detected. AIRGs were not statistically different between the two IVGTTs, and the within-subject variation was fair at the group level (CVs approximately 30%). However, individual coefficients of variation ranged from 2 to 60% between the two tests. Moreover, subjects considered as "low" responders during test 1, returned to "normal" values during test 2. Conversely, other subjects dropped to a "low" response in IVGTT 2. Insulin peak (IRI max) occurred between 1 and 3 minutes after glucose infusion in 85% of the control population, but time points of IRI max were different for 45% of the population between the two IVGTTs. These results suggest that AIRG during IVGTTs are reproducible at the group level, but that AIRG has to be interpreted with caution in individual early detection of pre-insulin-dependent diabetes mellitus because inter- and intra-individual variability could be high even for some normal subjects. 相似文献

The purpose of this study was to analyze which 24‐hour ambulatory blood pressure measurement (ABPM) parameters should be used on masked hypertension (MH) and white‐coat hypertension (WCH) diagnoses in chronic kidney disease (CKD) patients. Non‐dialysis CKD patients underwent 24‐hour ABPM examination between 01/27/2004 and 02/16/2012. They were followed from the 24‐hour ABPM to January/2014 in an observational study. The WCH definitions tested were as follows: (a) office blood pressure (BP) ≥ 140/90 mm Hg and daytime ABPM BP ≤ 135/85 mm Hg (old criterion); and (b) office BP ≥ 140/90 mm Hg and 24‐hour ABPM BP ≤ 130/80 mm Hg, daytime ABPM BP ≤ 135/85 mm Hg, and nighttime ABPM BP ≤ 120/70 mm Hg (new criterion). The MH definitions tested were as follows: (a) office BP < 140/90 mm Hg and daytime ABPM BP > 135/85 mm Hg (old criterion); and (b) office BP < 140/90 mm Hg and 24‐hour ABPM BP > 130/80 mm Hg or daytime ABPM BP > 135/85 mm Hg or nighttime ABPM BP > 120/70 mm Hg (new criterion). The two definitions' predictive capacity was compared, regarding both WCH and MH. Cardiovascular mortality was the primary and all‐cause mortality was the secondary outcome. Cox regression was adjusted to the variables: glomerular filtration rate, age, diabetes mellitus, and active smoking. There were 367 patients studied. The old criterion (exclusive mean daytime ABPM BP) was the only to distinguish sustained hypertension from WCH (adjusted HR: 3.730; 95% CI: 1.068‐13.029; P = .039), regarding all‐cause mortality. Additionally, the old criterion was the only one to distinguish normotension and MH, regarding cardiovascular mortality (adjusted HR: 7.641; 95% CI: 1.277‐45.738; P = .026). Therefore, WCH and MH definitions based exclusively on daytime ABPM BP values (old criterion) were able to better distinguish mortality in this studied CKD cohort. 相似文献

To estimate the prevalence of urinary incontinence (UI) in elderly individuals of low income assisted by the primary health care system in S?o Paulo, Brazil. In this community-based, observational, cross-sectional study, participants assisted by the health family program in S?o Paulo, Brazil, were sampled and interviewed face to face by questionnaire. Participants (n=388) were selected from the collaborative program developed by the 10/66 Dementia Research Group, an International Network of investigators. Demographics, health history and a detailed assessment of UI and urinary symptoms were obtained. Prevalence of UI was calculated. Other variables included age, body mass index (BMI), duration of incontinence and characteristics of the symptoms. The association between UI and the variables was estimated using the Kruskal-Wallis test, Chi-squared test and Fisher test (depending on normality of the distribution and expected frequencies). Prevalence of UI was 38.4%. UI was more common in women than in men (50% vs. 18.3%, p<0.001). Diabetes, obesity and hypertension were associated with UI. Almost 36.2% of the cases were of mixed incontinence, 26.8% of urge incontinence and 24.2% of stress incontinence. Men were more likely to have urge-incontinence, while women were more likely to have mixed incontinence (p=0.001). UI is prevalent in the elderly of low income living in S?o Paulo and rates are higher than most previous studies. Chronic conditions such as hypertension, diabetes and obesity were associated with UI. 相似文献

Purpose
Malnutrition is a strong predictor of mortality in hemodialysis patients. Several scoring systems for evaluating nutritional status have been proposed. However, they rely on different sets of anthropometric and laboratory markers to make a diagnosis of malnutrition and assess its impact on prognosis. To validate them, nutritional scores should be compared with clinical outcomes. Thus, the purpose of this study was to assess malnutrition by three different nutrition scoring systems and determine which best predicts mortality in hemodialysis patients.Methods
This prospective study included 106 adult chronic hemodialysis patients. Their mean age was 56.3 ± 14.9 years and mean body mass index 24.8 (21.8–28.9); 52 % were men and they had been on dialysis for 24 (5–55) months. Nutritional status was classified according to the diagnostic systems proposed by Wolfson et al. (Am J Clin Nutr 39(4):547–555, 1984), International Society of Renal Nutrition and Metabolism (ISRNM) (Fouque et al. in Kidney Int 73(4):391–398, 2008), and Beberashvili et al. (Nephrol Dial Transplant 25(8):2662–2671, 2010). During about 2 years of follow-up, mortality was assessed by Kaplan–Meier curves, log-rank, and Cox’s models adjusted for diabetes, sex, C-reactive protein, time on dialysis, age, and fractional urea clearance.Results
Twenty-three deaths (21.5 %) occurred during the study period. According to the systems of Wolfson, Beberashvili, and the ISRNM, 54, 32, and 20 % of patients, respectively, had malnutrition. Both univariate and multivariate analyses showed that the ISRNM system was the only one that predicted poorer survival (fourfold higher death risk) in malnourished patients.Conclusions
The scoring system proposed by the ISRNM most accurately identifies patients at higher risk of death. 相似文献7.

Adrenal epithelioid angiosarcoma is an extremely rare tumor. Even if such tumors are very aggressive, a long survival may
occasionally be observed after an adrenal ectomy. A 70-year-old woman suffering from persistent right flank pain showed a
5-cm right adrenal mass plus a 2-cm liver mass at the radiologic workup, and both were suspected of being malignant. No adrenal
hypersecretion was demonstrated. During an explorative median laparotomy the right adrenal gland with the whole periadrenal
tissue and locoregional lymph nodes was removed. A histological examination revealed an adrenal angiosarcoma. The resection
margin was tumor-free with no lymph node infiltration. The liver mass turned out to be a cistobiliary adenoma. Since no distant
metastases were observed, no adjuvant chemotherapy was performed. After an 18-month follow-up the patient is still well with
no sign of a relapse. When this rare adrenal tumor is encountered and curative treatment is attempted initially extensive
surgical procedures are essential.

Ntera2/D1 cells had an A1 B8 Bw6 Cw7 DR3 DR52 major histocompatibility complex (MHC) genotype. Its neuronal derivative, hNT neurons, expressed A1 B8 Bw6 MHC class I molecules, but did not activate, and its hNT supernatant suppressed allogeneic mixed lymphocyte cultures (MLC) >98% (p<0.01), phytohemagglutinin (PHA)-activated T-cell proliferation >87% (p<0.01), even 48 h after stimulation, suppressed phorbol 12-myristate 13-acetate (PMA)/ionomycin-induced T-cell proliferation >99% (p<0.001), and reduced interleukin-2 (IL-2) production (p<0.01), while maintaining T cells in a quiescent G(0)/G(1) state without lowering their viability. This immunosuppressive activity was attributed to a 40-100-kDa anionic hNT protein with an isoelectric point of 4.8. 相似文献

Adrenalectomy represents the gold standard treatment for hyperfunctioning adrenal incidentaloma. In cases of silent adrenal masses, on the other hand, the surgical removal of an adrenocortical cancer entails the sacrifice of a large number of safe benign masses, and in most cases surgery is therefore unjustified. The aim of this paper was to clarify the surgical indications for adrenal incidentaloma by reviewing our experience in comparison with the main reference literature. Over the period from 1995 to 2001 we managed 40 cases of incidentaloma. US and CT abdominal scans, adrenal scintigraphy and biochemical tests were performed on an outpatient basis. Seven pre-Cushing syndromes were removed. Ten incidentalomas measured 4 cm or more in diameter: 5 of these were operated on and in 5 cases surgery was not feasible or was refused. Only one malignant mass was detected (an angiosarcoma). Four postoperative minimal complications (18.7%) were observed. The follow-up (median: 48 months) was uneventful. The surgical approach was traditional in 11 cases and laparoscopic in 1 case. Surgery should be considered mandatory in cases of hyperfunctioning adrenal masses in the presence of suspect radiological evidence, in cases of discordant CT and scintigraphy findings and when the maximum diameter is 4 cm or more. 相似文献
