AIM: To investigate the postprandial response of bone turnover markers in patients with Crohn’s disease (CD).METHODS: Fifty nine patients with CD aged 38 ± 14 years, and 45 healthy individuals matched for age and body mass index were included in the study. All participants underwent an oral glucose tolerance test (OGTT) after an overnight fast and serum levels of the bone resorption marker C-terminal crosslinking telopeptide of type I collagen (CTX-I) and the bone formation marker procollagen type I N propeptide were measured. Activity of the disease was assessed by calculation of the Crohn’s disease activity index (CDAI).RESULTS: Serum CTX-I was significantly higher in patients compared to controls (CTX-I: 453 ± 21 pg/mL vs 365 ± 25 pg/mL, P = 0.008), and values were significantly correlated with the activity of the disease (r = 0.435, P = 0.001). Results from OGTT-induced suppression of CTX-I showed two different trends. Patients with more active disease (assessed as CDAI > 150) had a more excessive suppression of CTX-I compared to controls (55% vs 43% P < 0.001), while patients on remission (assessed as CDAI < 150) demonstrated an attenuated CTX-I suppression (30% vs 43% P < 0.001). In line with this, CTX-I suppression after oral glucose load was significantly correlated with the activity of the disease (r = 0.913, P < 0.001).CONCLUSION: The physiological skeletal response of postprandial suppression of bone resorption is maintained in patients with CD and is strongly dependent to the activity of the disease. 相似文献

For many years, it has been evident that ambulatory blood pressure monitoring is superior to the measurement of office blood pressure as a predictor of target-organ involvement in patients with hypertension. Until recently, there were far fewer data on the relationship between 24 h ambulatory blood pressure and cardiovascular outcomes such as myocardial infarction, stroke, and cardiovascular death. In 1983, Perloff et al. published their seminal report on awake ambulatory blood pressure as a predictor of cardiovascular outcomes. During the 16 years that have passed since that publication, several additional prospective ambulatory blood pressure studies have been completed, in five different countries. The basis for all these investigations has been to assess the predictive value of ambulatory blood pressure as a determinant of either cardiovascular morbidity (myocardial infarction, cerebrovascular accidents, and vascular surgical procedures) or mortality. With the exception of the Systolic Hypertension in Europe (Syst-Eur) trial, all these studies have been uncontrolled for therapeutic interventions. Typically, the average follow-up period for each trial has been 3-9 years. All these studies have shown that ambulatory blood pressure is a much better predictor of cardiovascular events than the standard office or clinic pressure. In addition, hypertensive patients whose nocturnal (or sleep) blood pressure remains high (that is, those who have a 'non-dipper' circadian blood pressure profile) have a worse outcome than patients whose nocturnal blood pressure decline is at least 10%. These data all support the desirability of increased utilization of 24 h ambulatory blood pressure monitoring in clinical trials of antihypertensive drugs and in the management of hypertensive patients in clinical practice. 相似文献

Aim: To compare clinical characteristics and outcome of nonagenarian hip fracture patients with younger patients aged 65–89 years. Methods: This was a cohort follow‐up study of admissions for a hip fracture between 2005–2010 (mean follow up of 3.5 years) in two teaching hospitals in the Netherlands; 230 nonagenarians and 1014 patients aged 65–89 years were included. Clinical characteristics, adverse events, mobility and mortality were compared. Results: Nonagenarians were more likely to be female and anemic (both P < 0.001), and had more trochanteric fractures (P = 0.005). The number of American Society of Anesthesiologists III/VI classified patients did not differ between the two groups. During the hospital stay, adverse events were more frequently observed in nonagenarians compared with younger patients (P < 0.001). The length of stay was significantly longer in nonagenarians (P < 0.001), and the 90‐day readmission rate was similar. Absolute mortality was higher in nonagenarians (P < 0.001), excess mortality, however, was comparable. Before admission, 40.0% of the nonagenarians lived in their own home, and 40.9% had returned 3 months postfracture. The rate of returning to their own home was lower compared with younger patients (P < 0.001). Prefracture mobility was worse in nonagenarians compared with the younger group, but 3 months after discharge, the number of patients that regained prefracture mobility was comparable in both age groups. Conclusions: Nonagenarian hip fracture patients differ significantly from younger patients aged 65–89 years with respect to clinical characteristics and long‐term outcome. However, almost half of the nonagenarians returned to their own home and more than half regained their prefracture level of mobility. Given these findings, prevention strategies for hip fracture and adverse events during hospital stay that focus particularly on frail nonagenarians are highly recommended.

Brain metastasis occurs in 15-40% of cancer patients and is present in approximately 10-16% of patients with metastatic breast disease. However, little is known about prognostic factors enabling the early identification of breast cancer patients at risk of CNS metastases. Therapy for brain metastases should be based on several parameters, such as the assessment of prognostic variables, the extent of neurological and systemic disease, and its chemo-sensitivity to previously administered chemotherapy treatments. In view of the known close correlation between metastatic and primary tumor chemosensitivity, the type of chemotherapy chosen should depend more on the tumor histology than on the cerebral distribution of the single drug. More recent drugs with a high impact on the clinical outcome of metastatic breast cancer patients, such as taxanes or trastuzumab, play only a limited role in the treatment of brain metastases. 相似文献

Background
The impact of body composition on outcomes after surgery for colorectal liver metastases (CRLM) remains unclear. The aim of the present study was to determine the influence of sarcopenia, obesity and sarcopenic obesity on morbidity, disease-free (DFS) and overall survival (OS).Method
Between 2005 and 2012, all patients undergoing a partial liver resection for CRLM in the Maastricht University Medical Centre, and who underwent computed tomography (CT) imaging within 3 months before liver surgery, were included. Body composition was primarily based on pre-operative CT measurements. Sarcopenia was based on total muscle area at the level of the third lumbar vertebra and predefined body mass index (BMI)- and gender-specific cut-off values for sarcopenia were used. Body fat percentages were calculated and the top 40% for men and women were considered obese.Results
Of the 171 included patients undergoing liver surgery for CRLM, 80 (46.8%) patients were sarcopenic, 69 (40.4%) obese and 49 (28.7%) sarcopenic obese. The presence of sarcopenia, obesity or sarcopenic obesity did not affect the complication rates. However, readmission rates were significantly increased in patients with (sarcopenic) obesity (P < 0.05). Surprisingly, obesity seemed to prolong OS (P = 0.021) and was identified as an independent predictor [hazard ratio (HR):0.58 and P = 0.046] for better OS. Sarcopenia and sarcopenic obesity did not affect DFS or OS.Conclusion
Sarcopenia, obesity and sarcopenic obesity did not worsen DFS, OS and complication rates after a partial liver resection for CRLM. 相似文献8.
BACKGROUND: Patients with syncope frequently present with multitude of other symptoms but their significance in predicting morbidity or mortality has not been previously studied. OBJECTIVE: To determine if certain symptoms can be used to identify syncope patients at risk for cardiac arrhythmias, mortality, or recurrence of syncope. PATIENTS AND METHODS: From August 1987 to February 1991, we prospectively evaluated patients with syncope from outpatient, inpatient, and emergency department services of a university medical center. These patients were interviewed, charts were reviewed, and detailed information on 19 symptoms and comorbidities was obtained. A cause of syncope was assigned using standardized diagnostic criteria. All patients were followed up at 3-month intervals for at least 1 year for recurrence of syncope and mortality. Patients in whom the cause of syncope was determined by medical history and physical examination alone were not included in our analysis. RESULTS: History and physical examination led to the cause of syncope in 222 of 497 patients enrolled. In the remaining 275 patients, the absence of nausea and vomiting before syncope (odds ratio, 7.1) and electrocardiographic abnormalities (odds ratio, 23.5) were predictors of arrhythmic syncope. Underlying cardiac disease was the only predictor of 1-year mortality. No symptom remained as independent predictor for 1-year mortality or syncope recurrence. CONCLUSIONS: Symptoms, although important in assigning many noncardiac causes, are not useful in risk-stratifying patients whose cause of syncope cannot be identified by other history and physical examination. Triage decisions and management plans should be based on pre-existing cardiac disease or electrocardiographic abnormalities, which are important predictors of arrhythmic syncope and mortality. 相似文献

AIMS: Recent studies have suggested that patients with coronary disease suitable for angioplasty have an equally good outcome with medical therapy if clinically stable. Complex lesion morphology may predict acute events without intervention and stenosis severity influences the degree of collateralisation. This study was designed to assess the influence of these factors on clinical outcome. METHODS AND RESULTS: A retrospective review of patients suitable for angioplasty who were randomised to initial medical therapy as part of a multicentre study. Angiograms were reviewed for lesion characteristics, TIMI flow grade, and degree of collateralisation. Angiograms were available on 79 patients (13 female, 66 male). Mean age was 54.8 years (range 43-68) in the group crossing-over to revascularisation, and 58.4 (range 37-78) in the group who did not (P=ns). Seventeen patients crossed-over (two to CABG, 15 to PTCA) at 5.4 months (range 0-10) after initial angiography. Disease progression had occurred in 10/17 patients (58.8%), three of whom developed a new occlusion. Collateralisation was more likely in smokers, independent of lesion severity (P<0.05). Time to cross-over was not influenced by progression of disease. Crossing-over was not affected by age, diabetic status, cholesterol level, vessel involved, lesion severity, TIMI flow, lesion morphology, collateralisation, or the number of vessels diseased, but was more likely in females (P<0.05). CONCLUSION: This group of patients generally does well with medical therapy. Whilst the numbers are relatively small, there does not appear to be any reliable prospective marker, including the presence of spontaneous collateral channels on diagnostic angiography, to indicate which patients will fail medical therapy and require revascularisation. 相似文献

OBJECTIVE: Endoscopic mechanical lithotripsy is frequently used to overcome the difficulties of removing large bile duct stones endoscopically. The aim of this study was to identify predictors of endoscopic mechanical lithotripsy failure. MATERIAL AND METHODS: One hundred and thirty-four patients who underwent mechanical lithotripsy for difficult choledocholithiasis were evaluated retrospectively. Predictive factors of outcome and procedure-related complications were analyzed. The clinical outcomes of subsequent management were also evaluated in cases of unsuccessful endoscopic mechanical lithotripsy. RESULTS: Endoscopic mechanical lithotripsy was successful in 102 patients (76.1%). Stone impaction, size (>or=30 mm), and the stone size to bile duct diameter ratio (>1.0) were significant predictors of endoscopic mechanical lithotripsy failure, with estimated odds ratios of 17.83, 4.32 and 5.47, respectively. There was no difference in complication rates between the successful and failed mechanical lithotripsy groups. When mechanical lithotripsy failed, all patients were successfully treated using various modalities, including surgery, without mortality. CONCLUSIONS: An impacted stone, stone size (>or=30 mm) and stone size to bile duct diameter ratio (>1.0) were predictors of failure of endoscopic mechanical lithotripsy for a difficult bile duct stone. Alternative approaches should be considered in patients with predictors of unsuccessful endoscopic mechanical lithotripsy in order to avoid wasting time and resources. 相似文献

Do psychological factors predict symptom severity in patients with subjective food hypersensitivity?
《Scandinavian journal of gastroenterology》2013,48(7-8):835-843
AbstractObjective. We examined whether psychological factors such as general and gastrointestinal symptom-specific anxiety and depression could predict symptom severity in patients with unexplained, self-reported (subjective) food hypersensitivity. For the purpose, we translated and validated the Visceral Sensitivity Index (VSI). Material and methods. Seventy consecutive patients completed questionnaires for Hospital Anxiety and Depression Scale, VSI, Irritable Bowel Syndrome Symptom Questionnaire, and Subjective Health Complaints Inventory. Relationship between scores on psychological factors and scores on somatic symptoms were studied by multiple regression analyses. Results. Most patients reported non-gastrointestinal symptoms in addition to their irritable bowel syndrome complaints, but general and symptom-specific anxiety, and depression could not explain a significant amount of the variance in somatic complaints. Gastrointestinal symptom-specific anxiety was a significant predictor of gastrointestinal complaints (p = 0.02), and age was the sole significant predictor of non-gastrointestinal complaints (p = 0.01). Approximately 90% of the total variance in symptom severity remained unexplained by the psychological factors. The Norwegian version of the VSI had satisfactory validity (Cronbach alfa = 0.93). Symptom-specific and general anxiety were significantly correlated (r = 0.48, p ≤ 0.0001). Conclusions. Psychological factors were not major predictors of symptom severity in patients with subjective food hypersensitivity. The Norwegian version of VSI had satisfactory validity. 相似文献

As populations age, the number of osteoporotic fractures will increase. Bone mineral density (BMD) measurement remains the major way to diagnose osteoporosis and to indicate therapy. The FRAX tool, based on clinical risk factors, estimates the 10-year risk of hip and major osteoporotic fractures. The association of BMD and FRAX measurements has improved the identification of patients who are most at risk. However, some patients can still be overlooked and denied therapy. It is sound that adding the measure of bone turnover markers to the former risk factors and their follow-up during therapy could best address the efficacy of treatment of osteoporosis. Whether this behavior is cost-effective remains to be settled. 相似文献

Background and study aimsNon-invasive predictors of medium/large oesophageal varices (LOVs) could reduce the number of screening endoscopies. As portal hypertension is a consequence of liver fibrosis, serum fibrosis markers were evaluated together with other variables as possible non-invasive predictors of medium OV/LOV.Patients and methodsA total of 154 cirrhotic patients with splenomegaly and 30 healthy control subjects were recruited in a prospective study in two gastroenterology centres in Upper Egypt. Clinical parameters assessed included Child–Pugh class, liver size and ascites. Laboratory parameters included complete blood count, liver function tests, and aspartate aminotransferase (AST)/platelet ratio. Transforming growth factor-β1 (TGF-β1), alpha2 macroglobulin (A2M) and hyaluronic acid (HA) were assayed. Ultrasonographic examination was done for assessment of liver span, portal vein diameter and detection of minimal ascites. Oesophageal varices were diagnosed and graded by oesophagogastroduodenoscopy.ResultsFifty-four patients (35%) had no or small varices and 100 (65%) patients had medium OV/LOV by endoscopy. On multivariate analysis, the independent predictors of medium OV/LOV were the presence of ascites (β = 0.258, p = 0.047) and serum HA (β = 0.449, p = 0.009). The receiver operating characteristic curve for HA showed the area under the curve to be 0.916. The sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of HA at a cut-off value of 207 μg l?1 were 94%, 77.8%, 88.7%, 87.5% and 88.3%, respectively.ConclusionsThe presence of ascites and serum HA level higher than 207 μg l?1 can predict the presence of medium OV/LOV in cirrhotic patients. This would help physicians to identify patients who would most likely benefit from screening endoscopy and thus, reduce costs and discomfort from unnecessary endoscopic procedures. 相似文献

BACKGROUND: Osteoporosis is common in patients with COPD. Previously we have reported that loss of fat-free mass (FFM), measured by dual X-ray absorptiometry (DXA) is associated with loss of bone mineral density (BMD). In addition, in patients with a low body mass index (BMI) and a low FFM, all had evidence of bone thinning, 50% having osteopenia and 50% osteoporosis. We explored the utility of different anthropometric measures in detecting osteoporosis in a community-based COPD population. METHODS: Patients with confirmed COPD and not on long-term oral corticosteroids (n=58) performed spirometry. They underwent nutritional assessment by skinfold anthropometry, midarm circumference, calculation of both % ideal body weight (IBW) and BMI. All had DXA assessment of BMD. RESULTS: A total of 58 COPD patients had anthropometric measurements taken, with a mean age of 66.8 (SD 8.7) years, 31 (58%) were male, with a forced expiratory volume in 1s (FEV(1)) of 54.17 (20.18)% predicted. Osteoporosis was present at either the hip or lumbar region in 14 patients (24%). The useful anthropometric measurements identifying those with osteoporosis were both % IBW and BMI. The adjusted odds ratio for %IBW was 0.93 (95% confidence interval (CI) 0.87, 0.99), p=0.016 and for BMI: 0.79 (0.64-0.98), p=0.03. The receiver operating characteristics (ROC) score for both was 0.88, indicating a good fit. CONCLUSION: Osteoporosis is common, even in patients with mild airways obstruction. Nutritional assessment, incorporating a calculation of their BMI or %IBW may confer an additional benefit in detecting those at risk of osteoporosis and guide referral for BMD measurement. 相似文献
