Disease course in inflammatory bowel disease (IBD) is variable and difficult to predict. To optimize prognosis, it is of interest to identify phenotypic characteristics at disease onset and other ...prognostic factors that predict disease course. The aim of this study was to evaluate such factors in a population-based IBD group.
IBD patients diagnosed between 1 January 1991 and 1 January 2003 were included. A follow-up questionnaire was developed and medical records were reviewed. Patients were classified according to phenotype at diagnosis and risk factors were registered. Disease severity, cumulative medication use, and "surgical" and "nonsurgical" recurrence rates were calculated as outcome parameters.
In total, 476 Crohn's disease (CD), 630 ulcerative colitis (UC), and 81 indeterminate colitis (IC) patients were diagnosed. In CD (mean follow-up 7.6 years), 50% had undergone resective surgery. In UC (mean follow-up 7 years), colectomy rate was 8.3%. First year cumulative recurrence rates per 100 patient-years for CD, UC, and IC were 53, 44, and 42%, respectively. In CD, small bowel localization and stricturing disease were negative prognostic factors for surgery, as was young age. Overall recurrence rate was increased by young age and current smoking. In UC, extensive colitis increased surgical risk. In UC, older age at diagnosis initially increased recurrence risk but was subsequently protective.
This population-based IBD study showed high recurrence rates in the first year. In CD, small bowel localization, stricturing disease, and young age were predictive for disease recurrence. In UC, extensive colitis and older age at diagnosis were negative prognostic predictors.
The importance of fatigue in chronic disease has been increasingly recognized; however, little is known about fatigue in inflammatory bowel disease (IBD). The aim of the present study was to ...investigate the prevalence and severity of fatigue and the impact on health-related quality of life (HRQoL) in patients included in a population-based IBD cohort in the Netherlands.
IBD patients, diagnosed between January 1st, 1991, and January 1st, 2003, were followed up for a median of 7.1 years. They completed a questionnaire, which included a disease activity score, the Multidimensional Fatigue Inventory (MFI-20), the Inflammatory Bowel Disease Questionnaire (IBDQ), and the Short Form health survey (SF-36). Hemoglobin levels were recorded.
Data were available in 304 Crohn's disease (CD), 368 ulcerative colitis (UC), and 35 indeterminate colitis (IC) patients. During quiescent disease, the prevalence of fatigue was nearly 40%. MFI-20 and HRQoL scores were significantly worse in IBD patients having active disease. In a multivariate analysis, disease activity was positively related with the level of fatigue in both CD and UC. In UC, anemia influenced the general fatigue score independently of disease activity. Disease activity as well as fatigue were independently associated with an impaired IBDQ.
In IBD, even in remission, fatigue is an important feature. Both in CD and in UC, fatigue determined HRQoL independently of disease activity or anemia. This implies that in IBD patients physicians need to be aware of fatigue in order to better understand its impact and to improve the HRQoL.
Nonadherence to antihypertensive drugs (AHDs) is a major contributor to pseudo-resistant hypertension. The primary objective of this study was to determine the prevalence of nonadherence to AHDs ...among patients visiting the nephrology and vascular outpatient clinics.
Patients were eligible to participate in this prospective observational study if they used at least two AHDs that could be measured with a validated UHPLC-MS/MS method and had an office blood pressure at least 140 and/or at least 90 mmHg. For resistant hypertension, included patients had to use at least three AHDs including a diuretic or four AHDs. Adherence was assessed by measuring drug concentrations in blood. The complete absence of drug in blood was defined as nonadherence. A posthoc analysis was performed to determine the influence of a having a kidney transplant on the adherence rates.
One hundred and forty-two patients were included of whom 66 patients fulfilled the definition of resistant hypertension. The overall adherence rate to AHDs was 78.2% ( n = 111 patients), with the highest adherence rate for irbesartan (100%, n = 9) and lowest adherence rate for bumetanide ( n = 69%, n = 13). In further analysis, only kidney transplantation could be identified as an important factor for adherence (adjusted odds ratio = 3.35; 95% confidence interval 1.23-9.09). A posthoc analysis showed that patients with a kidney transplant were more likely to be adherent to AHDs (non-KT cohort 64.0% vs. KT-cohort 85.7%, χ 2 (2) = 10.34, P = 0.006).
The adherence rate to AHDs in hypertensive patients was high (78.2%) and even higher after a kidney transplant (85.7%). Furthermore, patients after kidney transplant had a lower risk of being nonadherent to AHDs.
The present study investigated the influences of a 2-wk training program on intramyocellular lipid (IMCL) content, IMCL decrease during exercise, fat oxidation, and insulin sensitivity.
Nine ...untrained men (age, 23.3 ± 3.2 yr; body mass index, 22.6 ± 2.6 kg/m2; maximal power output, 3.8 ± 0.6 W/kg body weight) trained for 2 wk. Before and after training, subjects cycled for 3 h while substrate oxidation was measured. IMCL content in the vastus lateralis muscle was determined before and after cycling by proton magnetic resonance spectroscopy. Before and after training, insulin sensitivity was assessed by an insulin tolerance test.
The training period resulted in a significant increase in IMCL content by 42 ± 14%. IMCL content decreased significantly during cycling. However, 2 wk of training were not sufficient to achieve increases in fat oxidation and/or use of IMCL during exercise. All markers used to test insulin sensitivity point toward improved insulin sensitivity, albeit not significant. We conclude that the increase in IMCL content is a very early response to training, preceding significant changes in insulin sensitivity. The results suggest that the presence of triglycerides alone does not necessarily have detrimental effects on insulin sensitivity. We confirm earlier reports that IMCL contributes to the energy used during prolonged submaximal exercise.
Thoracic aortic aneurysms (TAAs) are permanent pathological dilatations of the thoracic aorta, which can lead to life-threatening complications, such as aortic dissection and rupture. TAAs frequently ...occur in a syndromic form in individuals with an underlying genetic predisposition, such as Marfan syndrome (MFS) and Loeys-Dietz syndrome (LDS). Increasing evidence supports an important role for transforming growth factor-β (TGF-β) and the renin-angiotensin system (RAS) in TAA pathology. Eventually, most patients with syndromic TAAs require surgical intervention, as the ability of present medical treatment to attenuate aneurysm growth is limited. Therefore, more effective medical treatment options are urgently needed. Numerous clinical trials investigated the therapeutic potential of angiotensin receptor blockers (ARBs) and β-blockers in patients suffering from syndromic TAAs. This review highlights the contribution of TGF-β signaling, RAS, and impaired mechanosensing abilities of aortic VSMCs in TAA formation. Furthermore, it critically discusses the most recent clinical evidence regarding the possible therapeutic benefit of ARBs and β-blockers in syndromic TAA patients and provides future research perspectives and therapeutic implications.
Abstract Background Ambiguity exists whether gender affects outcome in patients undergoing percutaneous coronary intervention (PCI). Methods To evaluate the relationship between gender and outcome in ...a large cohort of PCI patients, 11,931 consecutive patients who underwent PCI for various indications during 2000–2009 were studied using survival analyses and Cox regression models. Results Most patients (n = 8588; 72%) were men. Women were older and more often had a history of hypertension and diabetes mellitus. Men smoked more frequently, had a more extensive cardiovascular history (previous MI, PCI and CABG), a higher prevalence of renal impairment and multi-vessel disease. In STEMI patients, women had higher 31-day mortality rates than men (11.6% vs. 6.5%, respectively, p < 0.001). This difference remained after adjustment for confounders (aHR at 30-days 1.54 and 95% CI 1.22–1.96). Likewise, higher mortality was observed at 1-year (15.1% vs. 9.3%) and 4-year follow-up (21.6% vs. 15.0%, aHR 1.30 and 95% CI 1.10–1.53). There were no differences in mortality between women and men in NSTE-ACS (aHR at 4-years 1.05 and 95% CI 0.85–1.28) or stable angina (HR at 4-years 0.85 and 95% CI 0.68–1.08). Conclusion Women undergoing PCI for STEMI had higher mortality than men. The excess mortality in women appeared in the first month after PCI and could only partially be explained by a difference in baseline characteristics. No gender differences in outcome in patients undergoing PCI for NSTE-ACS and stable angina were observed.

Abstract
Introduction
The optimal treatment plan for patients with cancer is discussed in multidisciplinary team meetings (MDTMs). Effective meetings require all participants to have collaboration ...and communication competences. Participating residents (defined as qualified doctors in training to become a specialist) are expected to develop these competences by observing their supervisors. However, the current generation of medical specialists is not trained to work in multidisciplinary teams; currently, training mainly focuses on medical competences. This study aims to identify barriers and facilitators among residents with respect to learning how to participate competently in MDTMs, and to identify additional training needs regarding their future role in MDTMs, as perceived by residents and specialists.
Methods
Semi-structured interviews were conducted with Dutch residents and medical specialists participating in oncological MDTMs. Purposive sampling was used to maximise variation in participants’ demographic and professional characteristics (e.g. sex, specialty, training duration, type and location of affiliated hospital). Interview data were systematically analysed according to the principles of thematic content analysis.
Results
Nineteen residents and 16 specialists were interviewed. Three themes emerged: 1) awareness of the educational function of MDTMs among specialists and residents; 2) characteristics of MDTMs (e.g. time constraints, MDTM regulations) and 3) team dynamics and behaviour. Learning to participate in MDTMs is facilitated by: specialists and residents acknowledging the educational function of MDTMs beyond their medical content, and supervisors fulfilling their teaching role and setting conditions that enable residents to take a participative role (e.g. being well prepared, sitting in the inner circle, having assigned responsibilities). Barriers to residents’ MDTM participation were insufficient guidance by their supervisors, time constraints, regulations hindering their active participation, a hierarchical structure of relations, unfamiliarity with the team and personal characteristics of residents (e.g. lack of confidence and shyness). Interviewees indicated a need for additional training (e.g. simulations) for residents, especially to enhance behavioural and communication skills.
Conclusion
Current practice with regard to preparing residents for their future role in MDTMs is hampered by a variety of factors. Most importantly, more awareness of the educational purposes of MDTMs among both residents and medical specialists would allow residents to participate in and learn from oncological MDTMs. Future studies should focus on collaboration competences.
This study examines the association between somatic co-morbidity and both general and disease-specific health-related quality of life (HRQoL) in patients with asthma and chronic obstructive pulmonary ...disease (COPD). A cross-sectional analysis was done among 161 COPD patients and 395 asthma patients, aged 40–75 years, recruited from general practice. In the total study population, 47% had no, 32% had one, and 21% had two or more somatic co-morbid conditions, with no significant differences between asthma and COPD patients. Co-morbidity appeared to be associated with poor disease-specific HRQoL in asthma odds ratio (OR) = 2.08 (1.37–3.18) and with poor general HRQoL in asthma OR = 2.96 (1.93–4.53) and COPD 1.81 (0.91–3.60) patients. Poorest HRQoL was found in patients with more than one co-morbid condition. Cardiac disease and hypertension were associated with poor disease-specific HRQoL in asthma. Of all co-morbid conditions, musculoskeletal disorders were most strongly associated with poor general HRQoL. Cardiac disease was found to be associated with general and disease-specific HRQoL in asthma but not in COPD. In studies on patients with asthma or COPD aged 40–75 years, co-morbidity should be treated as a determinant of HRQoL.
