The fecal markers Lf, Cal, and PMN-e are able to differentiate active IBD from inactive IBD as well as from IBS. None of these three stool markers is consistently superior in its ability to reflect endoscopic inflammation, but all three are superior to CRP in their diagnostic accuracy. A combination of the stool markers with the CRP and a disease-specific activity index in a categorical comprehensive activity index can increase the diagnostic accuracy with reference to the endoscopic inflammation in UC.

Calorie restriction or changes in dietary composition can enhance healthy aging, but the inability of most subjects to adhere to chronic and extreme diets, as well as potentially adverse effects, limits their application. We randomized 100 generally healthy participants from the United States into two study arms and tested the effects of a fasting-mimicking diet (FMD)-low in calories, sugars, and protein but high in unsaturated fats-on markers/risk factors associated with aging and age-related diseases. We compared subjects who followed 3 months of an unrestricted diet to subjects who consumed the FMD for 5 consecutive days per month for 3 months. Three FMD cycles reduced body weight, trunk, and total body fat; lowered blood pressure; and decreased insulin-like growth factor 1 (IGF-1). No serious adverse effects were reported. After 3 months, control diet subjects were crossed over to the FMD program, resulting in a total of 71 subjects completing three FMD cycles. A post hoc analysis of subjects from both FMD arms showed that body mass index, blood pressure, fasting glucose, IGF-1, triglycerides, total and low-density lipoprotein cholesterol, and C-reactive protein were more beneficially affected in participants at risk for disease than in subjects who were not at risk. Thus, cycles of a 5-day FMD are safe, feasible, and effective in reducing markers/risk factors for aging and age-related diseases. Larger studies in patients with diagnosed diseases or selected on the basis of risk factors are warranted to confirm the effect of the FMD on disease prevention and treatment.

Summary Dietary interventions have not been effective in the treatment of multiple sclerosis (MS). Here we show that periodic 3 day cycles of a fasting mimicking diet (FMD) are effective in ameliorating demyelination and symptoms in a murine experimental autoimmune encephalomyelitis (EAE) model. The FMD reduced clinical severity in all mice, and completely reversed symptoms in 20% of the animals. These improvements were associated with increased corticosterone levels and Treg cell number, reduced levels of pro-inflammatory cytokines, TH1 and TH17 cells, and antigen presenting cells (APCs). Moreover, the FMD promoted oligodendrocyte precursor cell regeneration and remyelination in axons in response to both EAE and cuprizone MS models, supporting its effects on both suppression of autoimmunity and remyelination. We also report preliminary data suggesting that a FMD or a chronic ketogenic diet are safe, feasible and potentially effective in the treatment of relapsing remitting multiple sclerosis (RRMS) patients (NCT01538355).

Objective-To determine the distribution and importance of various factors, especially the preventable ones, that contribute to cardiac decompensation and subsequent hospital admission for heart failure. Methods-During a one year period patients were prospectively recruited and evaluated during their hospital stay by means of a structured personal interview by trained medical staV and through clinical examination and laboratory investigation. Setting-The cardiological department at a teaching aYliated general community hospital in Berlin, Germany. Patients-Consecutive sample of 179 patients admitted to hospital with acute decompensation of pre-existing heart failure. Main outcome measures-Proportional distribution of causative factors leading to hospital admission for heart failure; relative importance of preventable factors; details of patient compliance with diet and medication, and knowledge about medication. Results-Mean (SD) age was 75.4 (9.9) years. Potential causative factors for decompensated heart failure were identified in 85.5% of patients. Lack of adherence to the medical regimen was the most commonly identified factor and was regarded as the cause of the cardiac decompensation in 41.9% of cases. Non-compliance with drugs was found in 23.5% of patients. Other factors related to hospital admission were coronary ischaemia (13.4%), cardiac arrhythmias (6.1%), uncontrolled hypertension (5.6%), and inadequate preadmission treatment (12.3%). In all, 54.2% of admissions could be regarded as preventable. Conclusions-Many hospital admissions for decompensation of chronic heart failure in patients at a district hospital in Berlin are preventable. Measures are necessary to improve this situation and evaluation of programmes that include patient education, patient follow up, and physician training is needed. (Heart 1998;80:437-441)
