There is debate about the value of assessing levels C-reactive protein (CRP) and other biomarkers inflammation for prediction first cardiovascular events.We analyzed data from 52 prospective studies that included 246,669 participants without a history disease to investigate adding CRP or fibrinogen conventional risk factors risk. We calculated measures discrimination reclassification during follow-up modeled clinical implications initiation statin therapy after assessment fibrinogen.The...

Disease surveillance and population surveys of risk characteristics in a northeast rural community Japan (1965 census population, 7,030) are combined an attempt to relate morbidity factor trends for coronary heart disease stroke during the last 2 decades. Between 1964 1983, incidence (i.e., myocardial infarction, angina pectoris, sudden death) did not change significantly among men women ages 40-69, was lower than that stroke. The all declined about 60% both women, with significant decrease...

Abstract To examine the relation of triglycerides with coronary heart disease among populations low mean total cholesterol, authors conducted a 15.5-year prospective study ending in 1997 11,068 Japanese aged 40–69 years (4,452 men and 6,616 women cholesterol = 4.73 mmol/liter 5.03 mmol/liter, respectively), initially free or stroke. There were 236 events comprising 133 myocardial infarctions, 68 angina pectoris events, 44 sudden cardiac deaths. The incidence was greater dose-response manner...

Evidence linking the gut-brain axis to Alzheimer's disease (AD) is accumulating, but characteristics of causally important microbes are poorly understood. We perform a fecal microbiome analysis in healthy subjects and those with mild cognitive impairment (MCI) AD. find that Faecalibacterium prausnitzii (F. prausnitzii) correlates scores decreases MCI group compared group. Two isolated strains from group, live Fp360 pasteurized Fp14, improve an AD mouse model. Whole-genome comparison reveals...

We recently established a clinic comprehensive assessments conditions such as frailty, sarcopenia, cognition, planned 3-year prospective observational study to identify progression aging-related statuses. To date, we recruited 323 patients who revealed symptoms...
