“…Habitual coffee consumption may raise the blood pressure [30]. Our results deviate from study conducted by Larsson et al [31] and Zhang et al [32] The Circadian pattern in onset of ischemic and hemorrhagic stroke showed a significant peak in morning (6 am-12 pm) and afternoon (12 pm-6 pm), respectively. The could be correlated to biological factors such as blood pressure (with physiological nocturnal decrease and morning increase), hemostatic balance (with increased platelet aggregability, increased level of hematocrit with hyperviscosity of blood in morning hypercoagulability, hypofibrinolysis) autonomic systemic activity (with activation of sympathetic nervous system after wake up movement with consequence on vascular tone, blood pressure, heart rate).…”

Objective: The objective of the work was to study the clinical profile of stroke in a tertiary care hospital.Methods: A prospective observational study on stroke was carried out for a period of 6-month (May 2015 to October 2015). A total of 241 inpatientsfrom Shri Preethi Hospital were incorporated in the study. The data were collected and evaluated by reviewing case files and patient interview.Result and Conclusion: Out of 241 patients, an incidence of ischemic stroke was found to be higher. The occurrence of stroke steeply rises with agewith male predominance. The burden of stroke tends to be more in rural, illiterate, and low socioeconomic status population. The study reveals riskfactors such as sedentary lifestyle, previous and family history of stroke, underlying disease like hypertension, diabetes. The circadian pattern in onsetshowed a significant peak in morning (6 am-12 pm) for Ischemic and afternoon (12 pm-6 pm) for hemorrhagic stroke. Topographic distribution ofcerebral infract and hemorrhage was found to be in parietal lobe and periventricular white matter, respectively. Mostly prescribed medication forischemic and hemorrhagic patients was antihypertensive and mannitol, respectively. The contraindication for thrombolytic therapy was found to below economic status and average delay in time of presentation to hospital. The study highlights the need for aggressive management of traditionalrisk factors, need for extensive work up in patient to find etiologies and need for more active interventions in community for the prevention of stroke.Keywords: Ischemic, Hemorrhagic, Circadian pattern, Antihypertensive.

“…An overview of systematic reviews is a relatively new approach to synthesizing a large body of literature in a particular area. Numerous systematic reviews of prospective studies regarding food groups associated with stroke have been published (6)(7)(8) . Systematic reviews of prospective studies are considered to provide a high level of evidence and represent a potentially powerful method to evaluate the long-term effects of food groups on stroke risk.…”

ObjectiveNumerous systematic reviews of prospective studies on the association of stroke risk with the consumption of various food groups have been published. A review of the evidence across the existing systematic reviews and meta-analyses of prospective studies was conducted to provide an overview of the range and validity of the reported associations of food groups with stroke risk.DesignThe PubMed, EMBASE and Cochrane Library databases were searched for articles published up to September 2015 to identify systematic reviews of prospective studies.ResultsA total of eighteen studies published from 2008 to 2015 were eligible for analysis. Overall, thirteen specific foods were studied for an association with stroke outcome, including nuts, legumes, fruits and vegetables, refined grains, whole grains, dairy products, eggs, chocolate, red and/or processed meat, fish, tea, sugar-sweetened beverages and coffee. Whereas a high consumption of nuts, fruits, vegetables, dairy foods, fish and tea, and moderate consumption of coffee and chocolate demonstrated a protective effect, a high consumption of red and/or processed meat was associated with increased stroke risk. Refined grain, sugar-sweetened beverage, legume, egg and whole grain intake showed no effect on stroke outcome.ConclusionsThe current overview provided a high level of evidence to support the beneficial effect of specific foods on stroke outcome. Clinicians and policy makers could inform clinical practice and policy based on this overview.

“…Consumption has also recently been associated with increased all-cause mortality [7]. In contrast, recent epidemiological studies have suggested that regular coffee consumption could decrease the risk of type II diabetes, Parkinsonism, Alzheimer's disease, liver cancer, and even the risk of stroke [2], [8]–[10].…”

New Biomarkers of Coffee Consumption Identified by the Non-Targeted Metabolomic Profiling of Cohort Study Subjects

et al. 2014

Coffee contains various bioactives implicated with human health and disease risk. To accurately assess the effects of overall consumption upon health and disease, individual intake must be measured in large epidemiological studies. Metabolomics has emerged as a powerful approach to discover biomarkers of intake for a large range of foods. Here we report the profiling of the urinary metabolome of cohort study subjects to search for new biomarkers of coffee intake. Using repeated 24-hour dietary records and a food frequency questionnaire, 20 high coffee consumers (183–540 mL/d) and 19 low consumers were selected from the French SU.VI.MAX2 cohort. Morning spot urine samples from each subject were profiled by high-resolution mass spectrometry. Partial least-square discriminant analysis of multidimensional liquid chromatography-mass spectrometry data clearly distinguished high consumers from low via 132 significant (p-value<0.05) discriminating features. Ion clusters whose intensities were most elevated in the high consumers were annotated using online and in-house databases and their identities checked using commercial standards and MS-MS fragmentation. The best discriminants, and thus potential markers of coffee consumption, were the glucuronide of the diterpenoid atractyligenin, the diketopiperazine cyclo(isoleucyl-prolyl), and the alkaloid trigonelline. Some caffeine metabolites, such as 1-methylxanthine, were also among the discriminants, however caffeine may be consumed from other sources and its metabolism is subject to inter-individual variation. Receiver operating characteristics curve analysis showed that the biomarkers identified could be used effectively in combination for increased sensitivity and specificity. Once validated in other cohorts or intervention studies, these specific single or combined biomarkers will become a valuable alternative to assessment of coffee intake by dietary survey and finally lead to a better understanding of the health implications of coffee consumption.
