cholecystokinin and Cardiovascular-Diseases

Sodium-bicarbonated mineral waters are reported to have beneficial digestive and hypocholesterolaemic properties. The aim of the study was to investigate the effects of consumption of a sodium-bicarbonated mineral water (BW) with or without a meal, compared to a low mineral content water as the control water (CW), on postprandial serum triacylglycerols (TAG), cholecystokinin (CCK) and gallbladder volume.. The study design was a four-way randomised controlled crossover trial. Healthy adult men and women (>18 and <40 years, TAG <2.82 mmol/L) consumed 0.5 L of CW + standard meal; 0.5 L of BW + standard meal; and 0.5 L of CW without meal or 0.5 L of BW without meal.. BW consumed without meal had no significant effect on the study parameters compared to CW. However, BW with meal induced a lower concentration of serum TAG at 30 min (p = 0.01) and 60 min (p = 0.03) postprandial times, lower CCK concentrations at 30 min (p = 0.002), and higher gallbladder volume at 30 min (p = 0.03), 60 min (p = 0.01) and 120 min (p = 0.04). Gallbladder ejection fraction was lower with the BW (p = 0.03), whilst area under the curve and peak contraction amplitude (lowest gallbladder volume) were higher (p = 0.01, p = 0.02, respectively) compared to the CW.. Consumption of BW with a meal induces lower levels of CCK and reduces gallbladder emptying and postprandial TAG levels. It is proposed that this sodium-bicarbonated mineral water could be used as part of the habitual diet by the general population in order to reduce cardiovascular risk.

Cholecystokinin (CCK) and gastrin are related gastrointestinal hormones with documented cardiovascular effects of exogenous administration. It is unknown whether measurement of endogenous CCK or gastrin in plasma contains information regarding cardiovascular mortality.. Mortality risk was evaluated using Cox proportional hazard regression and Kaplan-Meier analyses. Elderly patients in a primary care setting with symptoms of cardiac disease, i.e. shortness of breath, peripheral edema, and/or fatigue, were evaluated (n=470). Primary care patients were followed for 13years (from 1999); the 5-year all-cause and cardiovascular mortality was used as end point.. In univariate analysis, patients in the 4th CCK quartile had an increased risk of 5-year cardiovascular mortality (hazard ratio 3.9, 95% confidence interval: 2.1-7.0, p<0.0001). In multivariate analysis including established factors associated with cardiovascular mortality, CCK concentrations in the 4th quartile were still associated with increased 5-year cardiovascular mortality risk (HR 3.1, 95% C.I.: 1.7-5.7, p=0.0004), even when including 4th quartile NT-proBNP concentrations in the same model. We observed a marked difference between the genders, where CCK concentrations in the 4th quartile were associated with a higher 5-year cardiovascular mortality in female patients (HR 8.99, 95% C.I.: 3.49-102.82, p=0.0007) compared to men (1.47, 95% C.I.: 0.7-3.3, p=0.35). In contrast, no significant information was obtained from 4th quartile gastrin concentrations on 5-year cardiovascular mortality risk.. CCK in plasma is an independent marker of cardiovascular mortality in elderly female patients. The study thus introduces measurement of plasma CCK in gender-specific cardiovascular risk assessment.

Exact cause of the metabolic syndrome [MS], a global epidemic, is still unclear. Man has same fundamental needs to live as animals but modern man's life-style compels him to acquire certainty of resources for all his needs in a complex social network. Today money has become the sole life essential need. Contrarily none of the animals needs to earn money. Brain is also an organ of the human body with a unique thought process to define logical actions to achieve a person's goals. This way life is a flow of desires followed by logical actions. The person struggles to attain desired goals via the allostatic load but a perceived insurmountable threat can make his flow of life stalled to freeze him. Published data from varied branches of medical science indicates role of hormones in overall homeostasis. Particularly multifaceted role of serotonin is well documented. Adrenalin being the primary mediator of Cori cycle is also well known. From the integration of observations from published data with reference to common human's modern lifestyle, it is hypothesized that a perceived trapped situation in life creates acute chaos of thoughts in brain, which results in acute excess of stress hormones and concurrent depletion of resting hormones, which in turn triggers MS. In global terms, MS indicates an acute imbalance of a few hormones and implies psychosomatic roots of the disorder. This may pave a better way in deciding a personalized holistic protocol with combination of counter regulatory psychoactive medications.
