“…This entity is relatively common with a prevalence that increases with the age of individuals. The metabolic syndrome predisposes both to the occurrence of type 2 diabetes and cardiovascular complications [1]. Several of the metabolic syndrome have been proposed, in particular that of the WHO, the IDF, and the NCEP ATP III.…”

Introduction:The metabolic syndrome according to the IDF (International Diabetes Federation) is at the origin of the double global epidemic of type 2 diabetes and cardiovascular diseases. This work aims to study the metabolic syndrome in the internal medicine department of CHU Point G. Methodology: This was a descriptive study of patients who presented a metabolic syndrome according to the definition of the IDF definition, hospitalized in the internal medicine department of the CHU du point G for the period from January 1 2010 to December 31, 2019. Results: During the study period, 4189 patients were hospitalized, including 60 with metabolic syndrome, representing a hospital frequency of 1.43%. The sex ratio was 0.36. The age group of 50 and 60 years accounted for 28.3%. Forty-six point six percent (46.6%) of our patients were diabetic, 45% obese, 60% hypertensive, 70% sedentary and 10% smokers. Our patients had in 53.3% of cases a blood pressure figure ≥ 130/85 mmHg, abdominal obesity in 100%, hypertriglyceridemia in 33.3%, HDL-C less than 0.40 g/l in 62.5% of men and less than 0.50 g/l in 77.27% of men, blood sugar ≥ 1 g/l in 88.3%. Conclusion: The metabolic syndrome, in view of the entities that compose it, is a real cardiovascular risk factor and therefore a major public health issue.

-Repulsive gravity is not very popular in physics. However, one comes across it in at least two main occurrences in general relativity: in the negative-r region of Kerr spacetime, and as the result of the gravitational interaction between matter and antimatter, when the latter is assumed to be CPT-transformed matter. Here we show how these two independent developments of general relativity are perfectly consistent in predicting gravitational repulsion and how the above Kerr negative-r region can be interpreted as the habitat of antimatter. As a consequence, matter particles traveling along vortical geodesics can pass through the throat of a rotating black hole and emerge as antimatter particles (and vice versa). An experimental definitive answer on the gravitational behavior of antimatter is awaited in the next few years.Introduction. -Nearly 100 years ago, on the Russian front, Karl Schwarzschild found the first exact solutions to the Einstein field equations, a few weeks after the publication of the general theory of relativity (and a few months before dying). These solutions describe the geometry of empty spacetime around an uncharged, spherically-symmetric, and non-rotating body [1]. The generalization to a charged source was found soon after [2,3]. However, it took almost fifty years to discover the exact solutions for a rotating, axially-symmetric object, which were found by Kerr in 1963 [4]. As usual, the extension to the charged case, i.e. the Kerr-Newman solution, followed shortly thereafter [5]. Further contributions to the investigation of the Kerr metric came in several papers in the following years (e.g. [6][7][8][9][10][11]). In particular, efforts were spent to understand the complete topology of Kerr spacetime.A peculiar aspect of this topology, which was not present in the static Schwarzschild case and in its analytic extensions (e.g. [12][13][14][15]), is the existence of the negative-r region, i.e. the r coordinate is no longer conditioned by the usual restriction r ≥ 0, but is allowed to take also negative values, as a Cartesian coordinate. To a physicist this freedom may appear rather embarrassing, also because it is not easy to explain what sense may have this 'doubling' of space of which he had never felt the need before. Here we investigate the properties of this unknown region and seek to give a physical interpretation.

“…There are many huge challenges on measuring the gravity of antimatter at present technology. The only direct experimental result [11] on antimatter gravity comes from Supernova 1987A which is in the Large Magellanic Cloud emitted both neutrinos and antineutrinos. Some neutrinos and antineutrinos took about 160,000 years to reach the Earth, and while traveling were bent from a "straight line" path by the gravity from our own galaxy.…”

Basing on the energy conservation, an analysis method on the gravity of antimatter is proposed by investigating the change of potential energy during high energy photon transfers to electron and positron in earth gravity field. Potential energy equations are deducted and proved that the force between matter and antimatter is attractive, and then the force between antimatter and antimatter is proved to be attractive too. So the gravity is attractive without considering matter or antimatter.
