Research on pathological calcifications constitutes an exciting topic at the interface between physics, chemistry and medicine. The relationship between their physicochemical characteristics and the pathology responsible for their formation offers a unique opportunity to perform a significant medical diagnosis, to assess the interaction between drugs and these biological entities as well as to develop new drugs. Regarding synchrotron radiation, the emergence of microbeam allows the clinician to perform an early diagnosis. Indeed, we will start this review with a clinical case where Fourier transform infrared spectroscopy using synchrotron radiation as a probe allowed the clinician to save the kidney function of a patient. Following this example, we will see that investigations on pathological calcifications constitute an elegant way to gather major information on different public health problems such type 2 diabetes as well as on rare diseases. To attain this goal, this mini-review dedicated to structural and chemical investigations and based on selected and recent data collected through techniques using third generation synchrotron radiation as a probe is proposed to the reader.

Background: Diabetes mellitus (DM) is a common metabolic disease worldwide and has many complications. The vascular events are the major complication of DM that have an important effect on mortality and disability. The physical activity (PA) enhances the vascular function by several pathways. The aim of this study was to evaluation of the relationship between PA and vascular diseases in patients with DM.Materials and Methods: This research was performed as the case-control study that was extracted from a prospective epidemiological research study in Iran (PERSIAN). The patients with type 2 DM more than six months defined as case group and the non-DM subjects in control group with ratio 1:2, and both groups were matched in the term of age and sex. The MET score was used to evaluate the level of PA and blood glucose, lipid profile, body mass index, overweight, dyslipidemia, glomerular filtration rate, myocardial infarction (MI), unstable angina, and stroke.Results: Overall, 1242 patients with DM were extracted, and 2484 non-diabetic subjects were investigated. In the case group, 355(28.6 %) and 887(71.4%) were men and women, respectively, the and 710 (28.6%) men and 1774(71.4%) women in control group. The mean MET score was 30 and 40.97 in the DM and non-DM groups, respectively (P˂0.001). The frequency of MI, stroke, and cardiac ischemia were 44 (3.5%), 37 (3%), and 267 (21.5%), respectively in DM group, and 54 (2.2%), 43 (1.7%), and 389 (15.7%), respectively in non-DM group.Conclusion: The incidence of vascular events associated with PA level in patients with DM and adherence to regular PA reduce the vascular events and DM complications.

Transversal Study

In patients with obstructive sleep apnoea (OSA), a consequence of the intermittent hypoxia is nocturia. The frequency of nocturia related OSA is increased because many pathological pathways are present simultaneously. The aim was to assess the prevalence of nocturia among OSA patients and to identify the relationship with OSA and its comorbidities. A transversal study determining the prevalence of OSA�s comorbidities and nocturia related OSA and smoking was assessed, from 2011 to 2015, in 2 Romanian centres of Somnology, in Constanta county. All patients suspected of sleep breathing disorders were investigated by polygraphy and all patients diagnosed with OSA were recruited. Demographic and clinical characteristics were assessed, including the onset of nocturia. The comparison between groups with and without nocturia was performed using SPSS software, using Anova for numerical outcomes and c2 test for the categorical ones. Nocturia was highly prevalent (62.75 %) among 204 OSA patients, especially in elderly (p [ 0.00001). High blood pressure (hypertension), obstructive pulmonary disease (COPD), smoking exposure were more frequently reported in the OSA patients presenting nocturia (p[0.05). Type 2 diabetes and cardiac failure were also frequent, but did not reach a significant threshold of 95%. In conclusion, the nocturia is a frequent symptom and it is influenced by the OSA severity and comorbidities as hypertension and COPD. A further multidisciplinary approach in these patients is justified, especially in smokers.
