Sepsis is one of the most important causes of morbidity and mortality in patients presenting to the emergency department. SIRS criteria that define sepsis are not specific and do not reflect the severity of infection. We aimed to evaluate the ability of the modified mortality in emergency department sepsis (MEDS) score, the modified early warning score (MEWS) and the Charlson comorbidity index (CCI) to predict prognosis in patients who are diagnosed in sepsis. ⋯ The MEDS score had a greater prognostic value compared to the MEWS and CCI scores. The performance of modified MEDS score was better than that of other scoring systems, in our study. Therefore, we believe that the modified MEDS score can be reliably used for the prediction of mortality in sepsis.

Congenital abnormalities of the coronary arteries here described are an uncommon form of structural heart disease. Nevertheless, they deserve attention because may cause chest pain and, in some cases, sudden cardiac death even during exercise. Traditional angiography has limitations due to its projectional and invasive nature. The recent development of the 320-slide multi-detector computer tomography with low radiation exposure has the potential to modify the current diagnostic work-up, as it allows even in young people a timely identification of clinical significant coronary anomalies minimizing the risks related to radiation exposure.

Symbiosis is the result of the relationship between gut microbiota and human surfaces; in fact, it regulates many functions such as metabolic and protective ones. It is widely known that any changes in the microbes in gut microbiota (dysbiosis) and the regulation of mucosal and systemic host's immunity have been linked to different diseases such as metabolic syndromes and associated disorders. ⋯ Most studies suggest that diet, especially the high-fat low-fiber western-style diet, dramatically impacts on gut microbiota composition and functions in those patients with metabolic syndrome. A deeper knowledge of a specific microbiota profile associated with increased risk of metabolic disease and its subsequent modification induced by prebiotics, probiotics or targeted antibiotics will be necessary for the development of new therapeutic approaches in the treatment of metabolic disease.

Polycystic ovary syndrome, the most common endocrine disorder of reproductive age women, is often associated with insulin resistance and associated disorders. The frequency of type 2 diabetes, hyperlipidemia, cardiac risk markers, structural vascular disease, and clinical disease events are increased in this population of women. ⋯ The role of insulin resistance and hence the risk of cardiometabolic disorders may in part be determined by the definition of PCOS used. Epidemiologic studies and clinical trials support the need to identify women with PCOS to determine their risk of cardiometabolic disorders to prevent and/or treat their serious consequences.

We investigated the effect of physical activity on heart rate variability (HRV) and carotid intima-media thickness (IMT) in elderly subjects and the relationship between HRV and IMT. Thirty-two elderly sedentary subjects and 32 age-matched endurance athletes underwent ultrasonography of the carotid wall for measuring IMT, and 24-h ECG monitoring for measuring HRV. Elderly athletes had evidence of increased vagal activity in the time (SDANN, rMSSD, and pNN50; p < 0.01) and frequency domain (HF and LF/HF ratio, p < 0.01) with respect to sedentary subjects. ⋯ In the whole population SDNN was inversely related to IMT, respectively (r = -0.60 and r = -0.58, p < 0.0001), while LF/HF ratio related positively to IMT. In conclusion, this study demonstrated that in aging HRV is negatively associated with IMT, a putative index of atherosclerosis, confirming cardiac autonomic neuropathy as part of the pathophysiological pathway for atherosclerosis. It confirms that the regular physical activity represents a valuable strategy to counter age-related impairments of cardiac autonomic activity and artery structural changes.
