Clinical and subclinical cardiovascular disease in female SLE patients: Interplay between body mass index and bone mineral density

Background and aims

Since accelerated atherosclerosis has been reported in systemic lupus erythematosus (SLE), predictive biomarkers of cardiovascular disease (CVD) are needed. Among non-traditional risk factors, bone mineral density (BMD) has been related to CVD. However, its role in SLE remains controversial. This study aims to analyze the associations of subclinical atherosclerosis with traditional and non-traditional CV risk factors.

Human epididymis protein 4 (HE4) levels inversely correlate with lung function improvement (delta FEV1) in cystic fibrosis patients receiving ivacaftor treatment

Background

We have recently shown that human epididymis protein 4 (HE4) levels correlate with the severity of cystic fibrosis (CF) lung disease. However, there are no data on how HE4 levels alter in patients receiving CFTR modulating therapy.

Short-term prognosis of patients with acute coronary syndromes through the evaluation of physical activity status, the adoption of Mediterranean diet and smoking habits: the Greek Acute Coronary Syndromes (GREECS) study.

PURPOSE: Our aim was to evaluate whether healthy dietary habits, physical activity and non-smoking are associated with less severe acute coronary syndromes and better short-term prognosis. SUBJECTS AND METHODS: From October 2003 to September 2004, 2172 patients (1649 males), hospitalized for severe acute coronary syndromes in six major hospitals in Greece were included in the study. The severity of severe acute coronary syndromes was assessed through troponin-I and maximum creatinine kinase MB levels, while 30-day recurrent event rate (death or rehospitalization for cardiovascular disease, angioplasty or coronary artery bypass surgery) was used to evaluate the prognosis of the patients. A 'healthy index' that assessed adherence to the Mediterranean diet, moderate alcohol intake, physical activity and abstinence from smoking was developed (range 0-4). RESULTS: One unit increment in the healthy index was associated with -12.4+/-2.4 ng/ml decrease in troponin I levels (P=0.001) and -9.7+/-2.5 ng/ml decrease in maximum creatinine kinase MB levels (P=0.001). The in-hospital mortality rate was 3.2% in males and 5.7% in females (i.e. overall 82 deaths, P=0.009); during the first 30 days following hospitalization the event rate was 15.7% in males and 16.3% in females (P=0.001). Values of the healthy index above one (i.e. presence of two or more protective factors) seemed to be associated with 44-84% lower risk of having recurrent events (P<0.001), even after various adjustments were made. CONCLUSION: Among patients who had had severe acute coronary syndromes, a healthy lifestyle seemed to be associated with less severe cardiac events and lower risk of death or rehospitalization 30 days after the event.     

Diabetes im Kindes- und Jugendalter

Type 1 diabetes is one of the commonest chronic disorders encountered in children and adolescents. When it first becomes apparent in children, approximately 20% of them have clinical and biochemical signs of ketoacidosis (DKA). In the presence of unusual clinical symptoms it is necessary to consider the possibility of associated conditions, such as coeliac disease, immunothyroiditis and Addison’s disease. Children with diabetes must be treated by a multidisciplinary team made up of paediatrician, paediatric diabetes specialist, psychologist, social worker, ophthalmologist, dietitian, nurse and diabetes counsellor, making it essential for them to be treated in regional specialised centres. They are treated in their own psychosocial environment and their families are involved in the therapy. Comprehensive, multidisciplinary treatment strategies have now made it possible for these patients to enjoy normal physical wellbeing and near-normal psychosocial development. Prevention and early treatment of of disturbances associated with diabetes remain an important concern. The fact that type 2 diabetes must now be looked for in overweight children and adolescents is a new aspect of diabetes medicine.     

Chronische Transplantatdysfunktion

Chronic transplant dysfunction is a complex dynamic pathogenic process. Clinically, a decrease in glomerular filtration rate (GFR) becomes apparent leading to chronic renal insufficiency and dialysis or death from cardiovascular events. Chronic transplant dysfunction can develop into a chronic alIograft nephropathy (CAN) as a specific entity with dynamic progression. CAN includes a collection of immunologic and non-immunologic factors, rejection, ischemia time, donor and recipient characteristics and toxicity of calcineurin inhibitors. Despite improvements in immunosuppression, the long-range prognosis of renal allografts has not improved. Whether modern immunosuppressive concepts with reduction or avoidance of calcineurin inhibitors and a therapy based on antimetabolites, such as mycophenolate or mTOR-inhibitors could lead to a prolongation of transplant survival, remains to be seen.     

Multi-day radon signals with a radioactive decay limb -- occurrence and geophysical significance.

Multi-day signals, generally with duration of 2-10 days, are a prominent temporal variation type of radon (Rn) in geogas in the unsaturated zone. Rare multi-day Rn signals have been found which are characterized by: (a) a declining limb lasting up to 10 days which conforms to the radioactive decay of Rn, (b) recurs at the same location and (c) is recorded in diverse situations-volcanic and seismogenic. It suggested that a Rn blob is injected at a lower level on a steady upward flow of geogas whereby the rise and final fall of the signal are attributed to the edges of the blob while the central Rn-decay segment records the passing of the decaying blob itself. Rn-decay signals are a small subset of multi-day Rn signals which are considered as highly irregular and unusable for the understanding of geophysical processes. In difference, it is concluded that multi-day Rn signals are probably proxies of subtle geodynamic processes at upper crustal levels and are therefore significant for studying such processes.
