The role of macrophage colony-stimulating factor in patients with acute myocardial infarction: a pilot study

We assessed whether macrophage colony-stimulating factor (M-CSF) levels are associated with left ventricular systolic dysfunction (LVSD) in patients with acute myocardial infarction (AMI). We studied 56 patients with AMI (mean age: 67 ± 12 years) and identified those with clinical (Killip class >II) or echocardiographic signs (ejection fraction ≤45%) of LVSD. We evaluated the established cardiovascular risk factors and measured several cardiovascular biomarkers, including M-CSF. Serum M-CSF concentrations (pg/mL) were significantly increased in patients with both clinical and echocardiographic signs of LVSD (460 ± 265 vs 290 ± 210, P = .0103 and 493 ± 299 vs 287 ± 174, P = .0028, respectively). We found a significant inverse association between M-CSF and ejection fraction (r = -.351, P = .0079). Logistic regression analysis revealed that, among all evaluated clinical and biochemical parameters, the stronger predictor of LVSD was M-CSF (odds ratios 2.1, 95% confidence interval 1.1-2.9, P = .0168). This is the first study reporting plasma M-CSF levels as independent determinants of low LV ejection fraction and clinical LV dysfunction in patients with AMI.     

Case involving CAD/CAM-generated, screw-retained bridge demonstrates dentistry's scientific progression

The patient in the case presented had successfully used a maxillary overdenture for more than three decades. However, the time had come for the prosthetic appliance to be replaced. This case, which involved the use of a titanium understructure that was designed and fabricated using CAD/CAM technology, illustrates how far dentistry has come since the patient first presented to the clinician some 35 years ago when dental science had not yet included such innovations as bone grafting and CT scans.     

Vasospastic angina and scombroid syndrome: a case report

Scombroid syndrome is a fish poisoning characterised by the onset of symptoms compatible with a pseudoallergic reaction; it is rarely also responsible of signs and symptoms of acute coronary syndromes, as demonstrated in this case report.     

Long-term use of deferiprone significantly enhances left-ventricular ejection function in thalassemia major patients

A multicenter randomized open-label long-term sequential deferiprone–deferoxamine (DFP-DFO) versus DFP alone trial (sequential DFP-DFO) performed in patients with thalassemia major (TM) was retrospectively reanalyzed to assess the variation in the left ventricular ejection fraction (LVEF) [1].     

Methylenetetrahydrofolate reductase homozygosis and low-density lipoproteins in patients with genotype 1 chronic hepatitis C

Methylenetetrahydrofolate reductase status, homocysteine and lipoproteins levels have been associated with severity of disease and both rapid and sustained virological response (SVR) in patients with genotype 1 chronic hepatitis C (CHC). We aimed to assess the association of homocysteine and MTHFR status with serum cholesterol levels and their potential links to both histological findings and virological response, in patients with genotype 1 hepatitis C virus (HCV). A total of 119 consecutive patients were evaluated by biopsy and metabolic measurements. A total of 103 healthy blood donors were used as controls. Serum homocysteine and MTHFR C677T mutation were also evaluated. All patients underwent antiviral therapy with PEG-IFN alfa-2a plus ribavirin. HCV-RNA was assessed at baseline, week 4, week 12, at the end of therapy and after 6 months of follow-up. Mean serum values of homocysteine were higher in patients than in controls (15.8 ± 5.8 μg/L vs 12.5 ± 5.8 μg/L; P < 0.001), with a similar CC, CT and TT MTHFR distribution (23.6%, 48.7% and 27.7% in G1-CHC vs 34%, 48.5% and 17.5% in controls; P = 0.14). In genotype 1, HCV MTHFR TT homozygosis was independently linked to higher LDL (OR 1.016; CI 1.002-1.031; P = 0.03), but not to homocysteine. No association were found between homocysteine, MTHFR and histological features or both rapid virological response (RVR) and SVR. Low cholesterol (OR 0.988, 95%CI 0.975-0.999, P = 0.04) was independently linked to severe fibrosis, and high LDL was the only independent positive predictors of both RVR and SVR (OR 1.036; 95%CI 1.017-1.055; P < 0.001; and OR 1.016; 95%CI 1.001-1.031; P = 0.04 respectively). In patients with genotype 1 hepatitis C, showing higher homocysteine serum levels than controls, MTHFR C677T homozygosis, via modulating cholesterol levels, could interfere with liver fibrosis and response to antiviral therapy.     

Mediterranean diet and longevity in Sicily: survey in a Sicani Mountains population

Over the past several years, increasing evidence suggests that the Mediterranean diet has a beneficial influence on several age-related diseases, showing protective effect on health and longevity. Mediterranean diet refers to dietary patterns found in olive-growing regions of the Mediterranean countries. Previous data reported that in Sicily, Italy, the largest Mediterranean island, there are some mountainous regions where there is a high frequency of male centenarians with respect to the Italian average. The aim of the present study was to characterize centenarians living in one of this region, the Sicani Mountains, located in western Sicily. Present data shows that in this zone there are more centenarians with respect to the Italian average. In fact, in the three villages of the Sicani Mountains, there were 15 people ranging from 100 to 107 years old, of the total population of about 10,000 inhabitants. This centenarian number was more than six-fold higher the national average (15.0 vs. 2.4/10,000); the female/male ratio was 1.5 in the study area, whereas the national ratio is 4.54. Centenarians living in these villages had anthropometric measurements within normal limits and moderate sensory disability without any sign of age-related diseases, including cognitive deterioration and dementia. In addition, their clinical chemistry profile was similar to young controls and far better than that of old controls. Unequivocally, their nutritional assessment showed a high adherence to the Mediterranean nutritional profile, with low glycemic index food consumed. Overall, close adherence to Mediterranean diet seems to play a key role in age-related disease prevention and in attaining longevity.     

Infektionsschutzrecht

Background

Legal regulations concerning infection protection have been repeatedly revised in the last few years. At the national level the regulations for notifable diseases were recently broadened to include the suspicion of disease, the disease and death due to mumps, pertussis, rubella including congenital rubella and varicella (chickenpox). In addition notification deadlines were shortened in the new regulations and the information to be reported was expanded. At the “Bundesländer” level, there are also new regulations which expand notification concerning diseases and are extended to other contagious diseases. In addition, infection protection also includes measures to prevent and combat contagious diseases.
