Caspase 9 and Caspase 3 Immunohistochemical Pattern in Skeletal and Cardiac Muscles at Different Times after Death: An Experimental Study on PMI Estimation

(1) Background: The estimation of the post mortem interval (PMI) is a challenge for forensic pathologists because data emerging from methods commonly applied are not always conclusive, since several conditions exist that may affect the reliability of these parameters. Thus, new approaches have been proposed to overcome such a limit. In recent years, several studies have been performed on proteins analyzing their expression/degradation patterns in relation to the progressing of the post mortem interval. (2) Methods: The immunoreactivity patterns of two apoptosis mediators—Caspase 9 and Caspase 3—have been tested in order to evaluate their potential role as markers of the post mortem interval…

Analysis on sarcoglycans expression as markers of septic cardiomyopathy in sepsis-related death

The post-mortem assessment of sepsis-related death can be carry out by many methods recently suggested as microbiological and biochemical investigations. In these cases, the cause of death is a multiple organ dysfunction due to a dysregulated inflammatory response occurring after the failure of infection control process. It was highlighted also that the heart can be a target organ in sepsis which determines the so-called septic cardiomyopathy characterized by myocardial depression. Several mechanisms to explain the pathophysiology of septic cardiomyopathy were suggested, but very few studies about the structural alterations of cardiac cells responsible for myocardial depression were carried…

Pasireotide treatment reduces cardiometabolic risk in Cushing’s disease patients: an Italian, multicenter study

Purpose: Patients with Cushing’s disease (CD) experience metabolic alterations leading to increased cardiovascular mortality. Recently, the visceral adiposity index (VAI) has been proposed as a marker of visceral adipose tissue dysfunction (ATD) and of the related cardiometabolic risk. We aimed to evaluate the impact of 12-month pasireotide treatment on cardiometabolic risk in CD patients. Methods: This is a multicentre, prospective, and observational study. Sixteen CD patients, referred to the Endocrine Units of the University Hospitals of Messina, Napoli, Padova, and Palermo (Italy), successfully treated with pasireotide for 12 month have been enrolled.

Persistence on Anti-Tumour Necrosis Factor Therapy in Older Patients with Inflammatory Bowel Disease Compared with Younger Patients: Data from the Sicilian Network for Inflammatory Bowel Diseases (SN-IBD)

BACKGROUND AND OBJECTIVE: Older people with inflammatory bowel disease (IBD) appear to have a lower response to anti-tumour necrosis factor (TNF) therapy, with more frequent complications than younger patients. The objective of this study was to assess persistence on therapy and the safety of anti-TNF therapy in older patients (aged ≥ 60 years). METHODS: We retrospectively reviewed the database of the Sicilian Network for Inflammatory Bowel Diseases (SN-IBD), extracting data regarding IBD patients aged ≥ 60 years and controls < 60 years of age at their first course of anti-TNF treatment. Data concerning persistence on therapy over the first year of treatment (primary objective) together …

Genistein supplementation and cardiac function in postmenopausal women with metabolic syndrome: Results from a pilot strain-echo study

Genistein, a soy-derived isoflavone, may improve cardiovascular risk profile in postmenopausal women with metabolic syndrome (MetS), but few literature data on its cardiac effects in humans are available. The aim of this sub-study of a randomized double-blind case-control study was to analyze the effect on cardiac function of one-year genistein dietary supplementation in 22 post-menopausal patients with MetS. Participants received 54 mg/day of genistein (n = 11) or placebo (n = 11) in combination with a Mediterranean-style diet and regular exercise. Left ventricular (LV) systolic function was assessed as the primary endpoint, according to conventional and strain-echocardiography measurement…

Oral and dental health of Italian drug addicted in methadone treatment

Objectives: Our group recorded the characteristic of oro-dental health among a group of drug addicts in recovery treatment with methadone, and it evaluated the changes related to the withdrawal therapy. Methodology: A sample of 50 drug addicts in treatment with methadone was included in this study. At the beginning of the withdrawal therapy, the authors recorded the parameters involved in the most common oral diseases. Moreover, it was evaluated how, during the rehabilitation protocol, the behavioral parameters and the xerostomia that influence the oral health changed. A medical history especially referring to drug addiction features was made. An intraoral objective exam was done for each p…

Dystrophin and metalloproteinase 9 in myocardial ischemia: A post-mortem immunohistochemical study

The presented study evaluated the expression of dystrophin and MMP-9 in cases of sudden cardiac death (SCD) due to coronary atherosclerotic disease (CAD) in order to analyze the characteristics and the chronology of their expression, providing evidence on the possible role in post-mortem diagnosis of myocardial ischemia. The expression of these proteins was also compared to C5b-9 complex and fibronectin expression to evaluate any differences. Two groups of CAD-related SCD, respectively group 1 with gross and/or histological evidence and group 2 with no specific histological signs of myocardial ischemia, were used. A third group formed by cases of acute mechanical asphyxiation was used as a …

Late-onset Crohn's disease: a comparison of disease behaviour and therapy with younger adult patients: the Italian Group for the Study of Inflammatory Bowel Disease 'AGED' study

BACKGROUND Disease phenotype and outcome of late-onset Crohn's disease are still poorly defined. METHODS In this Italian nationwide multicentre retrospective study, patients diagnosed ≥65 years (late-onset) were compared with young adult-onset with 16-39 years and adult-onset Crohn's disease 40-64 years. Data were collected for 3 years following diagnosis. RESULTS A total of 631 patients (late-onset 153, adult-onset 161, young adult-onset 317) were included. Colonic disease was more frequent in late-onset (P < 0005), stenosing behaviour was more frequent than in adult-onset (P < 0003), but fistulising disease was uncommon. Surgery rates were not different between the three age groups. Syste…

The relationship between transient elastography and histological collagen proportionate area for assessing fibrosis in chronic viral hepatitis

Collagen proportionate area (CPA) has a better correlation with hepatic venous pressure gradient (HVPG) than with Ishak stage. Liver stiffness measurement (LSM) is proposed as non invasive marker of portal hypertension/disease progression. Our aim was to compare LSM and CPA with Ishak staging in chronic viral hepatitis, and HVPG in HCV hepatitis after transplantation. One hundred and sixty-nine consecutive patients with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections pre/post liver transplantation (LT), had a liver biopsy combined with LSM (transient elastography), CPA (biopsies stained with Sirius Red and evaluated by digital image analysis and expressed as CPA) and H…
