Family hystory, diabetes and extension of coronary atherosclerosis are strong predictors of adverse events after PTCA: a one year follow-up study
2005
BACKGROUND AND AIM: In this study we addressed some open questions in patients with coronary artery disease (CAD). First, we analysed which of the traditional risk factors was associated with the spreading of coronary stenosis and second, we aimed to identify if any variable was predictive of post-percutaneous transluminal coronary angioplasty (PTCA) clinical events. METHODS AND RESULTS: We collected a consecutive series of patients with CAD (n=301) and in the subgroup of patients undergoing PTCA (n=135) we performed a prospective one-year follow-up study recording cardiovascular morbidity and total mortality. According to the extension of coronary atherosclerosis, we found a significant re…
Musculoskeletal fitness and balance in older individuals (65–85 years) and its association with steps per day: a cross sectional study
2015
Background There is limited normative, objective data combining musculoskeletal fitness (MSF), balance and physical activity (PA) among older adults. The aims were therefore to; 1) describe MSF and balance in older Norwegian adults focusing on age- and sex-related differences; 2) investigate the associations among MSF, balance and objectively-assessed PA levels. Methods This was part of a national multicenter study. Participants (65–85 years) were randomly selected from the national population registry. We used ActiGraph GT1M accelerometers to measure PA. Balance and MSF were assessed using: one leg standing (OLS), handgrip strength (HG), static back extension (SBE), sit and reach (SR), bac…
Cell-Free Circulating Plasma hTERT mRNA Is a Useful Marker for Prostate Cancer Diagnosis and Is Associated with Poor Prognosis Tumor Characteristics
2012
BackgroundSerum prostate-specific antigen (PSA) is the most widely used marker for diagnosing prostate cancer (PCa). It lacks specificity and predictive value, resulting in inaccurate diagnoses and overtreatment of the disease. The aim of this study was to assess the usefulness of plasma telomerase reverse transcriptase (hTERT) mRNA as a diagnostic and prognostic tool for PCa and its association with clinicopathological parameters of tumors.Principal findingsPlasma hTERT mRNA levels were determined by qRT-PCR in 105 consecutive patients with elevated PSA levels and in 68 healthy volunteers. The diagnostic accuracy, the efficacy as a prognostic factor of biochemical recurrence and the associ…
BRAF(V600E) MUTATION AND THE BIOLOGY OF PAPILLARY THYROID CANCER
2008
BRAF((V600E)) mutation is the most frequent genetic alteration in papillary thyroid carcinomas (PTCs) that are 80-90% of all thyroid cancers. We evaluated the relationship between BRAF((V600E)) and tumor, host, and environmental factors in PTCs from all geographical areas of Sicily. By PCR, BRAF((V600E)) was investigated in a series of 323 PTCs diagnosed in 2002-2005. The correlation between clinicopathological tumor, host, and environmental characteristics and the presence of BRAF((V600E)) were evaluated by both univariate and multivariate analyses. BRAF((V600E)) was found in 38.6% PTCs, with a 52% frequency in the classical PTCs and 26.4% in the tall cell variant. Univariate analysis indi…
Factors influencing survival after resection of pancreatic cancer. A DNA analysis and a histomorphologic study
1994
BACKGROUND The influence of DNA content on prognosis in stomach cancer has been investigated rarely, and the results are controversial. METHOD The prognostic relevance of the DNA content and histomorphologic parameters was evaluated in 41 patients after resection of pancreatic cancer. RESULTS In the univariate analysis, the DNA content, tumor size, lymph node status, tumor stage, nuclear grade, and type of resection had a statistically significant influence on the prognosis. No association was found between the DNA content and the histomorphologic features. Apart from the operative procedure, the DNA content was the strongest indicator of prognosis in the multivariate analysis. CONCLUSIONS …
Postponed Is Not Canceled: Role of Craniospinal Radiation Therapy in the Management of Recurrent Infant Medulloblastoma—An Experience From the HIT-RE…
2013
Purpose To evaluate the efficacy of craniospinal irradiation (CSI) in the management of recurrent infant medulloblastoma after surgery and chemotherapy alone. Methods and Materials Seventeen pediatric medulloblastoma patients registered in the HIT-REZ 1997 and 2005 studies underwent CSI as salvage treatment at first recurrence. All patients had achieved complete remission after first-line treatment consisting of surgery and chemotherapy. Eleven patients showed metastatic disease at relapse. Five patients underwent surgery prior to radiation therapy, which resulted in complete resection in 1 case. In 1 patient, complete resection of the residual tumor was performed after CSI. Eleven patients…
Severe hypovitaminosis D correlates with increased inflammatory markers in HIV infected patients
2013
Abstract Background Even though it has been suggested that antiretroviral therapy has an impact on severe hypovitaminosis D (SHD) in HIV infected patients, it could be speculated that the different levels of residual inflammation on HAART (Highly Active Anti Retroviral Therapy) could contribute to SHD and aggravate bone catabolism in these patients. Methods A cross-sectional study was carried out in an unselected cohort of 263 HIV infected outpatients consulting during Spring 2010. Clinical examinations were performed and medical history, food habits, sun exposure and addictions were collected. Fasting blood samples were taken for immunological, virological, inflammation, endocrine and bone…
Is there a lack of information on HPV vaccination given by health professionals to young women?
2013
Objective: The aim of this survey is to compare the main sources of information about vaccination against Human papillomavirus (HPV) of young women aged over-18 and under-18 years.Methods: A multicenter study was carried out in Italy through the administration of a questionnaire. Univariate analyses were conducted to evaluate possible differences between age groups and different locations (chi-square test and Fisher test where possible).Results: The sample consisted of 987 young women. The main sources of information about HPV vaccination are represented by magazines/books (23.1%) and TV (20.5%) for the over-18s, while for the under-18s the sources are general practitioners (22.6%) and pedi…
An international multicentre prospective audit of elective rectal cancer surgery; operative approach versus outcome, including transanal total mesore…
2018
Introduction: Transanal total mesorectal excision (TaTME) has rapidly emerged as a novel approach for rectal cancer surgery. Safety profiles are still emerging and more comparative data is urgently needed. This study aimed to compare indications and short-term outcomes of TaTME, open, laparoscopic, and robotic TME internationally. Methods: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 audit was performed. Patients undergoing elective total mesorectal excision (TME) for malignancy between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary outcome measure was anastomotic leak. Results: Of 2579 included patients, 76.2% (1966/257…
Systemic inflammatory status at baseline predicts bevacizumab benefit in advanced non-small cell lung cancer patients.
2013
Bevacizumab is a humanized anti-VeGF monoclonal antibody able to produce clinical beneit in advanced non-squamous non-small cell lung cancer (nsCLC) patients when combined to chemotherapy. At present, while there is a rising attention to bevacizumab-related adverse events and costs, no clinical or biological markers have been identiied and validated for baseline patient selection. preclinical indings suggest an important role for myeloid-derived inlammatory cells, such as neutrophils and monocytes, in the development of VeGF-independent angiogenesis. We conducted a retrospective analysis to investigate the role of peripheral blood cells count and of an inlammatory index, the neutrophil-toly…
