Patterns of DNA-ploidy in operable colorectal carcinoma: A prospective study of 100 cases

1991

A prospective study of cellular DNA content was made by means of flow cytometry in a nonconsecutive series of 100 patients undergoing surgery for primary colorectal adenocarcinoma. DNA-aneuploidy was present in 80% of cases (80/100); 39% of these were multiclonal (31/80). There was no significant correlation between DNA-ploidy and the clinical and pathological features examined, except for the primary tumor site (right colon vs. left colon vs. rectum: P less than 0.001). After a minimum follow-up of 30 months, out of 40 patients with no local invasion and/or distant metastases, 100% (9/9) of those with DNA-diploid neoplasias showed no signs of disease relapse, vs. 55% (17/31) of the DNA-ane…

CT-guided intratumoral gene therapy in non-small-cell lung cancer.

1999

The objective of this study was to prove the principle of CT-guided gene therapy by intratumoral injection of a tumor suppressor gene as an alternative treatment approach of incurable non-small-cell lung cancer. In a prospective clinical phase I trial six patients with non-small-cell lung cancer and a mutation of the tumor suppressor gene p53 were treated by CT-guided intratumoral gene therapy. Ten milliliters of a vector solution (replication-defective adenovirus with complete wild-type p53 cDNA) were injected under CT guidance. In four cases the vector solution was completely applied to the tumor center, whereas in two cases 2 ml aliquots were injected into different tumor areas. For the …

MYD88 L265P mutation and interleukin‐10 detection in cerebrospinal fluid are highly specific discriminating markers in patients with primary central …

2021

Reliable biomarkers are needed to avoid diagnostic delay and its devastating effects in patients with primary central nervous system (CNS) lymphoma (PCNSL). We analysed the discriminating sensitivity and specificity of myeloid differentiation primary response (88) (MYD88) L265P mutation (mut-MYD88) and interleukin-10 (IL-10) in cerebrospinal fluid (CSF) of both patients with newly diagnosed (n = 36) and relapsed (n = 27) PCNSL and 162 controls (118 CNS disorders and 44 extra-CNS lymphomas). The concordance of MYD88 mutational status between tumour tissue and CSF sample and the source of ILs in PCNSL tissues were also investigated. Mut-MYD88 was assessed by TaqMan-based polymerase chain reac…

Appropriateness of upper-GI endoscopy: an Italian survey on behalf of the Italian Society of Digestive Endoscopy

2007

BACKGROUND AND OBJECTIVE: Open-access endoscopy allows physicians to directly schedule endoscopic procedures for their patients without prior consultation. An evaluation of both appropriateness and diagnostic yield of endoscopic procedures is critical when assessing the costs and benefits of endoscopy in an open-access setting. The aim of this Italian multicenter study was to assess the appropriate use of upper endoscopy (EGD) in an open-access system and to establish the yield of diagnostic information relevant to patient care. DESIGN AND SETTING: Cross-sectional, prospective, multicenter study. PATIENTS: A total of 6270 patients referred to 44 Italian centers for open-access EGD during 1 …

Ophthalmic Outcomes of Congenital Toxoplasmosis Followed Until Adolescence

2014

BACKGROUND: Congenital toxoplasmosis (CT) can elicit severe damage to several organs, especially the eye, and may be manifested at birth or later. We assessed the long-term ocular prognosis in a cohort of congenitally infected children treated according to a standardized protocol and monitored for up to 22 years. METHODS: This prospective study included confirmed cases of CT, which were identified by obligatory antenatal screening at the Lyon (France) reference center between 1987 and 2008. Data obtained through ocular examinations were recorded on a standardized form and confirmed by an independent external committee. Risk factors for retinochoroiditis were identified by using a multivari…

Factors associated with exclusive breast-feeding and breast-feeding in Norway

2010

Objective: To identify factors associated with exclusive breast-feeding and breastfeeding during the first year of life among Norwegian infants. Design: Data on breast-feeding practices were collected by a semi-quantitative FFQ. Setting: In 2006–2007 about 3000 infants were invited to participate in a populationbased prospective cohort study in Norway. Subjects: A total of 1490 mothers/infants participated at both 6 and 12 months of age. Results: Exclusive breast-feeding at 4 months was associated with parental education, parity and geographical region, while exclusive breast-feeding at 5?5 months was associated only with maternal age. At both ages, a negative association with exclusive bre…

Associations of Birth Weight and Postnatal Weight Gain With Cardiometabolic Risk Parameters at 5 Years of Age

2014

The present prospective study assessed the impact of birth weight (BW) and postnatal weight gain on blood pressure and metabolic profile during the first 5 years of life. One hundred thirty-nine newborns (63 women) born at term after uncomplicated pregnancies and in the absence of perinatal illness were included. Subjects were divided according to size at birth in small, appropriate, and large for gestational age. After the initial evaluation on the second day of life, infants were followed up at 6 months and 2 and 5 years. Anthropometric parameters and blood pressure were measured at each visit and metabolic assessment was performed at 5 years of age. Among the BW groups, mothers did not d…

Iodine intake from supplements and diet during pregnancy and child cognitive and motor development: the INMA Mother and Child Cohort Study

2017

BackgroundThe effect of mild-to-moderate maternal iodine deficiency on the neuropsychological development of their offspring is uncertain. We aimed to assess the association between iodine status during pregnancy and the cognitive and motor development of children at 4–5 years.MethodsWe conducted a prospective cohort study in four Spanish regions with recruitment of pregnant women between 2003 and 2008 and follow-up of their children up to 4–5 years (mean (SD)=4.8 (0.6)). Cognitive and motor function was assessed in 1803 children using the McCarthy Scales of Children’s Abilities. Dietary iodine and supplementation were measured through questionnaires twice during pregnancy. Urinary iodine c…

Association Between Exstrophy-epispadias Complex And Congenital Anomalies: A German Multicenter Study

2018

To further investigate associated anomalies in exstrophy-epispadias complex (EEC) patients congenital uro-rectal malformations network (CURE-Net) database was systematically screened. In literature the EEC comprises a spectrum of anomalies, mainly occurring "isolated" without additional congenital defects. Nevertheless, previous epidemiological studies indicated a higher association with renal, anorectal, and lower neurotubular anomalies, which may originate from the same developmental morphogenetic fields.Seventy-three prospectively (born since 2009) and 162 cross-sectional recruited EEC patients (born 1948-2008) were analyzed. Associated anomalies were derived from patient's medical data …
